MRI of Labral and Chondral Lesions of the Hip - AJR
2015年8月21日 · Although the current evidence favors the use of MR arthrography, we have found that optimized high-resolution nonarthrographic 3-T MRI of the hip can be highly accurate in detection of chondral and labral abnormalities of the hip.
These suggestions are general guidelines that apply to the use of contrast for MRI exams provided at Oregon Imaging Centers. If you have questions about ordering your patient’s MRI, we encourage you to speak with a radiologist about the study and the need for contrast. * After less than 30 GFR, please consult with a radiologist if indicated.

MR imaging of the hip is best if performed on 1.5-T or 3T magnets using small fields-of-view and high-resolution imaging. Ziegert and colleagues 18 found the axial oblique plane to have the highest detection rate of arthroscopically proven acetabular labral tears and more than 95% of tears were identified with the use of 3 imaging planes.
MR arthrography was superior to conventional MRI for detecting labral tears and acetabular cartilage defects and showed a higher interobserver agreement. For femoral cartilage lesions, both modalities yielded comparable results. Sutter et al. Intraarticular Contrast Administration for Hip MRI Musculoskeletal Imaging Original Research
Magnetic resonance imaging of the hip: anatomy and pathology
On MRI, labral tears and detachments typically appear as linear hyperintense signal intensity on fluid-sensitive sequences. MRA is the imaging technique of choice for evaluating the labrum and is most consistent in detecting labral tears and detachments [6,11,44].
Hip MRI: how useful is intraarticular contrast material for evaluating ...
MR arthrography was superior to conventional MRI for detecting labral tears and acetabular cartilage defects and showed a higher interobserver agreement. For femoral cartilage lesions, both modalities yielded comparable results.
3.0 T MRI is more recommended to detect acetabular labral tears …
2022年3月1日 · Subgroup meta-analysis indicated that the Se of 3.0 T MRI was very close to MRA, and the Sp of 3.0 T MRI, ability to correctly detect that a patient does not have a labral tear, was greater compared to MRA.
Hip Labral Tears - Symptoms, Diagnosis, and Treatment Options
A hip labral tear is an injury to the ring of cartilage (labrum) that surrounds the hip socket. The labrum helps stabilize the hip joint, absorbs shock, and maintains joint lubrication. When torn, it can cause pain, instability, and limited movement in the hip.
MR Imaging of the hip: Avoiding pitfalls, identifying normal variants
2018年12月3日 · Meta-analysis data suggest pooled sensitivity and specificity of 66% and 79%, respectively, for conventional MRI in detecting labral tears, compared to 87%–97% and 64% for MR arthrography. 6,7 MR arthrography is also superior for evaluating the articular cartilage, with sensitivities ranges of 71-92% compared to 58–83% for conventional MRI ...
MRI of Labral and Chondral Lesions of the Hip - PubMed
Objective: Unenhanced MRI, indirect MR arthrography, and direct MR arthrography have been used in the radiologic evaluation of patients with suspected labral tears and chondral lesions of the hip. The purpose of this article is to examine the existing evidence for the use of these techniques in patients with hip pain and suspected labral or ...
