CT is the best modality for determining whether a patient is a candidate for endovascular aneurysm repair (EVAR). It can assess the aneurysm neck diameter, length, and angulation, as well as thrombus within the neck. The CT scan is also useful for assessing iliac vessel diameter, calcification, and tortuosity, which are important for determining whether the endovascular device can be advanced from the femoral artery.
