Steady‐state free precession MRA of the renal arteries: Breath‐hold and navigator‐gated techniques vs. CE‐MRA

Abstract

Nav SSFP outperformed breath-hold SSFP in measures of image quality and reader confidence. Sensitivity and negative predictive value for detecting RAS with Nav SSFP was perfect, with an acceptable specificity of 85%. This suggests further study is warranted to evaluate Nav SSFP as a noncontrast screening technique for renal artery stenosis.
