Multi-parametric MRI (mpMRI)
A multi-parametric magnetic resonance imaging (mpMRI) scan of the prostate is a new, extremely precise imaging technique for diagnosing prostate problems. It does not use ionising radiation and is generally able to correctly identify the most aggressive tumours in the prostate, enabling the urologist, where necessary, to take tissue samples from specific areas of the prostate. An mpMRI scan is very often able to differentiate between tumours which are not clinically significant and aggressive cancers, thus enabling the doctor to avoid performing any unnecessary biopsies.
What happens during an MRI scan of the prostate?
An MRI scan of the prostate takes about 25–35 minutes. The patient lies in a comfortable position on his back. Before the scan, the patient will be asked to empty his bladder and will be given medication to reduce movements of the bowel, which can interfere with the images produced by the scan. A flexible cannula will then be inserted into the patient’s arm. During the scan, this cannula will be used to administer an MRI contrast agent. This contrast agent is generally well tolerated. This allows more accurate visualisation of blood flow in the prostate, and allows the doctor to evaluate lymph nodes and other nearby tissue.
During the scan, the MRI scanner will make loud noises. The patient will therefore be provided with headphones and will be able to communicate with the MRI technicians via an intercom.
Patients will usually be told not to have anything to eat or drink for up to four hours before undergoing an MRI scan of the prostate. If a patient has had a biopsy of the prostate, he should wait at least 6 weeks before having an MRI scan, as any bleeding may make interpreting the scan more difficult.
When are mpMRI scans of the prostate used?
The urologist will organise an MRI of the prostate in particular for early detection and diagnosis of prostate cancer in patients who are at increased risk due to a family history of prostate cancer, or following a negative biopsy where the PSA level remains raised. An MRI scan is also useful for planning surgery or radiotherapy. The scan images can also be useful for keeping an eye on known prostate cancer where an active surveillance approach is being taken, for monitoring the effects of treatment, and for following up after treatment. Where raised PSA levels suggest a possible recurrence, an MRI scan of the prostate can yield more detailed information.
MRI of the prostate – benefits at a glance
- rapid, pain-free examination procedure
- does not use x-rays
- produces more reliable images than other cross-sectional imaging techniques, enabling better diagnosis and treatment depending on the size and extent of the cancer
- also allows imaging and further investigation of the pelvic lymph nodes
