From: Improved left atrial imaging in atrial fibrillation patients using novel ECG-gated vs. conventional non-gated cardiac MRA

Figure 1

ECG-gated vs. non-gated cardiac MRA patient with atrial fibrillation. Nongated MRA (Image B) suffers from blurring and reduced border sharpness of the left atrial structures and pulmonary veins (blue arrows). In comparison, ECG-gated MRA (Image A) shows better border detail (red arrows) and overall scan quality without a significant loss in SNR and CNR. Images acquired in same atrial fibrillation patient, two days apart.
