 Special Imaging Considerations Several studies have looked for ways to shorten typical shoulder conventional MRI or MR arthrogram protocols while maintaining diagnostic accuracy. Isotropic 3-D imaging has been increasingly used as a substitute for conventional multiplanar 2-D MRI, with a similar sensitivity and specificity for rotator cuff tear and labral abnormalities at a lower scan time [7,8]. Faster scans can also be performed using 2-D fast spin echo sequences with parallel imaging, which produce similar findings as seen on conventional MRI [9].
