Diferenciar entre los Tipos de Accidentes CerebrovascularesAccidente cerebrovascular isquémico y hemorrágico

The differentiation of ischemic and hemorrhagic stroke at the earliest possible stage is crucial for all following therapeutic decisions. Although certain symptoms, such as vomiting, systolic blood pressure over 220 mmHg, severe headache, reduced consciousness, coma, and progression within hours or minutes, may suggest a diagnosis of stroke, none of these signs are specific.
Therefore, international guidelines consider neuro-imaging are mandatory to prove or rule out intracranial hemorrhage. Siemens supports you with dedicated, fast, and reliable CT and MR imaging protocols in this critical early phase of stroke diagnostics.


CT is considered the gold standard¹ for identifying and locating acute intracranial hemorrhage. It should be performed as soon as possible after symptom onset.
CT is highly sensitive in detecting acute bleeding. Combining initial and follow-up CT enables the detection of hematoma expansion and provides predictive evidence for clinical deterioration and mortality.
Siemens supports you with latest CT scanning technology and imaging workflows to provide your patients with fast and reliable diagnostics in stroke emergencies.


MR imaging (MRI) is equally suitable and sensitive as CT for identifying acute hemorrhage, but requires special sequences, such as gradient-recalled echo (GRE) or T2* susceptibility-weighted imaging to reliably detect acute bleeding.
MRI provides excellent anatomical information about brain tissue, including the posterior fossa, which can be difficult to investigate in CT imaging.
