“…Of these, one study used a 3-Tesla (T) field strength magnet [ 14 ], while the other 4 studies evaluated MRI using a 1.5-T magnet [ 12 , 13 , 29 , 35 ]. Fifteen studies evaluated the diagnostic test accuracy of dMRA, this was done with a 1.0-T magnet in 1 study [ 15 ], 1.5-T magnet in 11 studies [ 12 , 13 , 16 , 30 , 32 – 34 , 36 – 39 ] and 3 T magnet in 2 studies [ 14 , 31 ] and the field strength of the MRI machine was not stated in one study [ 17 ]. Five studies assessed the diagnostic test accuracy of iMRA one with 3 T magnet [ 21 ] and the others with 1.5 T magnet [ 27 , 28 , 35 , 40 ].…”

BackgroundSeveral types of Magnetic resonance imaging (MRI) are commonly used in imaging of femoroacetabular impingement (FAI), however till now there are no clear protocols and recommendations for each type. The aim of this meta-analysis is to detect the accuracy of conventional magnetic resonance imaging (cMRI), direct magnetic resonance arthrography (dMRA) and indirect magnetic resonance arthrography (iMRA) in the diagnosis of chondral and labral lesions in femoroacetabular impingement (FAI).MethodsA literature search was finalized on the 17th of May 2016 to collect all studies identifying the accuracy of cMRI, dMRA and iMRA in diagnosing chondral and labral lesions associated with FAI using surgical results (arthroscopic or open) as a reference test. Pooled sensitivity and specificity with 95% confidence intervals using a random-effects meta-analysis for MRI, dMRA and iMRA were calculated also area under receiver operating characteristic (ROC) curve (AUC) was retrieved whenever possible where AUC is equivocal to diagnostic accuracy.ResultsThe search yielded 192 publications which were reviewed according inclusion and exclusion criteria then 21 studies fulfilled the eligibility criteria for the qualitative analysis with a total number of 828 cases, lastly 12 studies were included in the quantitative meta-analysis.Meta-analysis showed that as regard labral lesions the pooled sensitivity, specificity and AUC for cMRI were 0.864, 0.833 and 0.88 and for dMRA were 0.91, 0.58 and 0.92. While in chondral lesions the pooled sensitivity, specificity and AUC for cMRI were 0.76, 0.72 and 0.75 and for dMRA were 0.75, 0.79 and 0.83, while for iMRA were sensitivity of 0.722 and specificity of 0.917.ConclusionsThe present meta-analysis showed that the diagnostic test accuracy was superior for dMRA when compared with cMRI for detection of labral and chondral lesions.The diagnostic test accuracy was superior for labral lesions when compared with chondral lesions in both cMRI and dMRA. Promising results are obtained concerning iMRA but further studies still needed to fully assess its diagnostic accuracy.Electronic supplementary materialThe online version of this article (doi:10.1186/s12891-017-1443-2) contains supplementary material, which is available to authorized users.

“…The reference standard for these studies would thus be the more imprecise MRI/MRA. Although the diagnostic accuracy of MRI/MRA currently is limited,13 limiting image reading to those with specialist training,83 utilisation of precise, tailored protocols84 and improving imaging technology could afford suitability for MRI/MRA as acceptable reference standards for these participants. Implementation of these tests across this broad continuum of hip participants is paramount to determine their actual clinical utility.…”

“…Our pelvic protocols were similar to the newest non-contrast protocols in resolution, field-of-view, and slice thickness and were able to provide enhancement of joint fluid in many cases [ 3 , 4 , 12 ]. The accuracy of hip MRI has been shown to be dependent on radiologist practice settings [ 25 ] and all scans in our study were evaluated by a pediatric musculoskeletal radiologist at a tertiary academic children’s hospital. To date, the only investigations of asymptomatic teenagers have been included in the results of adults, and all studies included high-level athletes with clear mechanisms by which asymptomatic hip trauma might have been incurred [ 5 , 11 , 12 ].…”

PurposeMagnetic resonance imaging (MRI) is a sensitive, non-invasive modality to diagnose acetabular labral pathology, and the normal variants of the acetabular labrum have been characterized in adults. However, the prevalence of labral pathology in the asymptomatic pediatric population is unknown.MethodsAll pelvic MRIs performed at a large tertiary-care children’s hospital were reviewed during one calendar year (2014). Only patients aged between 2 and 18 years were included, and scans were excluded for hip pain/pathology or technical inadequacy. A blinded pediatric musculoskeletal radiologist read all eligible scans for the presence or absence of a labral tear.ResultsThree hundred and ninety-four pelvic MRIs were screened, and patients were excluded for hip pain/pathology (85 subjects), or technical inadequacy (190 subjects). One hundred and eight subjects (216 hips) met the inclusion criteria and were technically adequate for analysis. Labral tears were visualized in three of 216 (1.4 %) hips (two of the 110 subjects; 1.9 %).ConclusionsThere is a low rate of asymptomatic labral pathology by MRI in pediatric patients. The clinical history remains the means of differentiating real labral pathology from spurious imaging findings.Level of evidence IVCase series (prevalence).
