Overview

Cardiac CT scanning with angiography (CTA) can be helpful in detecting the complication of heart failure, as well excluding ischemia as a cause of dilated cardiomyopathy (calcium coronary score and myocardial perfusion analysis).

CT scan

Cardiac CT scanning with angiography (CTA) can be useful to:

Diagnose heart failure: by calculating the biventricular volume and ejection fraction with good correlation to echocardiography.
Assessing the regional wall motion (with cine-loop formatting).^[1]
Excluding ischemia as a cause for DCM (Cardiac CTA has a 98% diagnostic sensitivity and 97% specificity in excluding ischemic cardiomyopathy). Also, Myocardial perfusion analysis of the coronary arteries is also beneficial.^[2]

Differential diagnosis of DCM from hypertrophic cardiomyopathy, arrhythmogenic right ventricular dysplasia, and left ventricular noncompaction.^[3]
