Image-guided biopsy (Image-guided percutaneous biopsy)

A minor procedure in which a radiologist uses a scan to guide a needle and take a small sample of tissue or fluid for testing, to help reach a diagnosis.

✓ Medically reviewed by a GMC-registered consultant · last reviewed September 2026 · next review September 2027 · how we review

In short

It takes a small tissue or fluid sample to help reach a diagnosis — it is a test, not a treatment.
It is a minor procedure done through a needle puncture under local anaesthetic, not an operation, so there is no surgical scar.
Results take several days to a couple of weeks, and occasionally a sample is inconclusive and needs repeating.
Risks depend on the body part (for example a small risk of a collapsed lung for a lung biopsy); choose an experienced operator and follow the aftercare advice.

A plain-English summary. The detail — including risks and recovery — is below.

What is an image-guided biopsy?

A biopsy is when a small sample of tissue or fluid is taken so it can be examined under a microscope or tested in a laboratory. An image-guided biopsy uses a scan — usually ultrasound or CT, sometimes MRI — so the radiologist can see exactly where the needle is going and take the sample from the right place.

It is done through the skin ("percutaneous") with a thin needle, under local anaesthetic. Because there is only a needle puncture rather than an operation, it is a minor procedure: there is no surgical cut and no surgical scar. It is used to sample lumps, organs or abnormal areas found on a scan — for example in the breast, thyroid, lymph nodes, liver, kidney, lung, bone or other soft tissues.

The purpose of a biopsy is information, not treatment. It is often a key step in finding out whether something is harmless or serious, what type of problem it is, and how best to treat it. A biopsy cannot, by itself, make you better.

No test is perfect. Occasionally a sample does not contain enough useful tissue and the biopsy has to be repeated or done a different way. Your radiologist should explain what the biopsy is looking for and what happens whether the result is clear, reassuring or uncertain.

Types, options & approaches

There may be different ways to do this. The right approach depends on the clinical question and your circumstances.

Ultrasound-guided biopsy

Used for targets that show up well on ultrasound and are near the surface, such as the breast, thyroid, lymph nodes or liver. The needle is watched in real time and no X-rays are used.

CT-guided biopsy

A CT scanner gives detailed cross-sectional pictures to reach deeper or harder-to-see targets, such as the lung, some abdominal organs or bone.

Core needle biopsy

A slightly thicker needle takes one or more small cores of tissue, which keep their structure and usually give the most information for diagnosis.

Fine needle aspiration (FNA)

A very thin needle draws out cells or fluid. Less tissue is obtained than with a core biopsy, but it is useful for some targets such as the thyroid or lymph nodes.

Aspiration of fluid

When a target is a fluid collection or cyst, the radiologist may draw off fluid for testing rather than taking solid tissue.

Core biopsy vs fine needle aspiration

Point	Core biopsy	Fine needle aspiration
Needle	Slightly thicker	Very thin
Sample	Small cores of tissue	Cells or fluid
Information	Usually more detailed	Less, but often enough
Used for	Many solid lumps	Thyroid, nodes, fluid

Your radiologist chooses the method based on the target and what the laboratory needs to answer the clinical question.

Preparing for your procedure

Tell the team about all medicines, especially blood thinners (warfarin, apixaban, rivaroxaban, clopidogrel), which often need pausing before a biopsy.
A blood test to check clotting may be arranged beforehand, particularly for deeper organs such as the liver or kidney.
Mention any allergies, including to local anaesthetic or to X-ray dye if used.
Tell them if you are or might be pregnant, especially if CT guidance is planned.
Ask whether you need to fast, and whether and when to stop or adjust any medicines.
Arrange for someone to take you home if sedation is planned or you are having a lung or deep biopsy.
Plan some rest afterwards, especially for biopsies of the chest, abdomen or a weight-bearing area.

What happens

You are positioned so the radiologist can see the target on the scan. The skin is cleaned and local anaesthetic is injected to numb the area, which stings briefly and then makes the rest more comfortable.

Using ultrasound, CT or MRI for guidance, the radiologist passes a thin needle through the skin to the target and takes one or more samples. You may hear a small click with a core-biopsy device and feel pressure or a brief ache. Several samples are sometimes needed to be sure enough tissue is obtained.

