A raised PSA, abnormal prostate examination, or suspicious MRI result can be worrying. For many men, the next question is simple:
“Do I need a prostate biopsy — and if so, which type?”
A prostate biopsy is a procedure used to collect small tissue samples from the prostate so they can be examined by a pathologist. It may be recommended when there is concern about possible prostate cancer or when further investigation is needed after screening, examination or imaging results.
A raised PSA does not automatically mean prostate cancer. PSA levels may also be affected by conditions such as benign prostate enlargement, inflammation, infection, age-related changes, recent procedures or other factors. The NHS notes that a high PSA does not necessarily mean cancer and may be raised for other reasons such as benign prostate enlargement.
Not all prostate biopsies are performed in the same way. Some are systematic, some are targeted and some use MRI information to help guide where tissue samples are taken.
Clinical guidance describes prostate biopsies as either targeted, where MRI is used to identify suspicious areas for sampling or systematic, where samples are taken from different regions of the prostate. In simple terms, some biopsies focus on areas seen on MRI, while others sample several planned areas of the prostate.
This article explains the main prostate biopsy options and how transperineal MRI fusion prostate biopsy may be considered in selected patients.
When might a prostate biopsy be recommended?
A prostate biopsy may be discussed if there are findings that require further investigation, such as:
- A raised PSA blood test
- An abnormal prostate examination
- A suspicious area seen on prostate MRI
- Ongoing concern about prostate cancer
- A previous biopsy that did not provide enough clarity
- Monitoring or reassessment of known prostate concerns
A consultation with a urologist allows these findings to be reviewed in context. This includes looking at the PSA pattern, MRI result, clinical examination, age, medical history, family history, symptoms and any previous prostate investigations.
The goal is not simply to “do a biopsy.” The goal is to decide whether a biopsy is clinically appropriate and if so, which biopsy approach may be suitable.
What are the main prostate biopsy options?
There are different ways a prostate biopsy may be performed. The most appropriate option depends on the patient’s PSA, MRI findings, prostate size, previous biopsy history, general health and clinical risk.
The main biopsy approaches include:
- Standard systematic prostate biopsy
- Transrectal ultrasound-guided biopsy
- MRI-targeted biopsy
- Transperineal prostate biopsy
- Transperineal MRI fusion prostate biopsy
Each approach has a different purpose and method.
A. Standard systematic prostate biopsy
A standard systematic biopsy involves taking tissue samples from several planned areas of the prostate. This approach is designed to sample the prostate broadly.
Systematic biopsy can be useful because it does not rely only on one visible abnormal area. However, because the samples are taken from standard zones, it may not always directly target a specific suspicious lesion seen on MRI.
In some cases, systematic biopsy may be combined with targeted biopsy to improve the overall diagnostic assessment. NICE notes that a systematic biopsy may be done alongside a targeted biopsy in some situations.
2. Transrectal prostate biopsy
A transrectal prostate biopsy is performed through the rectum. A transrectal ultrasound probe is used to image the prostate and biopsy samples are taken through the rectal wall.
This has historically been a common method of prostate biopsy. However, because the needle passes through the rectal wall, infection-related risk is an important consideration.
NICE explains that in a transrectal ultrasound-guided prostate biopsy, samples are collected using a needle inserted through the rectal wall. NICE also notes that some people may develop serious infections, including sepsis requiring hospital admission and antibiotics.
This does not mean transrectal biopsy is never appropriate. It means the route of biopsy should be discussed carefully with the treating urologist.
3. MRI-targeted prostate biopsy
MRI-targeted biopsy uses MRI findings to help identify suspicious areas in the prostate. Tissue samples can then be directed toward those areas.
This differs from a purely systematic biopsy, where samples are taken from standard regions rather than specifically targeting an MRI-visible area.
NICE explains that MRI fusion biopsy systems fuse the MRI image onto the live ultrasound image to assist biopsy targeting. These systems are used for targeted biopsies of suspicious lesions when a small number of tissue samples are taken.
MRI-targeted biopsy may be particularly useful when a prostate MRI has identified a lesion that needs further investigation.
4. Transperineal prostate biopsy
A transperineal prostate biopsy is performed through the perineum, which is the skin area between the scrotum and anus.
This route avoids passing the biopsy needle through the rectal wall. NICE explains that in local anaesthetic transperineal biopsy, the needle enters through the perineum and this route may greatly reduce the risk of biopsy-related sepsis compared with transrectal biopsy.
