misconception in people that having an aneurysm means bleeding in the brain. An aneurysm is in fact a balloon-like swelling in a blood vessel that can affect any large vessel in your body; these larger vessels being arteries. Aneurysms pose a risk to health from the potential for rupture, clotting, or dissecting. It is the pressure of the blood passing through a weak part of the blood vessel that forces it to bulge outwards, forming a sort of a blister. If the sac that is formed extends the artery too far, the vessel may burst, causing death by bleeding. Rupture of an aneurysm in the brain causes stroke, and rupture of an aneurysm in the abdomen causes shock. (THIJ, 2001)
Aneurysms are the cause of many deaths because they are usually silent until a medical emergency occurs. "One author has referred to an AAA as a "U-boat" in the belly, because they are silent, deep, deadly, and detectable by sound waves." (Tilson)
It is extremely difficult to diagnose an aneurysm. Having a thin body and a moderately large sized aneurysm is the ideal conditions in which you or your doctor may be able to detect one. Most of the aneurysms are discovered as a result of medical imaging for other conditions, by ultrasound exams, CAT scans, MRI's, or even plain X-rays of the abdomen. Aneurysms are also detected by physical exam, on a basic chest or stomach X ray, or by using ultrasound. The size and location can be found through echocardiography or radiological imaging, such as arteriography, magnetic resonance imaging (MRI), and computed topography (CT) scanning.
It is very hard to detect aneurysms as their symptoms are not provocative. "Abdominal aortic aneurysms may cause pain or tenderness below your stomach, make you less hungry, or give you an upset stomach. Cerebral (brain) aneurysms may have no symptoms, although you may have headaches, pain in your neck and face, or trouble seeing and talking." (THIJ, 2001)
The treatment of aneurysms depends on the size and location of the aneurysm and the overall health of the patient. "The aneurysms in the upper chest, the ascending aorta are usually operated on right away. Aneurysms in the lower chest and the area below your stomach, the descending and abdominal parts of the aorta may not be as life-threatening." (THIJ, 2001)
Most nontraumatic subarachnoid hemorrhages are caused by intracranial saccular (berry) aneurysms. An aneurysm is a pathologic widening of the arterial lumen. The major types of intracranial aneurysms are (1) dissecting aneurysms, which are rare and usually…

Diagnosis Is a Process That Involves Determination
Diagnosis is a process that involves determination or identification o disease or illness. There are various factors which determine an individual's susceptibility to an illness. These can be categorized broadly as biological factors, socio-cultural factors, environmental factors, stressors, behavior, and personality. Since they lead to development of an illness they can consequently be used in the diagnosis of a particular illness. Biological factors There are various biological factors which can be used

[MSIT] the fact that X-rays are not used in MRI make it much safer for the patients as the radiation hazard is not there. Also, MRI provides greater contrast between the different tissues in comparison to a CT scanner offering more detailed anatomical review, better diagnostics, and improved interventional radiology. By adjusting the contrast mechanisms and other imaging parameters, the MRI allows the radiologist to obtain a highly detailed

However, one researcher, Dr. John Hall-Edwards of England, suffered such dramatic results that both