The needle is removed and pressure is applied; a small dressing covers the puncture site. For some biopsies, such as the lung, you will be watched for a few hours and may have a chest X-ray afterwards. There is a needle puncture rather than a surgical cut, so there is no stitch and no surgical scar. The procedure itself usually takes about 20 to 60 minutes.

Is this procedure right for me?

A good consultation should explore whether it's the right choice for you now — including reasons to wait or consider something else.

May not be suitable if…

You have a bleeding tendency or take blood thinners that cannot be safely paused or corrected.
There is no safe path to the target without crossing important structures such as bowel or major vessels.
You could not lie still or hold your breath as needed for the biopsy.
The likely result would not change your management, so the test may not be worthwhile.
An active infection over the planned puncture site makes it unsafe for now.

Delay or rearrange if…

Your blood thinners or a clotting problem have not yet been reviewed.
You have an active infection or are acutely unwell.
You are or might be pregnant and CT guidance is planned.
Key earlier scans or results that should guide the biopsy are missing.
Your symptoms have changed and the plan needs reviewing first.

Alternatives to discuss

Watchful waiting with repeat scans if an abnormality looks low-risk.
A surgical (open or keyhole) biopsy if a needle sample is not feasible or has failed.
A different, less invasive test where one can answer the question.
Treating on the basis of scans and clinical findings alone in selected cases.
A second opinion on the imaging before deciding whether a biopsy is needed.

Before you decide

Use this as a shared-decision checklist. The aim is not just “can this be done?”, but whether it is right for you, now, with the risks and alternatives clearly understood.

What matters most to me?

Think about symptoms, daily life, work, caring responsibilities, sport, fertility, travel, appearance and anxiety — the right choice depends on your priorities, not just the medical facts.

What are all my options?

Ask about waiting, monitoring, medicines, rehabilitation, a smaller or larger procedure, a different test, NHS referral, or a second opinion where that would help.

What would make me pause?

Active infection, pregnancy, unstable medical problems, smoking, medicines that increase bleeding, poor support at home, or feeling pressured are all reasons to slow down and get tailored advice.

What happens if I do nothing today?

For some problems, waiting is safe; for others, delay can make treatment harder. A good consultation should explain the trade-off in plain English.

Comfort, sedation or contrast choices

If local anaesthetic, sedation, contrast or pain relief is used, ask what is planned, why, and what it means afterwards.

Local anaesthetic

Standard for most image-guided biopsies; numbs the skin and tissue along the needle path.

Sedation

Occasionally used for deeper, longer or more uncomfortable biopsies; you would then need someone to take you home.

Benefits

Can provide a precise tissue diagnosis to guide treatment
Image guidance helps sample the right area accurately, including small or deep targets
Much less invasive than a surgical (open) biopsy, with quicker recovery
Can confirm whether a lump is harmless or needs treatment
Can show the exact type of a problem, which can change the whole treatment plan
Usually done as an outpatient or day case under local anaesthetic

Risks & complications

More common

Bruising, soreness or a small amount of bleeding at the puncture site
Mild pain around the area for a day or two
Anxiety while waiting for results
Occasionally a sample that does not contain enough tissue, needing a repeat

Less common

More noticeable bleeding, especially after biopsy of organs such as the liver or kidney
Infection at the puncture site or in the sampled area
For a lung biopsy, a partial collapse of the lung (pneumothorax) and sometimes coughing up a little blood
Site-specific effects depending on the organ sampled

Rare but serious

Significant bleeding needing treatment, a transfusion or, very rarely, a further procedure
A lung collapse large enough to need a chest drain
Serious infection
Injury to a nearby structure such as a blood vessel, nerve or other organ

The main risks are bleeding and infection, and they depend a great deal on which part of the body is sampled and on your clotting. A lung biopsy carries a specific risk of a collapsed lung that can need a chest drain; liver and kidney biopsies carry a higher bleeding risk. Make sure your blood thinners and any clotting problems have been reviewed, and ask what the specific risks are for your biopsy and what urgent signs to watch for.

