MRI of the prostate is part of a male pelvic MRI scan. It is often used as a complement to other imaging studies and is highly detailed offering accurate measurements and representation of the prostate itself and the surrounding soft tissue.
It can also be used to target the pelvic bone itself for early detection of degenerative lesions.
Indications for an MRI of the pelvis in males can be as following:
- Suspected inflammatory process
- Confirmation or monitoring of malignancy
- Assess congenital anomalies
- Rule out an inguinal hernia
An inguinal hernia is a weak spot in the muscle layer protecting the internal organs allowing for parts of them to protrude outward and often presents as a soft lump in the groin region. It can also involve the testes.
A histological test is still necessary to determine malignancy with certainty, however recent studies are indicative of the usefulness of a Prostate MRI scan for better identification of patients needing a biopsy.
In some patients visualisation of the prostate on other modalities can prove difficult and they benefit greatly from an MRI scan.
Contrast (dye)
Some symptoms and illnesses can be hard to detect even on a MRI scan and require injection of dye (contrast) before or during the scan.
It is particularly helpful in the following conditions:
- Tumours
- Inflammation
- Blood vessels
- Distinguishing between scar tissue and normal organ tissue
The injection is considered very safe for most and you will complete a safety questionnaire detailing your medical history before. The contrast agent (dye) is Gadolinium based and most of it is removed by your kidneys within the next day.
