Although this study focused on AAA, the result is likely applicable to measurements of thoracoabdominal aneurysm or dissection, with the caveat that the complexity of endovascular thoracoabdominal repair may place a higher value on precise measurements. Similar conclusions were reached by a 2013 study comparing pre-EVAR MRI without IV contrast and CTA [61,74]. MRA Chest and Abdomen Without and With IV Contrast Compared with MRA of the chest, abdomen, and pelvis, exclusion of the pelvis carries the drawback of precluding evaluation of the iliofemoral access vessels if endovascular repair is considered. Furthermore, if the thoracoabdominal dissection or aneurysm extends into the pelvis, a lack of pelvis evaluation could result in incomplete evaluation of the aortic pathology. In select cases with recent imaging of the pelvis or in cases of planned open repair without extension into the pelvic vasculature, further imaging of the pelvis vasculature may not be needed.
