There are a number of tests that can help diagnose an aneurysm.
Physical Exam
When the healthcare provider presses on the abdomen during a physical examination, they may be able to feel an abdominal aortic aneurysm. They may also hear a telltale “rushing” sound in the abdomen with a stethoscope. However, aneurysms often can’t be found during a physical exam. Depending on symptoms, the healthcare provider may recommend other tests.
Health care providers sometimes discover “silent” aneurysms” (without symptoms) during surgery. They may also find one during a test, such as an x-ray, ultrasound, scan, that happens for another reason.
Tests
Ultrasound
This test uses sound waves to create a picture of the inside of the body. It can show an aneurysm and its size.
CT Scan
This test uses x-rays to take pictures of internal organs. The technician will inject dye into a vein that will show up on the x-ray images. This shows the aneurysm’s size and shape. A CT scan gives a more detailed image than an ultrasound.
MRI
Magnetic resonance imaging uses magnets and radio waves to create images of the inside of the body. This test is good at detecting aneurysms and pinpointing their size and exact location.
Angiogram
During this test, the technician injects a special dye into a blood vessel so that it can be seen and examined for problems.
Recommended Screenings
Abdominal Aortic Aneurysm
If you are in either of the two categories below, you need to have an abdominal ultrasound to screen for the presence of an abdominal aortic aneurysm:
- Men at least 60 years old with a family history of abdominal aortic aneurysm.
- Men aged 65 to 75 years who have ever smoked.
There is not enough evidence to recommend that women receive a screening abdominal ultrasound, regardless of smoking history.
Intracranial Aneurysm
If you fall in either of the two categories below, you need to ask your healthcare provider about being screened for intracranial aneurysm:
- Polycystic kidney disease.
- Strong family history (at least 2 family members) of intracranial aneurysm or subarachnoid hemorrhage (these happen in or around the brain).
