Acetabular Labral Tear | Radsource
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.
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.
The imaging evaluation of acetabular labral lesions
2021年8月6日 · Magnetic resonance arthrography (MRA) has been recognized as the gold-standard tool for labral tears but is limited by its invasiveness and radiation exposure. Therefore, MRA has been gradually replaced by convenience and noninvasive magnetic resonance imaging (MRI), which has a diagnostic value that is not as satisfactory as that of MRA.
Hip Anatomic Variants That May Mimic Abnormalities at MRI: Labral …
2013年8月23日 · Normal anatomic variants of the acetabular labrum are observed on MR images and include labral variants, several sublabral sulci, and perilabral sulcus. Because variants can be misidentified as labral abnormalities such as labral tears, the radiologist needs to avoid the pitfall of mistaking variants as abnormalities. CONCLUSION.
Hip Capsulolabral Complex: Anatomy, Disease, MRI Features, and ...
2024年2月1日 · Using a simplified version of a common surgical grading scale for acetabular labral tears improves the utility of preoperative hip MRI for femoroacetabular impingement. Skeletal Radiol 2020 ;49(12):1987–1994.
Acetabular labral tear with paralabral cyst | Radiology Case ...
The non-arthrographic oblique axial MR imaging of right hip reveals a complete anterior acetabular labral tear with labro-osseous separation and a 2.0 cm paralabral lobulated cyst.
Update on MR Imaging of the Acetabular Labrum
2024年6月4日 · Acetabular labral tears are a mechanical cause of hip pain. Hip MR imaging should be performed on 3T magnets using small field of view and high-resolution imaging. If using a lower strength magnet, direct arthrography should be performed.
MR Imaging of the Hip (Part I): Normal Labrum, Labral Tears, and ...
Histologically, three separate layers are identified within the labrum: a randomly oriented fibrocartilaginous layer at the articular surface, a central lamellar layer of collagen, and a circumferentially oriented layer along the capsular surface.
The diagnostic accuracy of acetabular labral tears using magnetic ...
This review concluded that both magnetic resonance imaging (MRI) and magnetic resonance arthrography (MRA) may be useful adjuncts in the diagnosis of hip acetabular labral tears in adults, although MRA appeared superior to conventional MRI.
Magnetic Resonance Imaging of the Hip | SpringerLink
2021年12月29日 · Incorporation of hip magnetic resonance imaging (MRI) into clinical practice can confirm suspected pathology, separate differential diagnoses, and direct treatment plans when dealing with complex pathology involving the hip joint and surrounding structures.
