MR imaging of the brain.

MR imaging of the brain. Michael of the Art MD Brant-Zawadzki, MR Imaging of the Brain’ imaging with magnetic resonance (MR) has rapidly reached clinical maturity.

Abstract

Michael of the Art MD Brant-Zawadzki, MR Imaging of the Brain’ imaging with magnetic resonance (MR) has rapidly reached clinical maturity. The greater sensitivity of MR imaging to pathologic alteration of cerebral tissues assures its replacement of computed tomography (CT) as the first-line diagnostic imaging study for most patients with neurologic manifestations. The incipient introduction of paramagnetic contrast agents for intravenous use will further expand the utility of MR imaging and will limit the need for CT scanning of the brain. Only those patients with implanted or attached metal devices that are incompatible with strong magnetic fields will still require CT study. For the remainder of patients, CT will be relegated to a complementary status. This overview briefly summarizes the current state of the use of MR imaging in the study of the brain. I will touch on the basis for MR capabilities, mention established and controversial technical points, and summarize clinical applications as well as limitations of use. RAIN and the controlled perturbation of these nuclei within the fields by radio-frequency (RF) waves form the basis of MR imaging. The physical underpinnings of these principles cannot be reiterated here; the interested reader is referred to other sources
