CT Chest and Abdomen With IV Contrast There is no relevant literature regarding venous phase CT chest and abdomen for the follow-up of known thoracoabdominal aneurysm or dissection because most follow-up imaging uses an arterially timed contrast bolus in the form of a CTA (discussed below). Compared with CT of the chest, abdomen, and pelvis, exclusion of the pelvis may result in incomplete evaluation of the extent of aortic pathology. If venous phase or unenhanced CT has already been performed, additional imaging with CTA may not be required in some patients. CT Chest and Abdomen Without and With IV Contrast There is no relevant literature regarding CT chest and abdomen without and with IV contrast for the follow-up of known thoracoabdominal aneurysm or dissection because most follow-up imaging uses an arterially timed contrast bolus in the form of a CTA (discussed below). Compared with CT of the chest, abdomen, and pelvis, exclusion of the pelvis may result in incomplete evaluation of the extent of aortic pathology.

If venous phase or unenhanced CT has already been performed, additional imaging with CTA may not be required in some patients. CTA Chest, Abdomen, and Pelvis With IV Contrast CTA of the chest, abdomen, and pelvis with IV contrast uses fast acquisition times to allow for rapid evaluation of the aorta and diagnosis of pathology.
