MRI can distinguish various structures in the brain (e.g. white matter from gray matter)by doing which of the following?
A)Staining the cells differently
B)Implanting electrodes at different depths
C)Directing ionizing radiation at the brain from different angles
D)Varying the frequency of the radio pulse
E)Observing infrared reflectance

Question

Quizplus · Accepted Answer

MRI uses a strong magnetic field and radio waves to generate images of the brain. By varying the frequency of the radio pulse, different structures in the brain can be distinguished based on their different magnetic properties. Staining, electrodes, ionizing radiation, and infrared reflectance are not used in MRI.
