Technique Using MRI And Ultrasound Allows for More Reliable Diagnosis of Prostate Cancer, Study Shows
Combining two imaging techniques to create a 3-D image of the prostate may greatly improve a specialist's ability to view and judge suspicious areas, and determine whether and where prostate cancer may be evident, according to a study published in Urologic Oncology. The study, "Magnetic resonance/transrectal ultrasound fusion biopsy of the prostate compared to systematic 12-core biopsy for the diagnosis and characterization of prostate cancer: multi-institutional retrospective analysis of 389 patients," combines magnetic resonance imaging (MRI) images with transrectal ultrasound (TRUS), creating a fusion biopsy technique called MRI-TRUS that helps to more accurately identify potential anomalies in the prostate and choose which specific part of the tissue should be analyzed for the presence of cancer. Prostate cancer is generally suspected by analyzing of PSA levels in biopsies. The MRI-TRUS procedure has been shown to find more cancer cases, and to distinguish between dangerous and less aggressive tumors. The MRI-TRUS technique requires special imaging equipment and the collaborative work of radiologists and urologists, who receive high-level training before using the equipment. In this procedure, patients at risk of prostate cancer undergo an MRI examination to look for potential anomalies and, if any are detected, MRI images are sent to a device that combines them with ultrasound images. The final 3-D image helps physicians choose if a biopsy is necessary and the location biopsy tissue should be taken from for fur
