Did you know that Radiology Associates Imaging offers a prostate imaging exam that can detect prostate cancer that is missed by biopsy?
Take a look at the images below:
This patient had an elevated PSA value and negative ultrasound-guided prostate biopsy. After the MRI showed an abnormality (arrows) suspicious for prostate cancer in the central gland, the Urologist performed a repeat biopsy targeted to the area of interest. Pathology demonstrated prostate adenocarcioma.
“The patient’s urologist was concerned with the rising PSA value and he understood that even though the biopsy results were negative, that doesn’t guarantee that there isn’t a cancer present,” states Dr. John Gianini. Dr. Gianini is one of our Radiologists who is fellowship trained in Abdominal Imaging, which is a field dedicated to imaging the gastrointestinal and genitourinary systems. He adds, “With a standard 12 sample prostate biopsy only a small portion of the prostate gland is evaluated, especially in men with enlarged prostates. This results in the possibility of missed cancers that may be clinically significant.” More Urologists are now considering prostate MRI as a complementary exam to the PSA blood test and prostate gland biopsy in patients with persistently rising PSA values.
Prostate MRI is performed on one of our high-field strength 3 Tesla MRI units using state-of-art technology. “Since we are using a 3 Tesla scanner, we are able to perform the exam without the use of an endorectal coil,” Dr. Gianini explains, “Also it allows us to perform high quality functional imaging including perfusion, diffusion, and spectroscopy. The patients are getting the highest quality exam available.”
As this case highlights, prostate MRI has become more relevant in the diagnosis and management of prostate cancer. Its precise role in the work-up of prostate cancer is still being defined through research but may be helpful in the following setting:
- Elevated PSA with negative biopsy
- Staging for biopsy proven prostate cancer
- Radiation therapy treatment planning
- Detection of local recurrence after treatment
We will soon have more information on prostate MRI on our website. If you have any questions, you can reach Dr. Gianini via email at firstname.lastname@example.org .
