Key result
Multiplanar gradient-echo MR imaging revealed that morphologic findings like absence or separation of the labrum were predictive of tears, whereas increased signal intensity was seen in 46% of normal shoulders.
Why the study?
Does multiplanar gradient-echo MR imaging accurately identify glenoid labral tears based on morphology and signal intensity?
Population
37 shoulders of 16 healthy subjects and 19 patients with subsequent surgical evaluation

Morphologic criteria on MPGR MRI may better indicate labral tears than signal intensity; leaves open prospective validation against arthroscopy.

Does multiplanar gradient-echo MR imaging accurately identify glenoid labral tears based on morphology and signal intensity?
Morphologic findings, such as absence or separation of the labrum, are more predictive of labral tears on MPGR MR images than increased intralabral signal intensity.
McCauley et al. (1992) conducted an observational in Glenoid labrum tears (n=35). Multiplanar gradient-echo (MPGR) MR imaging vs. Healthy subjects was evaluated on Morphologic findings and intralabral signal intensity. Multiplanar gradient-echo MR imaging revealed that morphologic findings like absence or separation of the labrum were predictive of tears, whereas increased signal intensity was seen in 46% of normal shoulders.
