Your doctor might recommend a CT Scan to provide detailed views of many types of tissue, including the lungs, bones, soft tissues and blood vessels. If you suffered a stroke, a CT Scan can determine the location of the blockage or bleeding in the brain that has caused the stroke. It also allows your doctor to identity both normal and abnormal structures in a painless, non-invasive and accurate manner.
A CT Scan aids in planning and preparation of particular surgeries including awake craniotomy (brain surgery to remove brain lesions) and deep brain stimulation surgery. It is also useful in the planning and guiding of radiotherapy (cancer treatment), needle biopsies and other minimally invasive operations.
