Computer Tomography (CT) scan of the head is an imaging procedure which uses X-rays to create detailed images of the head.
What is a CT Scan of the Head with Contrast2?
CT scan of the head with contrast uses a special contrast dye which helps highlight some areas of the head.
The CT scan is a non-invasive procedure, and hence is a popular imaging procedure for the head. The contrast dye in the CT aids the imaging of the head and highlights parts like blood vessels better. Generally, in a CT scan of the head using contrast, images are taken before and after injecting the dye to make better comparisons. The dye can be injected through an IV, or orally given in a CT scan.
CT scans of the head with contrast provide information on brain tumours, blood clots, and head injuries.
