This review focuses on the key non-invasive cardiac imaging techniques, including cardiac CT and MRI, and highlights essential publications pertinent to clinicians managing ischemic and non-ischemic cardiomyopathy. Cardiac computed tomography (CT) Provides an anatomical assessment that offers superior diagnostic accuracy compared to functional tests. It is a valuable tool for understanding the impact of non-obstructive coronary artery disease on patient outcomes. Additionally, cardiac CT is beneficial in defining the morphology of vulnerable plaque, which closely aligns with IVUS findings. It also demonstrates safety advantages, including reduced contrast volume and radiation dose and lower risk of contrast-induced nephropathy when used in post-CABG besides conventional coronary angiograms. Cardiac MRI provides invaluable insight into the MI size and microvascular obstruction, critical for understanding a patient’s prognosis. The assessment of scar tissue with CMR has become an essential tool for risk stratification and informs therapeutic decisions regarding the implantation of ICD.
