Figure 5.
Axial (top) and reformatted coronal (bottom) maximum-intensity-projection (MIP) images of NCE renal MRA from protocol (i). MIP images from VS-IR imaging show excellent contrast between arteries and background tissues (a). MIP images from SS-IR imaging without ECG gating show poor depiction of arteries due to insufficient arterial inflow (b). Images from SS-IR with the optimized ECG gating show significantly improved artery visualization except at an inferior segment of the abdominal aorta (arrow in c).
