Computed Tomographic Scan

Computed-tomography scan (CT) is a series of x-ray images taken from different angles, which are combined by a computer, into a representation of a slice through the body. CT scan images provide more detailed information than X-rays do. A CT scan has many uses, but is primarily used to quickly examine people who may have internal injuries from car accidents or other types of trauma. A CT scan can also be used to visualize many parts of the body and is used to diagnose disease or injury as well as to plan medical, surgical or radiation treatment. A brain CT is used to evaluate various structures of the brain to look for a mass, stroke, area of bleeding, or blood vessel abnormality. It is also sometimes used to look at the skull. CT scans have
improved patient comfort because a scan can be performed quickly. Improvements have led to higher-resolution images, which assist the doctor in making a diagnosis. CT scans can also help doctors reveal small tumors, which they cannot see with a X-ray. CT scans are also used to check on the success of a surgery.
