What are the advantages and disadvantages of CT scanning?

Stroke is a health condition in which part of the brain receives insufficient oxygen supply due to an obstacle or blood loss. Some hundreds may have serious complications, while minor strokes may not cause any apparent symptoms. Strokes are diagnosed and evaluated by a combination of physical evaluation and clinical testing. A computer tomographic test (CT scan) is often used to determine the location and severity of the stroke. The use of CT scanning is useful because it can quickly provide doctors with an accurate picture of what occurs in the brain, but the procedure may be expensive and exposes patients to health risks of radiation and contrast dye. Since the areas of the brain affected by a stroke are deprived of blood, the cells begin to die from a lack of oxygen. Over time, more and more brain cells will be permanently damaged, eventually led long -term neurological problems. In some cases, patients are administered with a clot medication to break the blockade and restore normal flowto the blood. Other patients may require surgery to repair damage or alleviate swelling in the brain.

Diagnostic use CT scan for strokes has certain disadvantages. CT scan is generally not as sensitive as magnetic resonance imaging (MRI) and may have difficulty detecting smaller strokes. CT scan works on the same principles as X -ray imaging, so this procedure also exposes patients of radiation. This can be a special problem for children or patients who have already received a radiation exposure from other recent diagnostic testing. Dye used to ensure contrast in some CT scanning can cause an allergic reaction in some patients, although CT scanning is often performed without contrasting substances because the dye injection into the patient is required.

Overall, CT has been using stroke scanning, since 2011, providing doctors one of the fastest diagnosOut and patient assessment. Although the use of CT is associated with health risks, including radiation overdose, the ability of healthcare workers quickly determine the location and the extent of damage allows them to provide rapid treatment, which can help maintain brain tissue and neurological functioning. In cases where CT scan is insufficient, MRI or other imaging techniques can be used to provide doctors a better picture of what is happening in the patient's brain.
