A CT scan of the head or brain uses special X-ray equipment to create detailed images of your brain's structure. Before and after contrast means two scans are done. Initially, images are taken without a contrast dye. Then, a dye is given to highlight certain areas, providing a clearer picture.

A CT scan of the head or brain without contrast is a non-invasive imaging procedure. It uses X-rays to create detailed pictures of your brain, skull, and other structures inside your head. It helps to detect conditions like strokes, tumors, or injuries. No dye (contrast) is used in this test.
