Can you diagnosed abdominal aortic aneurysm with a stethoscope w/o x-ray?

Indirectly: The best ways to diagnose an abdominal aortic aneurysm are by ct scan or ultrasound. However, in a thin person, one may palpate a pulsatile mass in the upper mid-abdomen or hear with a stethoscope a bruit, which is turbulent flow within a blood vessel.

No: Physical exam can tell if there pulsatile mass in the abdomen but can miss a lot of aneurysms. Listening with the stethoscope does not help. You need a screening duplex ultrasound. Plain abdominal x-ray is not very helpful unless to much calcium in the aortic wall can suggest an aneurysm.
