Wall motion abnormalities show circular pattern in speckle echocardiography with improved detection using IV contrast [95]. Echocardiography Transthoracic Stress There is no relevant literature to support the use of echocardiography transthoracic stress for the evaluation of nonischemic DCM or idiopathic cardiomyopathy when ischemia has already been excluded. Arteriography Coronary There is no relevant literature to support the use of coronary arteriography for the evaluation of arrhythmogenic cardiomyopathies. Arteriography Coronary with Ventriculography Imaging is initially performed with noninvasive tests such as MRI or CT. However, the 2010 criteria specifies RV angiographic criteria for ARVD, including regional RV akinesia, RV dyskinesia, or RV aneurysm [123]. CT Chest There is no relevant literature to support the use of CT chest for the evaluation of arrhythmogenic cardiomyopathies. CT Coronary Calcium There is no relevant literature to support the use of CT coronary calcium for the evaluation of arrhythmogenic cardiomyopathies. CT Heart Function and Morphology ECG-gated cardiac CT shows wall motion abnormalities and allows quantification of ventricular volumes and function. RV myocardial fat may be seen but is nonspecific. A single study showed that a CT-based scoring system based on fatty tissue, bulging appearance, and dilation of RV had 87% sensitivity, 94.4% specificity, positive predictive value of 87%, negative predictive value of 94.4%, and accuracy of 92.2% for diagnosis of definitive ARVD [127]. CTA Coronary There is no relevant literature to support the use of coronary CTA for the evaluation of arrhythmogenic cardiomyopathies. FDG-PET/CT Heart There is no relevant literature to support the use of FDG-PET/CT for the evaluation of arrhythmogenic cardiomyopathies. MRI Chest There is no relevant literature to support the use of MRI chest for the evaluation of arrhythmogenic cardiomyopathies.
