Abstract :

CVT is not an uncommon condition with extremely varied clinical presentation and is the potentially treatable cause with low mortality and timely intervention bears better prognosis hence neuroimaging plays a pivotal role in diagnosis, management, and outcome.Its clinical presentation is varied and often dramatic. It often affects young to middle–aged patients, and more commonly women.Although recognized for more than 100 years, it has only in recent years come to be diagnosed frequently ante–mortem.This is partly due to greater awareness among physicians and neurologists, and partly due to improved imaging techniques. AIMS & OBJECTIVES: To compare the accuracy between conventional MR sequences (including TIME OF FLIGHT MR VENOGRAPHY) and contrast–enhanced MR VENOGRAPHY in diagnosing CVT, there by trying to avoid exposure of the patient to contrast and also save time in diagnosing CVT. So, as to start early treatment at an appropriate time. MATERIALS AND METHODS: • Place : Department Of Radiodiagnosis, Alluri Sita Ramaraju Academy of Medical Sciences (ASRAM), Eluru. • The Study Duration: 18 months (between October 2016 and March 2018). • Source Of Data: All patients with signs and symptoms of Headache, Pallor Convulsions, Altered sensorium, Focal neurological deficit like Hemiparesis, Paraparesis, Monoparesis, and Cranial nerve palsy referred to our Department, for MRI scan of the head ( MRV and Contrast MRV). • Study Population: 60 cases sent for MRI scan of BRAIN( MRV and Contrast MRV) with signs and symptoms. INCLUSION CRITERIA: Patients suspected to have cereal venous thrombosis. EXCLUSION CRITERIA: ▪ Patients with absolute contraindications for magnetic resonance imaging (MRI). ▪ Patients not willing for the study. Pre contrast images were taken followed by post contrast images after administration of 0.1 mmol/kg body weight of gadolinium intravenously. The standard imaging protocol was used.
