Seeing pain in 3D
UCSF Radiologist Dr. Dillon describes how CT scans are used as a 3D ultrasound to see back and neck pain in less than 20 seconds.
CT scanning involves X-rays in a tube. Tube is an x-ray source and detector of X-rays that circles the patient’s body quickly as the patient goes through. It creates a helix of data that can be done very quickly and reformat in different planes to form beautiful pictures. CT scan done can be done in 15-20 seconds and can see the arteries of the brain, which allows you to look for aneurysm, or a nerve that is abnormal.
