Abstract
Neuroimaging is integral in the diagnostic algorithm and follow-up of patients with hemorrhagic stroke. The role of the neuroimager is to recognize and localize the hemorrhage and attempt to determine its etiology. Non-contrast computed tomography has long been the initial imaging tool in the acute neurologic patient. As MRI technology and angiographic imaging has evolved, they too have proven to be beneficial in narrowing the differential diagnosis and triaging patient care. Several biological and physical characteristics contribute significantly to the appearance of blood products on neuroimaging. To adequately interpret images in the patient with hemorrhagic stroke, the evaluator must have a knowledge of the interplay between imaging modalities and intracranial blood products. Additionally, an understanding of technical parameters as well as the limitations of imaging modalities can be helpful in avoiding pitfalls. Recognition of typical imaging patterns and clinical presentations can further aid the evaluator in rapid diagnosis and directed care.
