QUIZ 3: Shoulder Imaging


What is the mean goal of T1WS ? :

• A : to analyze the trophicity and /or the fatty degeneration of the muscles of rotator cuff

• B: to find a kyst of spino- glenoid notch• C: to detect a labral tear• D: to detect a adhesive capsulitis



You must use T2W versus PD on coronal plan . Why?

A: to differentiate yellow vs hematopoietic marrowB: to analyse the superieur and inferieur labralC: to avoid the “magic angle “on the tendon of the supra spinatusD: to optimize the “scintigraphic effect “

Parsonage Turner Syndrom


Parsonage Turner syndrome is an acute idiopathic brachial neuritis

Diagnosis is made with a combination of history, EMG (which demonstrates denervation changes, especially of the suprascapular nerve) and imaging

the most frequently involved muscles are supraspinatus and infraspinatus (innervated by suprascapular nerve) followed by deltoid (innervated by axillary nerve)
