One other image modality that can be used in diagnosing and treating UA/NSTEMI is CT coronary angiography. This is a superior imaging technique with a sensitivity and specificity of 90% and 95% respectively. If there is no evidence of either calcified or noncalcified plaque on coronary angiogram, then it is highly unlikely that the patient’s symptoms are due to UA/NSTEMI.
