A radiological technique used to identify the loss of neurons in specific areas of the brain is known as:
A) PET scanning
B) Functional MRI
C) Volumetric neuroimaging
D) Transcranial Doppler ultrasonography

Question

Quizplus · Accepted Answer

Volumetric neuroimaging can identify localized areas of brain atrophy (e.g., the loss of neurons from the frontal lobes of the brain in frontotemporal dementia, or from the hippocampus in people with schizophrenia). PET scanning is used for many other imaging applications in which glucose metabolism increases or decreases. For example, it is used to identify metastases from cancers (which have increased glucose metabolism relative to normal cells). Functional MRI is a technique used to identify other metabolic processes in brain cells (e.g., which parts of the brain activate during particular activities or thought processes). Transcranial Doppler ultrasonography is used primarily to identify blood flow (or obstructions to blood flow) through arteries inside the skull.
