Purpose: This study compared 3D-T1 high resolution isovolumetric examination (3DTHRIVE) multiplanar reconstruction (MPR) imaging of shoulder magnetic resonance arthrography (MRA) with conventional MR images and validated the diagnostic agreements of isovolumetric MRA with and without compressed sensing (CS). Materials and Methods: Seventy-three patients who underwent shoulder MRA, including image sets of conventional 2D fast spin echo (FSE) sequences and isotropic 3D-THRIVE sequences with and without CS, were evaluated. The CS acceleration factor was set to 1.5. In the first session, MPR images on the 3D-THRIVE sequence with CS were analyzed using current standard 2D FSE sequences in the axial, oblique-coronal, and oblique-sagittal planes. In the second session, 3D-THRIVE sequences with and without CS were compared with respect to image quality and degree of artifacts. Overall image quality scores and artifacts for conventional 2D images and 3D-THRIVE MPR with CS were analyzed using a paired t-test. The diagnostic agreement for pathological lesions of the shoulder in 3DTHRIVE with and without CS was evaluated using intraclass correlation coefficients. Results: CS in the isotropic 3D-THRIVE showed a reduction in scanning time from 104 s (non-CS) to 81 s (CS). The diagnostic agreement between 2D FSE and 3D-THRIVE for shoulder tendon pathologies was excellent for subscapularis, supraspinatus, infraspinatus, and biceps tendons. The inter-rater agreements were excellent, and CS-3D-THRIVE demonstrated excellent diagnostic agreement for certain tendon pathologies compared with 3D-THRIVE without CS. Conclusion: CS-accelerated isotropic 3D-THRIVE shoulder MRA can provide diagnostically acceptable images of tendon pathology with a reduced scan time. Shoulder MRI using 3D-THRIVE with CS may replace standard 2D FSE sequences in patients who require rapid imaging.
