QuestionDecember 16, 2025

Which technique provides detailed cross-sectional images of the brain and helps identify abnormalities like tumors or atrophy, but does not offer information about brain activity? Select one: a. Functional magnetic resonance imaging (fMRI) b. Magnetic resonance imaging (MRI) c. Computerized tomography (CT)scans d. Electroencephalog aphy (EEG)

Answer

b. Magnetic resonance imaging (MRI) Explanation 1. Identify key requirement We need a technique that shows **detailed cross-sectional brain images**, detects **structural abnormalities** (tumors, atrophy), but **does not measure brain activity**. 2. Evaluate options fMRI → shows activity via blood flow (wrong). MRI → detailed structural images, detects abnormalities, no activity data (correct). CT → also gives cross-sectional images, but less detail vs. MRI. EEG → records electrical activity, no structural imaging. 3. Select most accurate fit MRI meets the requirement best.
