Computed transaxial tomography (CT or CAT scan) is a non-invasive procedure. The other options involve inserting instruments or substances into the body, making them invasive procedures. The Wada technique involves injecting anesthetic into the carotid artery to determine language function, an air encephalogram involves injection of air into the brain, and angiography involves injecting contrast dye into blood vessels to visualize them.
