Cardiac CT scan provides a higher spatial resolution and is helpful in the diagnosis of the causes of cardiac arrest by evaluation of left ventricular volumes, ejection fraction,cardiac mass, anomalous origin of coronary arteries, coronary artery calcification, pulmonary embolism, and aorta dissection.

CT scan

Cardiac CT scan provides a higher spatial resolution and is helpful helpful in the diagnosis of the causes of cardiac arrest by evaluation of the following: [1]
