CT Brain-Head without Contrast

About Test

CT (Computed Tomography) scan is an imaging modality that uses a series of X-rays taken from different angles and a computer to create cross-sectional images of internal body organs, bones, and soft tissues.

CT scan brain-head is performed to visualize brain tissue, its blood supply, and any disease processes causing symptoms like infection, hemorrhage, tumor, etc. CT scan brain-head can be performed with or without contrast. Contrast is a special dye usually injected through a vein in your arm to enhance the image quality. In some conditions and situations, there is no need to use contrast material, so no contrast material is used in CT scans without contrast.
