A single-session CT angiography protocol for extracoronary vascular abnormality screening in spontaneous coronary artery dissection (SCAD).

ABSTRACT:

Introduction

Extracoronary vascular abnormalities (EVAs) are common in patients with spontaneous coronary artery dissection (SCAD), and expert consensus statements recommend evaluation with head-to-pelvis cross-sectional imaging. Lack of a universal imaging protocol remains a barrier to consistent implementation of this recommendation. We sought to implement a high-fidelity, single-session, head-to-pelvis computed tomography angiography (CTA) protocol that minimizes radiation and contrast exposure compared to multisession CTA.

Methods

A total of 97 consecutive patients with SCAD were evaluated with a single-session CTA (SS-CTA protocol). The comparison group consisted of 63 consecutive patients who underwent asynchronous CTA of different body segments (MS-CTA). The primary o
