MRI shows which of the following?

• A. Brain activity
• B. Brain waves
• C. Brain structure
• D. Neural connections

Answer: (C)

MRI primarily images brain structure. The technique uses strong magnetic fields and radiofrequency pulses to align hydrogen protons and then reconstruct detailed cross-sectional images of soft tissues, revealing the brain’s anatomy—gray matter, white matter, ventricles, and potential structural abnormalities like tumors or lesions. This is why MRI is the go-to tool for assessing anatomy. Brain activity isn’t shown by a standard MRI; that information comes from functional MRI, which measures blood flow changes related to neural activity but under a different protocol. Brain waves are electrical patterns detected by EEG or MEG, not MRI. Neural connections can be inferred with diffusion MRI techniques to map white matter tracts, but a typical MRI image focuses on structure rather than direct connectivity. So the best answer is brain structure.
