Brief summary

The purpose of this study is to evaluate the effect of the gluteal vasculature in the prone and jackknife positions.

Detailed description

This is a prospective collection of contrast-enhanced CT images of healthy female volunteers in prone and jackknife positions in order to determine if position impacts gluteal venous vasculature.
