Purpose
Glenoid labral tears represent an important cause of shoulder pain,
especially in traumatic settings.
Magnetic resonance arthrography (MRA) and computed tomography arthrography (CTA) of the shoulder have been considered comparable as concerns the identification of superior labrum lesions and full thickness rotator cuff tears.
Dual energy CT (DECT) has been recently proposed in musculoskeletal imaging.
DECT features such as the reduction of metal artifacts in operated shoulders,
or the optimized visualization of contrast material injected by choosing the best kV values during post-processing,
could increase the overall diagnostic accuracy with respect to standard CTA.
The purposes of our study were therefore to investigate the diagnostic accuracy values of DE-CTA in detecting glenoid labrum tears,
as compared MRA,
using surgery as the standard of reference.
