Correlation between MRI and MRA in Cases of Cerebral Ischemic Stroke.

Dr. R. Sudheer, Dr. Sriramaneni Venkateswara Rao

Abstract :

MRI is superior to CT when therapeutic interventions are considered1. MR imaging in stroke is targeted towards assessment of– Parenchyma , extra cranial and intracranial circulation , assess CBV, CBF and MTT, and Penuma . Diffusion–weighted MR imaging is more sensitive for detection of hyper acute ischemia. Diffusion–perfusion mismatch indicates penuma. Gradient echo MR sequences aid in detecting hemorrhages. MR angiography enables to assess the status of the neck and intracranial vessels. MR angiography is a Clinically important non–invasive method for the evaluation of vascular structures of neck and intracranial vessels. AIMS & OBJECTIVES: Role of MRI in the detection of cereal ischemic stroke. To analyze the socio–demographic profile and risk factors in patients with cereal ischemic stroke. To determine the location and the territory of the involved blood vessels. Role of non–contrast MR angiography in the detection of salvageable tissue (penuma) The incidence of negative cases (stroke mimics). SELECTION OF PATIENTS:Study design: Observational Cross–Sectional Study. Study duration: Study was carried over a period of 2 years from Feuary 2015 to Feuary 2017. Sample size: A total of 300 patients referred to the Department of Radio–Diagnosis ,ASRAM MEDICAL COLLEGE , with clinical suspicion of cereal ischemic stroke are included in the study based on the inclusion criteria. All MRI scans were performed on a 1.5T Seimens Magnetom. INCLUSION CRITERIA:•All patients clinically suspected of cereal ischemic stroke •Cases of all age groups irrespective of sex. EXCLUSION CRITERIA: •Patients with history of the metallic implant, foreign body, pacemaker, aneurysm clip, recently implanted prosthetic valve. •Patients too unstable to undergo MRI scan who are on ventilator support. •Patients with history of claustrophobia.
