KNEE MRI PLICA SUPRAPATELLAR BURSA LIPOHEMARTHROSIS NORMAL SUPRA PATELLAR PLICA The normal supra patellar plica is not continuous. There is a gap in it ( fenestration) which allows fluid to circulate freely in the SP bursa above and below the plica. CONTINUOUS SUPRAPATELLAR PLICA At times the SP Plica is continuous with no gap. Normally

KNEE MRI MENISCUS EXTRUSIONS ARE POINTING YOU TO A ROOT TEAR THE MOST OBVIOUS CAUSE Loss of Joint Space from degeneration and cartilage loss is the most obvious cause. The reduction in joint space results in the meniscus being ” squeezed” out of the joint like toothpaste. BUT…there is another important cause to look for..

SUBACROMIAL SUBDELTOID BURSITIS MRI RADIOLOGY DISCUSSION Subacromial subdeltoid (SASD) bursitis on MRI can have a number of appearances. In this case we have a nodular type of synovitis which should raise the possibility of an inflammatory arthritis as a cause (Rheumatoid Arthritis in this case). WHAT DO WE SEE ON THE IMAGE? Fluid in the

3 LIGAMENTS ATTACHED TO THE CORACOID PROCESS 3 LIGAMENTS ATTACHED TO THE CORACOID PROCESS: There are three ligaments that attach to the coracoid process of the shoulder. When reporting a shoulder MRI they should be part of the overall assessment. So what are they and how do you find them? See the brief video below.
BASILAR INVAGINATION MRI RHEUMATOID ARTHRITIS BASILAR INVAGINATION MRI RHEUMATOID ARTHRITIS MCRAE'S LINE There can be apparent superior migration of the dens to the foramen magnum. It’s apparent because it’s due to cranial settling with the skull base moving down rather than the odontoid moving up. To assess this on imaging, there are a
