Editor-In-Chief: C. Michael Gibson, M.S., M.D. [1]
CT Scanning
- CT scanning is not recommended as a screening tool in the asymptomatic patient
- A negative CT scan in a patient with a low pre test probability of disease has a high negative predictive value in excluding the presence of CAD
- CT of stented patients can be difficult to interpret due ot bloassoming artifact
- CT is useful in the assessment of sapehanous vein graft patency
MRI
- Useful in the differentiation of myocarditis (subepicardial pattern) from myocardial infarction (subendocardial pattern)
- Useful in the assessment of pericardial thickening in the assessment of contstrictive pericarditis
- Useful in the assessment of myocardium in the assessment of fibrosis in hypertrophic obstructive cardiomyopathy (HOCM)
- Useful in the assessment of hemochromatosis and to follow magnitude of iron overload
Angiography
- Alone assess coronary lumen
- Inaccurate and variable in the assessment of short, diffusely diseased left main lesions
