Accuracy of detection of thrombus with MSCT as compared to IVUS and OCT will be investigated. [ Time Frame: 24 hours ] [ Designated as safety issue: No ]
All imaging methods will be performed in each patient. A 24 hour period is the maximum allowed time gap between MSCT and invasive imaging (OCT/IVUS).
