Abstract: Twelve healthy volunteers underwent ECG-triggered non-contrast-enhanced magnetic resonance venography(NCE-MRV)of lower extremities on a 1.5T MR scanner.Image quality was assessed quantitatively and qualitatively with a 17-segment model.ECG-triggered (NCE-MRV) was successfully performed in all patients.Mean signal to noise ratio and contrast to noise ratio of lower extremities were 66 ± 23 and 53 ± 22 respectively.Excellent and good image qualities were achieved in 62％ and 31％ of all segments respectively without non-evaluable segment.Thus ECG-triggered NCE-MRV of lower extremities is feasible with reliable image quality.
