The results are almost binary. Either you show bone mets or you do not. Not much else to be learned from the MRI. As noted by Fairwind the MRI will not pick up micro metastases. Waste of money if your PSA is fairly low. Mine was 21.5 and nothing showed on the MRI. CT scan was more useful as it showed lymph node swelling in the illiac region indicative of metastasis to the lymph nodes.
