Data Trace Editor – Discussion: – used to evaluate capsule of shoulder, & glenoid labrum, subscapularis & long head of the biceps, and the humeral head; – glenoid labrum produces low signal intensity since it is made of fibrous tissue; – used for imaging SLAP and Barkart injury – Hill-Sachs … Read more
– Discussion: – T2 images have a long TR & long TE; – used to distinguish normal from abnormal soft tissues; – tissues w/ short T2 values include ca (cortical bone), ligaments & tendons; – tissues w/ long T2 values include neoplasms, inflammation, … Read more
– Discussion: – T1 images w/ short TR & w/ short TE will provide the best anatomic detail; – T1 imaging is most useful for lesions involving marrow & subQ fat; – T1-weighted imaging also provides the highest signal-to-noise ratio and is therefore optimal for evaluating … Read more
– Discussion: – used to assess impingement syndromes (coronal oblique views) and less often glenoid pathology (transaxial views); – it accurately identifes full-thickness rotator cuff tears; – defects show up with high signal intensity traversing supraspinatus tendon on T2 images; – … Read more
