Which of the following brain-imaging techniques is considered the most effective?

A) Computerized tomography (CT)
B) Single photon emission computed tomography (SPECT)
C) Magnetic resonance imaging (MRI)
D) Positron-emission tomography (PET)

Magnetic Resonance Imaging

A non-invasive medical imaging technique used to visualize internal structures of the body in detail, using powerful magnetic fields and radio waves.

Computerized Tomography

An imaging technique that uses computer-processed combinations of many X-ray measurements taken from different angles to produce cross-sectional images of specific areas of a scanned object.

Brain-Imaging Techniques

Methods used in neuroscience and clinical diagnosis that visualize the structure or function of the brain, including MRI, CT scans, and PET scans.
