Does a CT scan always diagnose a stroke?
No. Even if you are having a stroke, it might not be seen on 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 (brainstem 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. 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 hairclips). 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 “donut hole” of the CT scanner. The
