摘要
Cardioembolic stroke is a potentially devastating condition and tends to have a poor prognosis compared with other ischemic stroke subtypes.Therefore,it is important for proper therapeutic management to identify a cardiac source of embolism in stroke patients.Cardiac computed tomography(CCT)can detect the detailed visualization of various cardiac pathologies in the cardiac chambers,interatrial and interventricular septum,valves,and myocardium with few motion artifacts and few dead angles.Multiphase reconstruction images of the entire cardiac cycle make it possible to demonstrate cardiac structures in a dynamic manner.Consequently,CCT has the ability to provide high-quality information about causal heart disease in cardioembolic stroke.In addition,CCT can simultaneously evaluate obstructive coronary artery disease,which may be helpful in surgical planning in patients who need urgent surgery,such as cardiac tumors or infective endocarditis.This review will introduce the potential clinical applications of CCT in an ischemic stroke population,with a focus on diagnosing cardioembolic sources using CCT.
