Ans. (a) Optical Coherene Tomograpghy Ref: Harrison 19th ed. / 270e-4 IOC- IVUS and Best Inv- OCT * Coronary lesions prone to rupture have different morphology compared with stable plaques, and can be evaluated by OCT to identify vulnerable plaques before they lead to clinical events. Large plaque volume, low CT attenuation, napkin-ring sign and spotty calcification are all associated with a high risk of acute cardiovascular events in patients.
