Summary

An x-ray is a painless test that provides images of the interior of the body. These images are created by using low doses of electromagnetic radiation reflected on film paper or fluorescent screens. Chest, skull or spinal x-rays are often used to diagnosis certain neurological conditions, including Alzheimer’s disease, dementia, epilepsy and head injuries.

X-rays work by passing small amounts of electromagnetic radiation through the body to produce images of bones, teeth and internal organs. The type of x-ray administered depends on which part of the body needs to be examined.

In some cases, standard x-rays are not enough for diagnosing a patient’s neurological condition. In these instances, there are a number of specialized x-rays available, including: CAT scan (computed axial tomography), fluoroscopy and angiography.

In general, no special preparation is needed before an x-ray is taken. However, sometimes a special dye called a contrast medium is used, in which case a physician may advise the patient how to prepare for the x-ray. Depending on the procedure, the patient will sit, stand or lie down between the x-ray machine and x-ray film.

X-rays usually do not cause any side effects when administered correctly. The levels of radiation used in x-ray procedures are so low that they pose only minimal risk to patients.  However, x-rays may be harmful to developing fetuses. Therefore, women who are or may be pregnant should inform their physician or x-ray technologist of their condition.
