Superior Labral Anterior Posterior (SLAP) Lesions of the Glenoid Labrum: Reliability and Accuracy of MR Arthrography for Diagnosis

Abstract

MR arthrography of the shoulder is reliable and accurate for detection of SLAP tears.

Assessment of the rotator cuff and glenoid labrum using an extremity MR system: MR results compared to surgical findings from a multi‐center study

“…Again, this may be related to the particular surgical technique, arthroscopic criteria, or patient population associated with this particular site. Several studies have reported that the use of intraarticular contrast improves the diagnostic capabilities of MR imaging for the glenoid labrum when compared to conventional MR imaging (7,15,16,(32)(33)(34)(35)(36). Therefore, the possibility exists that MR arthrography performed with the extremity MR system may result in increased sensitivity and specificity for tears of the glenoid labrum.…”

“…MAGNETIC RESONANCE (MR) IMAGING is regarded as a useful and accurate technique for diagnosing shoulder disorders, including rotator cuff disease and lesions of the glenoid labrum (1)(2)(3)(4)(5)(6)(7)(8)(9)(10)(11)(12)(13)(14)(15)(16). MR imaging of the shoulder has been predominantly performed by using wholebody MR systems operating at high-field-strengths (1.0 -1.5 Tesla) or, more recently, utilizing low-fieldstrength (0.2-0.35 Tesla) scanners (1)(2)(3)(4)(5)(6)(7)(8)(9)(10)(11)(12)(13)(14)(15)(16).…”

In 2001, Shellock et al (3) studied the diagnostic capabilities of an extremity MR system for identifying shoulder pathology.…”

Prolotherapy: A Non-Invasive Approach to Lesions of the Glenoid Labrum; A Non-Controlled Questionnaire Based Study

“…For MRA, these values increased to 75 and 80 percent [30]. As already discussed, the differentiation between types I, III, and IV SLAP tears can also be problematic, with important consequences for the planning of surgery [28].…”

“…These tears, which are highly associated with rotator cuff lesions [4], are considered of low clinical relevance [27] and surgery for these patients may not be indicated [28]. However, type I SLAP tears are difficult to distinguish from type III and type IV preoperatively [28]. Consequently, inaccurate diagnosis can result in unnecessary arthroscopy.…”
