abstract
- The objective of this pictorial essay is to illustrate the magnetic resonance image (MRI) appearance of the glenoid labrum and the perilabral structures with and without instillation of intraarticular contrast material. Ten cadaveric shoulder specimens underwent axial MRI using various MR pulse sequences. The shoulders then were transversely sectioned, 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 structures evaluated.
