Prevalence of Anatomical Variants of Dural Sinuses by MRV Evaluation in Sohag

Prevalence of Anatomical Variants of Dural Sinuses by MRV Evaluation in Sohag

The purpose of this study is to use the MRV to depict the prevalence of anatomical variants of dural venous sinuses in Sohag population, which can help to avoid potenital pitfalls in the diagnosis of dural venous sinus thrombosis, venous infarcts and venous hemorrhage.

Inclusion Criteria:

• Sohag by nationality and residence, male or female by sex, having normal cerebral MRV reported and consented to participate in the research work will be included in this research.

Exclusion Criteria:

• Having the diagnosis of cerebral venous sinus thrombosis, congential or acquired intracranial abnormalities, ischemic or hemorrhagic stroke, intracranial hypertension, intracranial space occuping lesion, and previous head injury or neurosurgery, also patients with absolute or relative contraindications for imaging including claustrophobia, metallic implants, pacemaker and prosthetic heart valves for MRI.
