RCVS (Reversible Cerebral Vasoconstriction Syndrome) - Cleveland Clinic
2023年8月28日 · People with RCVS may need to have both a CT and an MRI. A CT scan is faster and can help diagnose or rule out a stroke because it can spot blood vessel blockages inside your brain. That’s crucial because strokes are time-critical, and every minute counts. An MRI or MRA is often necessary once a healthcare provider rules out a stroke.
Reversible Cerebral Vasoconstriction Syndrome (RCVS)
2022年6月24日 · The ability to diagnose vasospasm noninvasively, by using either CT or MR angiography, has dramatically advanced the field. With a clearer concept of RCVS and improved diagnostic tools, it's likely that RCVS will be diagnosed more often in the future.

Reversible Cerebral Vasoconstriction Syndrome, Part 2: Diagnostic …
Noncontrast head CT should be the initial examination performed for patients presenting with symptoms suggestive of RCVS, particularly thunderclap headache. Noncontrast CT is an effective way to screen patients for the presence of intracranial hemorrhage, including subarachnoid and intraparenchymal hemorrhage, as well as ischemic stroke.
Reversible Cerebral Vasoconstriction Syndrome: An Important …
Reversible cerebral vasoconstriction syndrome (RCVS) is an increasingly recognized and important cause of acute headache. The majority of these patients develop potentially serious neurological complications. Rigorous investigation is required to exclude other significant differential diagnoses.
Reversible cerebral vasoconstriction syndrome: literature review
Reversible Cerebral Vasoconstriction Syndrome (RCVS) is a neurovascular condition characterized by a severe sudden-onset headache that may be associated with focal neurological deficits. On imaging, the suggestive finding corresponds to multifocal vasoconstriction of the cerebral arteries, with a spontaneous resolution of approximately 12 weeks.
Radiological Findings in Reversible Cerebral Vasoconstriction …
2024年5月3日 · Specific markers may facilitate the differentiation of RCVS from other conditions, thereby enhancing patient care. This review explores a wide range of radiological presentations, from vasoconstriction to infarctions and hemorrhages, thereby refining diagnostic criteria and guiding clinical practice.
