Question

Quizplus · Accepted Answer

Magnetic resonance imaging (MRI) is considered the most effective brain-imaging technique because it provides high-resolution images with excellent soft tissue contrast without exposing the patient to ionizing radiation. PET and SPECT provide functional information but have lower spatial resolution and are less commonly used. CT involves radiation exposure and provides less detailed images than MRI.
