T2 mapping - myocardium
T2 mapping is a magnetic resonance imaging technique used to calculate the T2 times of a certain tissue and display them voxel-vice on a parametric map. It has been used for tissue characterization of the myocardium 1-5 and has been investigated for cartilage 6,7 and other tissues 4.

Article
Cardiac strain imaging
Strain imaging is a cardiac imaging technique that detects ventricular deformation patterns and functional abnormalities before they become obvious as regional wall motion abnormalities on conventional cine imaging or echo. It has become more popular lately due to several technological improveme...

Articular-sided rotator cuff tear
Articular-sided rotator cuff tears are partial-thickness rotator cuff tears extending from the articular side into the rotator cuff.
Epidemiology
Articular-sided rotator cuff tears commonly occur in athletes with overhead activity 1.
They are more common than bursal-sided tears and most commo...
Article
Intrasubstance rotator cuff tear
Intrasubstance rotator cuff tears also known as concealed interstitial delaminations (CID) are concealed partial-thickness rotator cuff tears neither extending to the articular nor the bursal side of the rotator cuff.

Medial collateral ligament bursa
The medial collateral ligament bursa is one of the bursae of the knee with the shape of a vertically expanding compartment located between the superficial and deep portions of the medial collateral ligament 1-5. The bursa is usually located in the middle third of the knee, with the anterior marg...
Article
Myocardial injury
Myocardial injury is defined by an elevation of cardiac troponin values above the 99th percentile upper reference limit. It is considered a prerequisite for the diagnosis of myocardial infarction but also an entity in itself and can arise from non-ischemic or non-cardiac conditions 1,2.
Termino...
