I'm a curious person, I've never had any medical training, but I wish to know some more about aneurysms. Aneurysms are basically weakened spots in the elastic artery wall. This can eventually result in a blood-filled balloon bulging from the artery wall due to the high blood pressure in these vessels. Aneurysms can rupture and this can lead to brain damage when it occurs in the brain. Aneurysms can be detected by injecting contrast material into the bloodstream and making an X-ray (called an angiogram). Now I was reading a wikipedia article about aneurysms where I saw the following picture of an angiogram where reportedly an aneurysm should be visble:
Now, as I said, I know nothing about biology so I would really appreciate it if someone could download the picture and reupload it with the aneurysm circled.
Is it the really dark spot or the big soft spot to the right? Thanks!
