Hemorrhagic Vascular Pathologies, II
Intracranial hemorrhage is a frequent indication for neuroimaging and accounts for about 10% of all strokes. Computed tomography (CT) remains the standard method of detecting intracranial hemorrhage, although radiologists need to also be familiar with the appearance of hematomas using magnetic resonance imaging (MRI). The first step is to confirm or exclude the presence of a hemorrhage, identify the anatomic compartment in which it is located, and approximate the age of the hemorrhage. The next step is to triage patients into those likely to have an underlying cause that requires urgent diagnosis and treatment and those who do not require urgent interventions. To do this, neuroimaging findings need to be considered in combination with patient age and medical history.
