October 6, 2008 Diagnostic Imaging. MRI reliably characterizes medial meniscal tears -------------------------------------------------------------------------------- Studies from Korea and the U.S. show that MR imaging of the knee is a reliable and accurate test for the detection of specific subtypes of medial meniscal tears. MRI could also help identify false-positive injuries of the menisci and avoid unnecessary surgeries. Dr. So Yeon Lee and colleagues at the Catholic University of Korea…
