MRI OF THE GLENOID LABRUM WITH GROSS ANATOMIC CORRELATION

The objective of this pictorial essay is to illustrate the magnetic re sonance image (MRI) appearance of the glenoid labrum and the perilabra l structures with and without instillation of intraarticular contrast material. Ten cadaveric shoulder specimens underwent axial MRI using v arious MR pulse sequences. The shoulders then were transversely sectio ned, and the gross morphology of the labrum and perilabral structures was evaluated and correlated with the MR images. The contrast-enhanced sequences allowed for improved anatomic visualization of the structur es evaluated.
