Question

a(n) ____ scan uses radioactive markers in the blood to monitor blood flow and metabolic activity via x - ray. a. pet b. ct c. tms d. eeg please select the best answer from the choices provided

Explanation:

PET (Positron - Emission Tomography) scan uses radioactive tracers in the blood to monitor blood flow and metabolic activity via x - ray. CT (Computed Tomography) uses x - rays to create cross - sectional images of the body but not radioactive markers for monitoring metabolic activity in this way. TMS (Transcranial Magnetic Stimulation) is a non - invasive brain stimulation technique and EEG (Electroencephalogram) measures electrical activity of the brain.

Answer:

A. PET
