Abstract
Background: The target of this study was to compare between MR arthrography with parallel planes and MR ar-thrography with radial planes in the diagnosis of acetabular labral tear and chondral lesion of the hip joint.
Patients and Methods: 28 hips of 27 patients with sus-pected labral tear and/or FAI were enrolled in this prospective study. All hips were examined by direct MR arthrography. The acetabular labrum and articular cartilage were assessed at parallel planes (axial and coronal) and compared to radial planes.
Results: Parallel planes detected 14 labral tear and 13 chondral lesion of the 28 examined hips while radial planes detected 22 labral tear and 22 chondral lesion.
Conclusion: Radial planes have higher sensitivity than parallel planes in diagnosis of acetabular labral tear and chondral lesion of the hip.
