Do you prefer CTA or MRA for further imaging in patients with ascending aortic dilatation detected on TTE?

The first question you need to ask yourself is whether or not any further evaluation of the aorta is needed at all. Depending on why the echo was ordered in the first place, the finding of the dilated aorta may be a serendipitous finding unrelated to the indication for the echo, and easily explainab...

For me, the answer depends on the intent of the imaging and the concordance between the visualization of the aorta on echocardiography and CT or MRI. My preference is to do surveillance using echo, but only if echo and MRI or CT are concordant. If I determine that I need to use CT or MRI to visualiz...
