E) computerized tomography

Question

Quizplus · Accepted Answer

Magnetic resonance imaging (MRI) utilizes magnetic fields and radio waves to create detailed images of internal structures in the body, including the brain. With specialized MRI techniques, such as diffusion tensor imaging (DTI), it is possible to visualize the structural differences between white matter and gray matter in a living subject. Confocal laser scanning microscopy, transneuronal tracing procedures, and stereotaxic procedures are invasive techniques often used in animal models and not feasible or ethical for use in living human subjects. Computerized tomography (CT) is effective in visualizing brain structure but has limited sensitivity in differentiating gray and white matter.
