Coronary Angiography
Patient first undergo standard coronary angiography(SA) of either left or right coronary system followed by dual-axis rotational coronary angiography(DARCA). The SA protocol consist of six different projections (right anterior oblique (RAO)-caudal, RAO-cranial (CRA), left anterior oblique (LAO)-CRA, LAO-caudal (CAU), antero-posterior (AP)-CRA and AP-CAU) for left coronary artery (LCA) and two projections (LAO and AP-cranial) for right coronary artery (RCA). The DARCA protocol consist of two coronary acquisitions specified by the protocol: one for LCA (Swing LCA CRA 35 5.8s), another for RCA (Swing RCA AP 4.0s).