Published figures to discuss

Complication rates depend heavily on which organ is sampled, the needle used and the patient's clotting, so figures vary widely between studies. Most complications are mild; serious ones are uncommon. Lung biopsy has well-recognised, higher rates of a collapsed lung than most other sites.

Figure	Reported range	How to interpret it	Source / confidence
Pneumothorax (collapsed lung) after CT lung biopsy	Commonly reported up to around 25% of lung biopsies; most are small and need no treatment	Roughly 5% may need a chest drain; rates vary with lesion depth, size and technique.	Complication rates under ultrasound and CT guidance — PMC reviewncbi.nlm.nih.govPublished figure
Bleeding after lung biopsy	Pulmonary bleeding reported in up to around 20% in some series	Usually minor; may cause a little coughing of blood that settles.	Complication rates under ultrasound and CT guidance — PMC reviewncbi.nlm.nih.govPublished figure
Inadequate or inconclusive sample	Varies by site and target; a minority of biopsies need repeating	More likely with small, deep or hard-to-reach targets.	Guide sourcesClinical context

These are literature figures, not a personalised prediction. Your own risks and likely benefits depend on your circumstances, your health, and how your care is carried out and followed up.

What happens afterwards

Recovery from the biopsy itself is usually quick, but the main 'afterwards' is the wait for laboratory results. Some biopsies, especially of the lung or deep organs, need a few hours of monitoring before you go home and a quiet day or two afterwards.

First few hours

You rest while the puncture site settles. After a lung or deep-organ biopsy you are monitored, and a chest X-ray may be done after a lung biopsy to check for any air leak.

Same day

Most people go home the same day. The local anaesthetic wears off over a few hours and the area may ache; simple pain relief usually helps.

Days 1–3

Bruising and soreness settle. You can usually return to light activity, avoiding heavy lifting or strenuous exercise as advised, especially after a deep or chest biopsy.

Up to about 2 weeks

Laboratory results usually come back in this window. You are told who will give you the result and when, and what the next step might be.

What's normal — and not a worry

Mild soreness, bruising or a small bruise at the puncture site
A little aching as the local anaesthetic wears off
Tiredness, especially after a deep-organ biopsy
Waiting and some anxiety before results come back
A small amount of old blood when coughing after a lung biopsy, which usually settles

Aftercare

Rest for the remainder of the day and avoid heavy lifting and strenuous activity as advised.
Keep the puncture site clean and dry; leave the dressing as instructed.
Use simple pain relief if the area aches.
After a lung biopsy, follow the advice given on activity and flying, and seek help promptly if you become breathless.
Restart blood thinners only when and as the team tells you to.
Make sure you know who will give you the results, how and when.
Keep the clinic's contact details to hand in case of bleeding, breathlessness or signs of infection.

Before your procedure

Lift home arranged if sedation, a lung or a deep biopsy is planned
Clear instruction on when to restart blood thinners
Simple pain relief at home
A quiet day or two planned
Confirmation of who gives results, and when
List of urgent warning signs saved
Clinic or out-of-hours contact number saved

Scars and how they heal

An image-guided biopsy is done through a needle puncture, not a surgical cut, so it does not leave a surgical scar. You may have a small dressing and a little bruising or a tiny mark at the puncture site, which usually fades. A core-biopsy needle is slightly thicker than a fine needle but still leaves only a small puncture point rather than a wound that needs stitches.

⚠ Get urgent help if…

Increasing or severe pain at the biopsy site
Bleeding that soaks through the dressing or will not stop
Feeling faint, dizzy or very unwell (possible internal bleeding)
New or worsening breathlessness or chest pain after a lung biopsy — seek urgent help
Coughing up more than a small amount of blood
Fever, chills, spreading redness or pus at the site (possible infection)

Who to contact: your clinician, clinic or test provider first (keep their number to hand). For urgent advice when you can't reach them, call NHS 111. In an emergency, call 999.

General guidance — it doesn't replace the specific advice your radiologist gives you.

Results & realistic expectations

A good biopsy gives the laboratory enough tissue to answer the clinical question — for example whether an area is benign or cancerous, and if cancerous, what type. This information often shapes the whole treatment plan. Results usually take several days to a couple of weeks because tissue has to be processed and examined carefully, and sometimes extra tests are run on the sample.

