520			_aProspective gating on 256-slice CT therefore provides a temporal resolution of 135 ms compared with 210 ms on 64-slice CT, the improvement in temporal resolution results in significantly improved image quality for all coronary vessels and reduction of the motion artifacts. The significant difference between 256-slice MDCT and 64-slice MDCT is that 256-slice MDCT requires only two image acquisition to be combined so reduces the stair-step artifact compared five to eight with 64 MDCT, so, the potential for stair-step artifacts is reduced with prospectively gated axial 256-slice CTCA even with higher heart rates