A transperineal approach may also allow access to areas of the prostate that can be more difficult to sample through some other methods, depending on the patient’s anatomy and the area of concern.
5. Transperineal MRI fusion prostate biopsy
Transperineal MRI fusion prostate biopsy combines two important elements:
MRI targeting and transperineal access.
MRI images are used to identify suspicious areas in the prostate. These MRI images are then fused with live ultrasound guidance during the biopsy to help guide sampling of the area of concern.
Have a look at my service page: describes transperineal MRI fusion prostate biopsy as using MRI sequencing together with ultrasound fusion to help target suspicious prostate lesions. The page also lists benefits of the transperineal approach, including lower infection risk and potential access to anterior parts of the prostate.
This biopsy option may be considered when there is a suspicious MRI finding, a raised PSA with ongoing concern, or when a more targeted biopsy approach is clinically appropriate.
Standard biopsy vs MRI fusion biopsy
A standard systematic biopsy samples multiple regions of the prostate according to a planned pattern.
An MRI fusion biopsy uses MRI information to help target a suspicious area seen on imaging.
The difference is important because some prostate concerns are visible on MRI and targeted biopsy can help direct tissue sampling toward those areas. However, targeted biopsy does not replace clinical judgement. In some patients, the urologist may still recommend combining targeted and systematic sampling.
The most appropriate biopsy strategy depends on the individual patient.
Transrectal vs transperineal biopsy
The key difference is the route used to access the prostate.
| Biopsy route | How it is performed | Key consideration |
| Transrectal biopsy | The biopsy needle passes through the rectal wall. | Common method, but infection-related risk is an important consideration. |
| Transperineal biopsy | The biopsy needle passes through the skin between the scrotum and anus. | May reduce infection-related risk and may allow access to certain areas of the prostate. |
Both approaches may have a role in prostate cancer investigation, but the transperineal route is increasingly discussed because of its infection-risk profile.
Why transperineal MRI fusion biopsy may be considered
Transperineal MRI fusion biopsy may be considered because it can help:
- Target suspicious areas seen on MRI
- Sample the prostate through the transperineal route
- Reduce infection-related concerns compared with the transrectal route
- Access areas of the prostate that may be difficult to reach with some other approaches
- Support clearer diagnostic planning when prostate cancer is a concern
It is important to avoid thinking of any biopsy method as a guaranteed answer. A biopsy is one part of the diagnostic process. The final interpretation depends on the patient’s full clinical picture, PSA pattern, MRI findings, tissue results, and specialist assessment.

What happens after a prostate biopsy?
After the biopsy, the tissue samples are sent to a pathology laboratory for assessment.
The results may show:
- No cancer detected in the sampled tissue
- Inflammation or other benign prostate changes
- Prostate cancer that may require further discussion
- Findings that need monitoring or additional investigation
If prostate cancer is detected, the next step depends on several factors, including the grade, extent of disease, PSA level, MRI findings, age, general health and patient preference.
Not all prostate cancers are treated in the same way. Some may require monitoring, while others may require treatment planning. The biopsy result helps guide that discussion.
When should you speak to a urologist?
You should consider speaking to a urologist if:
- Your PSA is raised
- Your PSA is increasing over time
- Your doctor has found an abnormality on prostate examination
- Your MRI has shown a suspicious prostate lesion
- You have been advised to consider a prostate biopsy
- You want to understand your biopsy options before proceeding
A consultation does not automatically mean you will need a biopsy. It allows your results and risk factors to be reviewed properly.

Frequently Asked Questions
Does a raised PSA always mean prostate cancer?
No. A raised PSA does not automatically mean prostate cancer. PSA may be raised because of benign prostate enlargement, inflammation, infection, age-related changes, or other factors. However, a raised or rising PSA should be assessed by a doctor or urologist.
What is the difference between transrectal and transperineal prostate biopsy?
A transrectal biopsy passes the needle through the rectal wall. A transperineal biopsy passes the needle through the skin between the scrotum and anus. The most suitable approach depends on the patient’s clinical findings and specialist assessment.
What is MRI fusion prostate biopsy?
MRI fusion prostate biopsy uses MRI images together with live ultrasound guidance to help target suspicious areas in the prostate during biopsy.
Is transperineal MRI fusion biopsy suitable for every patient?
No. Suitability depends on the patient’s PSA, MRI findings, examination findings, prostate size, medical history, previous biopsy history, and specialist assessment.
