Which is best for plaque morphology

Ans. is 'a' i.e., CCTA Coronary lesions prone to rupture have a distinct morphology compared with stable plaques, and provide a unique oppounity for noninvasive imaging to identify vulnerable plques before they lead to clinical events. This can be achieved using a non-invasive cardiac imaging using coronary CT angiography. o Large plaque volume, low CT attenuation, napkin-ring sign, positive re-moedlling, and spotty calcification are all associated with a high risk of acute cardiovascular events in patients. Intravascular USG can give comparable results but is an invasive test