No biopsy is perfect. A sample can occasionally be inconclusive or fail to capture the abnormal area, so a normal or unclear result does not always completely rule out a problem. If that happens, the biopsy may need to be repeated, done a different way, or followed by more scans. Your team should explain what each possible result would mean and what would happen next.

How long it lasts

A biopsy result reflects the tissue at the time it was taken. It remains useful for diagnosis and planning, but a clear result now does not guarantee that nothing will change in future, and a new or growing abnormality may need a fresh biopsy. For some conditions, repeat sampling is part of ongoing monitoring.

Related tests, treatments or support

A biopsy is usually one step in a larger pathway. It often follows scans such as ultrasound, CT, MRI or PET-CT and is discussed alongside them, frequently at a multidisciplinary team (MDT) meeting. Sometimes fluid is drained or a marker is placed at the same time. The biopsy result is then combined with your scans and clinical picture to plan treatment.

Follow-up & long-term care

You should be told before the biopsy who will give you the result, how and roughly when — often the specialist who arranged it, sometimes at a clinic appointment. Results are commonly reviewed by a multidisciplinary team before being explained to you. You should also know who to contact if you have bleeding, breathlessness or signs of infection in the meantime.

Repeat, follow-on and what comes next

If a sample is inconclusive, the biopsy may need repeating, sometimes with a different technique or more samples.
A clear benign result on a needle biopsy may still be followed by monitoring scans for reassurance.
If a needle biopsy keeps failing to give an answer, a surgical biopsy may be needed.

Ask what happens if the result is unclear or needs repeating, and what is included if further tests or follow-up are needed.

What good aftercare looks like

Clear written instructions on activity, bleeding and (for lung biopsy) breathlessness and flying.
Specific guidance on when to restart blood thinners.
A named contact and urgent-care route for bleeding, breathlessness or infection.
A defined route and timescale for results, usually after multidisciplinary review.
A plan for what happens if the result is inconclusive.

What affects the cost

Costs vary a great deal between people and providers, and we don't publish prices. What matters is understanding what drives the cost and making sure your quote is complete. The main things that affect it:

Which imaging is used to guide the biopsy (ultrasound, CT or MRI)
The body part and how technically difficult and time-consuming the biopsy is
Whether a core biopsy, fine needle aspiration or fluid aspiration is taken, and how many samples
Laboratory (pathology) processing, including any extra or specialist tests on the sample
Monitoring time and any imaging needed afterwards (such as a chest X-ray after a lung biopsy)
The cost of any consultation and the appointment to discuss results

Make sure your written quote includes

The operator's fee and who will perform the biopsy
The imaging and facility fee
The laboratory (pathology) fee, including any additional tests on the sample
How and when results are given, and whether a results appointment is included
What happens, and what it costs, if the biopsy needs repeating because the sample was inconclusive
The cancellation policy
What is covered if you have a complication such as bleeding or a lung collapse

On the NHS? Image-guided biopsies are routinely performed on the NHS as part of investigation and diagnosis; private access is often used for speed or choice of provider.

Frequently asked questions

Does a biopsy treat the problem?

No. A biopsy is a test that takes a sample to help reach a diagnosis. It guides treatment but does not, by itself, make you better.

Will it leave a scar?

It is done through a needle puncture, not a surgical cut, so there is no surgical scar — just a small dressing and sometimes minor bruising that fades.

How long do results take?

Usually several days to a couple of weeks, because the tissue has to be processed and examined, and sometimes extra tests are needed. You should be told who will give you the result and when.

Is it painful?

Local anaesthetic numbs the area. You may feel pressure or a brief ache, and the site can be sore for a day or two afterwards.

What are the risks?

Mainly bleeding and infection, which depend on the body part. A lung biopsy can cause a partial lung collapse that sometimes needs a chest drain. Your team will explain the risks for your specific biopsy.

What if the sample is not enough to give an answer?

Occasionally a sample is inconclusive and the biopsy needs repeating or doing another way, or further scans are arranged. Your team will explain the next step.
