Our study presents a novel ECG gated first-pass CEMRA sequence which reads out central k-space data during the cardiac resting phase while the overall center of k-space was made to coincide with peak arterial enhancement. The improved data acquisition efficiency of the ECG-gated first-pass CEMRA allowed for high resolution imaging of the entire thorax. We report initial data of ECG-gated first-pass CEMRA in healthy volunteers and patients.
