What are the risks of CT scans?

The test is painless and there are few side effects. The CAT scan uses very little x-ray radiation. If you receive contrast dye, there is a chance of an allergic reaction. This reaction can be serious, and may require treatment with appropriate medication. If you have allergies to any foods or medicines, particularly seafood or iodine, it is important to inform the technologist before the procedure. You should also tell the technologist if you could be pregnant. Digital Xray center, Ultrasound with 4D Center, CT Vascular Angiography Center

What happens during a CT scan?

        You will remove any metallic objects which could diminish the quality of the images (this includes jewelry, glasses, dentures, and hair clips). You may also be asked remove your clothing and put on a patient gown. A technologist will help you to lie face up on the scanner table, with your head toward the “doughnut hole” of the CT scanner. The technologist will position you on the table, and a device to hold your head in place may be used. Then he or she leaves the exam room and goes to the control room, where you can still communicate by intercom.

Does a CT scan always diagnose a stroke?

No. Even if you are having a stroke, it might not be seen on a CT scan for several reasons. In many cases, the involved area of the brain does not appear abnormal for the first several hours after the onset of stroke. Also, the stroke region may be too small to be seen on CT scan, or it may be in a part of the brain (brain stem or cerebellum) which the CT scan does not image well. Depending on the results of the CT scan, your doctor may wish to obtain additional testing, including an MRI scan. MRI can be more accurate for stroke and other conditions, but it takes longer and is often not available under emergency conditions.

Why do doctors use CT scans?

CT scans use computers and rotating X-ray machines to create images of slices, or cross-sections, of the brain. Unlike other techniques, CT scans (and MRI scans) can show the inside of the head, including soft tissue, bones, brains and blood vessels. CT scans can often show the size and locations of brain abnormalities caused by tumors, blood vessel defects, blood clots, and other problems. CT scans are a primary method of determining whether a stroke is ischemic or hemorrhagic.

CT Scan

Introduction:-
CT ScanThe CAT scan (also called CT scan) is well-known by name, but do you really know what it is and understand how it works? A CT scan is usually one of the first tests done in a stroke evaluation, particularly during an acute stroke in the emergency room. This test can show areas of abnormalities in the brain, and can help to determine if these areas are caused by insufficient blood flow (ischemic stroke), a ruptured blood vessel (hemorrhage), or a different kind of a problem. CT scans can be obtained on any part of the body, but the information here applies only to CT scans of the head.

For individuals experiencing memory problems, a comprehensive diagnostic evaluation is the first step toward determining the nature and significance of the problems, and getting the right care. Memory problems can result from many different medical conditions, including Alzheimer’s disease and Mild Cognitive Impairment, or they can be a result of normal aging. A diagnostic evaluation is the only way health care providers can assess a person's condition and provide an accurate diagnosis. The diagnosis then determines appropriate treatment and care options, as well as an accurate forecast of the course of the problem.

A diagnostic evaluation can also provide reassurance for aging individuals who are not currently experiencing symptoms, but are concerned about possible memory decline in the future. For these individuals, a diagnostic evaluation provides a basis for comparison with future assessments. CT Scan Center in Delhi, CT Scan Center in Chandigarh, CT Scan Center in Faridabad.
