ReviewThe magnetic resonance imaging of infections and inflammatory diseases.
The MR features of inflammatory lesions of the central nervous system are reviewed in this article, and the sensitivity and specificity of MR and CT in the detection of these lesions are compared. The advent of CT dramatically improved the morbidity and mortality of inflammatory disease by facilitating earlier and more accurate diagnosis which, in turn, produced more timely medical and surgical intervention. The efficacy of MR in the evaluation of inflammatory lesions must, therefore, be compared to CT in order to accurately asses its role.

Case ReportsArtifacts and diagnostic pitfalls on magnetic resonance imaging: a clinical review.
High field MRI of the brain occasionally exhibits imaging artifacts; most artifacts are obvious and easily recognized, but some are subtle and mimic disease. A thorough understanding of brain MRI artifacts is important to avoid potential diagnostic pitfalls. ⋯ These include additional projections, different pulse sequence, and 90 degree shift of phase-encoding gradient. The use of respiratory gating or cardiac gating may also improve image quality by reducing some of the motion-related artifacts.
