What are the clinical indications for cross sectional imaging of the prostate gland and seminal tract?
The most common clinical indication is staging of known prostate cancer diagnosed by previous biopsy, where prostate MRI is used most frequently for this purpose. Other indications include evaluation of patients who have hematospermia or male infertility.
Transrectal ultrasonography (TRUS) and MRI are most often utilized for evaluation of the prostate gland and seminal tract. CT is not very useful for this purpose given its inferior soft tissue contrast resolution compared to TRUS and MRI.
