A group of patients who underwent transrectal ultrasound (TRUS)-guided prostate biopsy was compared with a group of patients who, after a previous negative biopsy, were biopsied again using a fusion of magnetic resonance imaging (MRI) and TRUS imaging data (1). The sensitivity of TRUS is only 50%.
There is no mentioning of the fact that bleeding as well as abscess and scar formation may occur in the prostate after biopsies which then can significantly impair the MRI-based detection of prostate cancer.
How easy would it be to have an MRI done prior to the biopsy to assist with biopsy planning. As a “by-product”, the tumor stage could be determined. In addition, lymph nodes and bones are also visualized in the examined area.
However, this is not the way medicine is practiced today.
