Pattern of cardiac enhancement

Pattern of cardiac enhancement

1-Sub endocardial enhancement:

-Which could be focal or diffuse.

-Focal enhancement include part of the subendocardium while the diffuse include the whole endocardium.

-Causes of focal enhancement are either subendocardial infarction is including only subendocardial layer or trans mural if including with it the mural layer.

-Causes of diffuse enhancement are either amyloidosis or systemic sclerosis.

2-Mid wall enhancement:

-Which could be patchy or linear.

-Linear could be thin or thick.

-Causes of patchy mid wall enhancement are HOCM and right ventricular overflow.

-Causes of linear thin enhancement are idiopathic dilated cardiomyopathy and myocarditis.

-Causes of thick linear enhancement are myocarditis in addition to the following mnemonic

S A C

Where S---Sarcoidosis.

          A---Anderson-Fabry.

          C---Chagas.

3-Epicardial enhancement:

Are myocarditis in addition to the following mnemonic

S A C

Where S---Sarcoidosis.

          A---Anderson-Fabry.

          C---Chagas.
