Which of the following are true regarding MRI and heart disease?
a) Infarcted myocardium is typically high signal on T2-weighted imaging
b) There is marked enhancement of infarcted myocardium following intravenous gadolinium contrast
c) The cardiac valves are well demonstrated on MRI
d) In acute myocardial Infarction, systolic wall thickening is reduced
e) Viable myocardium may be differentiated from infarcted tissue
A. Infarcted myocardium is typically high signal on T2-weighted imaging
B. There is marked enhancement of infarcted myocardium following intravenous gadolinium contrast
D. In acute myocardial infarction, systolic wall thickening is reduced
E. Viable myocardium may be differentiated from infarcted tissue
C. The cardiac valves are not typically well demonstrated on MRI (This statement is incorrect; cardiac valves are generally better visualized using other imaging modalities like echocardiography.)
