Brain Aneurysm: test yourself

Most aneurysms localized in the brain, remain unnoticed until burst or they will not be discovered by chance during a particular survey with the help of visualization authority. Such statistics. And many people live, not knowing what danger expose themselves daily. Meanwhile, there are several methods effective correction of aneurysms. For example, it is possible to "turn off" of blood flow through clipping or endovascular occlusion before as happen gap. And in this case, time is especially important to notice the problem.

Today practiced several tests to diagnose a brain aneurysm in the early stages and determine the optimal treatment strategy for them.

1. CT, or computed tomography, X-ray is the basic method. With this method for creating two-dimensional images ( "slices" of the brain, skull) using X-rays.

Often, before the procedure to better assess the state of the arteries and efficient search of the aneurysm in the patient's blood stream is introduced a special contrast agent. This method of research is already called CTA (CT angiography), and it provides more detailed and clear images of blood flow in cerebral arteries. It is this method is able to show the exact location, size and shape of the aneurysm as unexploded, and already torn.

2. MRI, or magnetic resonance imaging, which uses a magnetic field to create two- and three-dimensional images of the brain in detail. With this method, you can easily determine whether there is bleeding in the brain of the patient. It also shows the size, shape and location of the aneurysm (with the introduction of contrast medium).

3. Cerebral angiography - imaging technique with which experts can detect occlusion (occlusion) cerebral arteries or neck. The same method helps to identify existing aneurysm and arteriovenous malformations. This test is used when it is necessary to determine the cause of cerebral haemorrhage, the position, size and shape of the aneurysm in detail. A contrast agent is administered at the cerebral angiography, it makes it possible to accurately describe the full picture of any occlusion of the arteries.

4. Analysis of the cerebrospinal fluid that allows to detect subarachnoid brain hemorrhage and intraventricular. But only to find out. The reason for the hemorrhage already determined via other (described above) tests.
