Low doses of radioactive substances are used in the brain-imaging technique of __________.A)  EEGB)  CT scanC)  PET scanD)  MRI

Jakira Tucker · Accepted Answer

Final Answer : C, Explanation :  PET scan (Positron Emission Tomography) uses low doses of radioactive substances (radiotracers) to produce images of the brain. The radiotracer is injected into the patient's bloodstream and travels to the brain, where it emits radiation that can be detected by the PET scanner. This allows researchers to observe brain function in real time. EEG (Electroencephalogram) measures electrical activity in the brain and does not involve the use of radioactive substances. CT scan (Computed Tomography) and MRI (Magnetic Resonance Imaging) use X-rays and magnetic fields, respectively, to produce images of the brain, but do not involve the use of radioactive substances unless contrast dye is used.

A) EEG
