D) Encephalography
E) Pneumoencephalography

Question

Quizplus · Accepted Answer

Positron emission tomography (PET) is a functional imaging technique that uses radioactive tracers to identify abnormal tissue metabolism. It can detect changes in glucose metabolism, which can indicate the presence of cancer or other diseases. Stereotaxy and computerized tomography are structural imaging techniques that provide detailed images of the brain, but they do not directly measure metabolic activity. Encephalography and pneumoencephalography are invasive techniques that involve the injection of a contrast agent into the brain, and are rarely used today.
