Description
Summary:[...]a rare case of seatbelt injury causing rupture of the deltoid muscle has been diagnosed by MRI.1 A ganglion cyst in the suprascapular fossa is uncommon and can cause a nerve palsy; noncontrast MRI helps diagnosing this pathology and planning of the surgical procedure.2 Bony pathology can be associated with other structures; MRI helps assess the anatomic association of acromioclavicular joint degeneration with supraspinatus outlet impingement.3 Non-contrast MRI has 89% sensitivity and 100% specificity in detecting rotator cufftears; all missed tears were partial thickness tears.4 In a study by Arnold in this issue,5 the sensitivity and specificity of non-contrast MRI in diagnosing full thickness rotator cufftears were 0.91 and 0.98, respectively, whereas the corresponding values for diagnosing labral tears were 0.48 and 0.99. [...]non-contrast MRI was regarded as reliable only for full thickness rotator cufftears and anterior labral tears.
