MRI-guided prostate biopsies are performed to collect tissue samples from the prostate gland for examination by a pathologist to determine whether or not the tissue is cancerous.
By utilising MRI imaging, this provides more detailed images of the prostate than is possible with ultrasound.
When Is This Procedure Conducted?
An MRI guided prostate biopsy is currently the only way to accurately diagnose prostate cancer. It also helps differentiate cancer from benign prostatic hyperplasia or nodular enlargement of the prostate, a very common condition in middle-aged and older men that requires a different treatment approach than that of cancer.
MRI-guided prostate biopsy may be used in patients who have a rising PSA level, yet a negative ultrasound-guided biopsy. It also may be used in situations where a diagnostic prostate MRI performed due to rising PSA demonstrates a very small abnormality that may not be easily targeted by ultrasound. MRI is also useful in patients who have previously undergone a biopsy and want to improve the sensitivity of the procedure and the precision of the biopsy.
A biopsy not only detects cancer; it also provides information on the aggressiveness of the cancer and helps to guide treatment decisions.
How Does This Procedure Work?
An interventional radiologist will perform the MRI-guided procedure. You may receive antibiotics, sedatives and pain medication before the biopsy.
The MRI-guided procedure may use contrast material to further aid in the detection or diagnosis of potential abnormalities. The interventional radiologist will insert an intravenous (IV) catheter into a vein in your hand or arm. For an MRI-guided trans rectal biopsy, you will lie face-down on a cushioned table. After the biopsy guide is gently inserted into the rectum, the biopsy needle will be guided into position with the help of the MR images and the biopsy sample will be acquired.
For a MRI-guided trans perineal biopsy, you will lie on your back and a guidance grid will be placed between your legs. Under imaging guidance, the biopsy needle is advanced through the guidance grid into the targeted prostate tissue. MRI-guided biopsies may require two to 14 biopsy samples, depending on whether a focal area is targeted or a mapping biopsy is being performed. The MRI-guided prostate biopsy takes 30 to 90 minutes, with post-procedure monitoring for 45 to 60 minutes.
How Will I Feel After The Procedure?
If you have selected to be sedated for the procedure, you may feel a bit drowsy and you will require someone to drive you home.
You will need to rest for the remainder of the day and will be able to resume normal activities the next day.
How Successful Is MRI Guided Prostate Biopsy?
An MRI-Guided Biopsy is highly targeted to select tissue revealed by the MRI imaging. That means physicians and patients have the confidence that any tissue samples come from locations identified as having the most likely chance of containing cancer.
Summary of Benefits Of MRI Guided Prostate Biopsy?
- MRI-guided prostate biopsies help accurately diagnose abnormalities in the prostate and speed the initiation of appropriate treatment.
- Biopsies help distinguish between cancer and benign prostatic hyperplasia BPH.
- Recovery time for both procedures is brief and patients can soon resume their usual activities.
- MRI images of the prostate provide clearer and more detailed images than with other imaging methods, making it a valuable tool in early diagnosis and evaluation of the extent of tumors.
