title: Magnetic resonance contrast enhancement in cerebral infarction.
abstract: Contrast enhancement may aid significantly in the diagnosis, dating, and grading of cerebral infarctions. On MR imaging, four patterns of contrast enhancement may be distinguished: intravascular, meningeal, transitional, and parenchymal. Each pattern has a different appearance, time course, and clinical significance. The anatomic and physiologic mechanisms that give rise to these distinct types of contrast enhancement in cerebral infarction are discussed.
