MRI-Guided Biopsy May Increase Accuracy of PCa Diagnosis
Eur Urol. 2006;50:738-749
MRI-guided biopsy of the prostate may improve the diagnostic accuracy in men with elevated or rising PSA levels following previous negative transrectal ultrasound (TRUS)-guided biopsies, German researchers report.
Aristotelis G. Anastasiadis, MD, and his colleagues at the
“According to our knowledge,” the authors wrote, “this is the largest cohort of consecutive men to be examined by MRI-guided transrectal biopsy of the prostate in this setting.”
The investigators cautioned that MRI-guided biopsy has limitations. For example, chronic prostatitis has similar morphologic patterns to cancerous lesions. In addition, the proper placement of the needle guide is time consuming because it has to be identified first on a localizer image. “Then, imaging in two planes perpendicular to each other must be planned and performed.” Furthermore, a good interdisciplinary cooperation between the urologist and uroradiologist is important for optimal diagnostic performance.
