Sensitivity and Specificity of MRIs in the Identification of Hip Labral ...
Six hundred four (604) patients underwent a labral tear between January of 2017 and May of 2019, 200 subjects did not fit the study criteria resulting in 404 subjects being enrolled in this study. Of those, 128 were male and 276 were female. The radiologists identified 217 true positives, 1 false positive, 184 false negatives, and 2 true negatives.
Acetabular Labral Tears and Cartilage Lesions of the Hip ... - AJR
Arthroscopy did not reveal a labral tear; hence, this was a false-positive result. The results of this preliminary study reveal that indirect MR arthrography shows significant potential in the assessment of chronic hip pain in patients suspected of having labral abnormalities, and appears to provide information similar to that provided by ...
Reliability of Conventional Hip MRI in Detecting Labral Tear and ...
Labral tear was detected in 100% of patients, 97% had an anterosuperior labral tear. 82% of patients had partial thickness cartilage lesions and 8% had full thickness cartilage lesions. MRI had a sensitivity of 100% compared to hip arthroscopy in detecting labral tear, 60% in detecting cartilage erosion.
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.
A comprehensive review of hip labral tears - PMC - PubMed …
These studies demonstrate that a negative scan does not fully rule out a labral tear and that hip arthroscopy remains the gold standard . A potential pitfall in diagnosing labral tears is false positives, such as those which may occur when there is …
Treating Hip Labrum Abnormality and Tears | Jackson Clinics
When it comes to diagnosing hip labrum issues, MRI scans are often used. But here’s the catch: Diagnosing a hip labrum abnormality or tear is difficult, as MRI scans produce an enormous number of false positives. In a 2012 study conducted in Colorado, 73% of 45 asymptomatic individuals tested positive for abnormalities.
The diagnostic performance of non-contrast 3-Tesla
2017年3月1日 · The 3-T non-contrast MRI identified forty-two of the forty-three arthroscopically proven tears at the labral-chondral transitional zone (sensitivity, 97.7%; specificity, 100%; positive predictive value (PPV), 100%; negative predictive value (NPV), 87.5%; accuracy 98%).
Normal anatomical variants of the labrum of the hip at magnetic ...
2012年12月18日 · It has been shown that both conventional magnetic resonance imaging (MRI) and MR arthrography (MRA) (MRI performed after intra-articular injection of a gadolinium-based contrast agent) at field strengths of 0.5-3.0 Tesla (T) achieve moderate sensitivity and specificity in detecting labral tears when compared to either arthroscopic or open surgic...
Diagnostic value of magnetic resonance imaging and magnetic …
2023年3月3日 · MRI has high diagnostic efficacy for acetabular labral tears, and MRA has even higher diagnostic efficacy. Due to the limited quality and quantity of the included studies, the above results should be further validated. Keywords: acetabular labral tears, diagnosis, magnetic resonance arthrography, magnetic resonance imaging, meta-analysis. 1.
Hip labral tears: what you need to know and what your doctor won…
In other words, if you do multiple tests with high false positive rates on a patient with no labral tear, you have a 100% chance of a false positive. This is crucial to understand. MRI or MRA have high false positive rates.
