Anti-FLEX: Flexed Levering of Gluteal Vessels

Study Overview
=================
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.

Official Title
-----------------
Anti-FLEX: Flexed Levering of Gluteal Vessels on OR Table May Lead to Extreme Danger During Gluteal Augmentation With Lipoaspirate, a Radio-graphically Studied Position of Superior and Inferior Gluteal Vessels During Flexion of OR Table or Jack-knife Position, Danger Zone.

Conditions
-----------------
Healthy

Intervention / Treatment
-----------------
* Diagnostic Test: CT imaging
