Rotator Cuff Tears: Prospective
Comparison of MR Imaging with
Arthrography, Sonography, and Surgery
D. Lawrence Burk, Thirty-eight patients with suspected rotator cuff tears were examined at T by
David Karasick1 using a loop-gap resonator surface coil. The MR findings pared prospectively
Alfred B. Kurtz1 in a blinded fashion with the results from double-contrast arthrography in all 38 patients,
Donald G. Mitchell1 high-resolution sonography in 23 patients, and surgery in 16 patients. In the total group
of 38 patients, MR imaging detected 22 of 22 tears and 14 of 16 intact cuffs as determined

by arthrography. In the 16 surgically proved cases, MR and arthrography showed
Cynthia L. Miller1 identical results, with 92% sensitivity in the diagnosis of 12 tears and 100% specificity
David W. Levy1 in the diagnosis of four intact cuffs. In a subgroup of 23 patients, sonography detected
John M. Fenlin2 nine of 15 tears and seven of eight intact cuffs as determined parison with
Arthur R. Bartolozzi2 arthrography. In 10 surgically proved cases, sonography was 63% sensitive in the
diagnosis of eight rotator cuff tears and 50% specific in the diagnosis of two intact
cuffs.
For the diagnosis of rotator cuff tears, MR imaging parable to arthrography in
both sensitivity and specificity. In this study, sonography was not as accu
