Fig. 9

Cardiomyopathy resulting in poor contrast opacification of the left atrium, left ventricle and aorta on a thoracic CTA being obtained to evaluate for pulmonary embolism on a 64 slice CT. CECT demonstrates excellent opacification of the right heart, but poor opacification in the left heart related to prolonged pulmonary circulation time in a patient with left ventricular systolic dysfunction. BNP was immediately obtained and was elevated at 23,000, echocardiogram obtained within the next 4 h demonstrated a left ventricle EF of 22 %
