Stroke in the tropics.

Similar to northern developed countries, cerebrovascular disease is a leading cause of morbidity and mortality in tropical countries. The epidemiology of stroke in the tropics is different from one tropical region to another and from the tropics to northern latitudes. In tropical regions, stroke is due to the conventional mechanisms encountered in other latitudes, as well as unusual causative mechanisms unique to the tropics. In tropical regions, infectious causes of stroke and nonatherosclerotic mechanisms are more common than in nontropical areas. Our current knowledge of stroke in the tropics is limited by the financial restrictions existing in such regions limiting health care delivery and epidemiological research.

Magnetic resonance imaging in the evaluation of intracranial hemorrhage.

Magnetic resonance imaging is emerging as a valuable tool for the urgent evaluation of patients with acute stroke. This review focuses on the applications of magnetic resonance imaging in the diagnosis and management of intracranial hemorrhage. The biophysical properties of blood in the neuroaxis and the magnetic resonance imaging evolution of intracranial bleeding are reviewed. The potential applications of magnetic resonance imaging in the evaluation and therapy of specific types of intracranial hemorrhage are discussed. Emphasis is made on the superiority of magnetic resonance imaging in detecting intracranial hemorrhage and ischemic stroke. Although there is some hesitation to perform magnetic resonance imaging to evaluate acute intracranial hemorrhage, there is strong evidence that magnetic resonance imaging is not inferior to computerized tomography in this clinical setting. In the era of acute stroke intervention, magnetic resonance imaging offers significant advantages over computed tomography.
