1. Most lesions in the knee joint are T2 bright. 2. T2 dark lesions exhibit limited differential possibilities and their location in the knee joint and appearances are characteristic. 3. A diagnostic algorithm should be followed for arrivng at a definitive diagnosis of a T2 dark lesion.  

1. Table of differential diagnosis of T2 dark lesions, such as vacuum phenomenon, blood clot or hemophilia, intraarticular body, discoid meniscus, displaced flap/bucket handle tears of meniscus, meniscal variants (oblique meniscomeniscal ligament, unilateral meniscomeniscal ligament, anterior and posterior transverse meniscomeniscal ligaments), thickened plica, displaced interference screw, particle disease from ACL graft, calcium hydroxyapatite deposition of posterior oblique ligament, gout, PVNS, lipoma arborescence and primary and secondary synovial osteochondromatosis. 2. Quiz format for the diagnosis of these lesions or lesion categories. 3. Diagnostic algorithm with summary of the salient features.
