The right posterior oblique (RPO) is the most helpful aortographic projection for demonstrating the origins of the renal arteries. In 59% of the 692 hypertensive patients studied, the origins of both renal arteries were seen in this projection. The second most helpful aortographic projection was the anteroposterior (AP) view, which showed the origins of the renal arteries in 22.6% of these patients. The remaining 18.4% of the patients required both the AP and RPO projections in order to show the origins of both renal arteries.
右后斜位（RPO）是用于显示肾动脉起源的最有用的主动脉造影投照体位。在692例接受研究的高血压患者中，59%的患者在此投照体位下可显示双侧肾动脉的起源。第二有用的主动脉造影投照体位是前后位（AP），在这些患者中有22.6%在此体位下可显示肾动脉起源。其余18.4%的患者需要AP位和RPO位投照才能显示双侧肾动脉的起源。
