Image-guided therapeutic injections have not been shown to alter patient reported outcome measures [94]. MR Arthrography Hip Direct visualization of articular cartilage is possible on MRI because of its intrinsic excellent soft tissue contrast resolution. Intra-articular administration of contrast can also help with the direct visualization of articular cartilage [89]. MR arthrography has been shown to have high sensitivity and fair specificity of 92.5% and 54.5%, respectively, for the detection of chondral pathology in the setting of FAI [52]. A lower sensitivity for the detection of chondral pathology has been reported for the detection of hip articular cartilage defects in a more generalized group of patients [55]. Assessment of the T2* relaxation time is not affected by the presence of intra-articular gadolinium injection [95], and, although more commonly used for research purposes, T2* may be used to assess cartilage ultrastructure. Chronic Hip Pain MRI Hip Without and With IV Contrast Indirect arthrography falls under the technique of MRI hip with IV contrast. The diagnostic accuracy of indirect MR arthrography has not been widely studied [96], and, as such, there is insufficient literature to support the use of MRI with IV contrast in assessment for the degree of cartilage damage. IV contrast administration can; however, help to demonstrate the degree of enhancing inflamed synovium. Delayed gadolinium-enhanced MRI of cartilage may be useful in assessing the degree of hip cartilage damage, but this is most frequently employed in the research setting [97]. Overall, given the scant literature supporting indirect arthrography, this is a technique that is not often used clinically. MRI Hip Without IV Contrast Direct visualization of articular cartilage is possible on MRI because of its intrinsic excellent soft tissue contrast resolution [89]. MRI can demonstrate the articular cartilage and areas of chondral pathology [18,91,93].
