“…This result is comparable to the direct method. Sensitivity and specificity in diagnosing tears of the glenoid labra in another study were 91 % and 92 % respectively [9], again superior to conventional MRI and only slightly inferior to the reported results of direct MR arthrography (Fig. 5).…”

Indirect MR arthrography is a relatively new MR technique improving articular and periarticular contrast. It is achieved by injection of paramagnetic MR contrast media intravenously instead of intra-articular injection as in direct MR arthrography. After the injection exercising the joint results in considerable signal intensity increase within the joint cavity. Fat saturated MR sequences then yield arthrographic images. The method is less invasive than direct MR arthrography and first results showed comparable sensitivities and specificities for rotator cuff and glenoid labrum pathology. In this article the technique, established and potential future indications, drawbacks and limitations of the method are reviewed.

“…As the intra-articular injection of contrast renders a noninvasive test invasive, there are some reports where indirect MR arthrography is recommended over direct MR arthrography of the glenohumeral joint [42,43]. Intravenously administered gadolinium-based contrast agents enhance the joint cavity, and this effect is pronounced following active or passive exercise of the affected joint; however, indirect MR arthrography should be combined with frequency-selective fat-saturated T1-weighted imaging, a technique that is not possible on low-field MR units [44].…”

“…Die Sensitivität von Labrumrissen ließ sich gegenüber der nativen MRT durch die indirekte MRA von 79 auf 90 %, von einer Arbeitsgruppe sogar von 70 auf 100 % steigern [8,9]. Das Hauptproblem der indirekten MRA stellt jedoch die hohe Anzahl von falsch positiven Befunden mit einer Spezifität von 71,4 % dar [8].…”
