Can a CT scan detect brain aneurysms?

CT angiogram: A regular ct scan might detect a large aneurysm with calcium. A test that is designed specifically to look for aneurysms is the ct angiogram. With this test contrast goes into the vessels of the brain. If there is an aneurysm that is larger than 2 mm, it should be detected with this technique.
