After that, an effective coronary improvement search are did, therefore the scanned images was canned and you may processed of the multiple-layer reconstruction (MPR), curved planar repair (CPR), limitation strength projection (MIP), frequency helping to make (VR) and you may aerobic optimization studies software. Max CT photos were used to your review off coronary vascular plaques.

CCTA image study

The fresh coronary blood vessels had been divided in to 16 segments depending on the Western Heart Connection group approach , and you will photographs was analyzed separately of the 2 radiologists involved with cardio imaging medical diagnosis.
