Patient's exposure to radiation significantly lower when using prospective gated 64-channel cardiac CT

A new cardiac CT technique, prospective gated 64-channel cardiac CT, has a significantly lower radiation dose and produces CT coronary angiograms with better image quality when compared with the standard retrospective ECG gating, according to a recent study conducted by researchers at the University of Washington in Redmond, WA.
