Role of Magnetic Resonance Angiography in Evaluation of Brain Pathologies

Background: MR angiography is the latest technique for theevaluation of cerebrovascular diseases. It is now usedcommonly for the evaluation of brain pathologies. Theadvantage is it is a non-invasive method of brain vasculature.The present study aimed to evaluate the role of MagneticResonance Angiography in the detection of brain pathologiesand to study the Role of Magnetic Resonance Angiography inCerebral Arteriovenous Malformations, Aneurysms, andCerebral infarctions.Methods: Data for the study was collected from patients withclinically suspected cerebral lesions or from patients, in whomprevious images depicted cerebral lesions, undergoing MRAfor evaluation of cerebral lesions Patients underwent MRimaging including TOF Magnetic resonance angiographyaccording to the set protocols after obtaining informedconsent. All these patients had undergone detailed clinicalevaluation by the referring neurosurgery unit.Results: In this study, a total of n=32 cases were included outof which n=6(18.75%) were AVM, n=10(31.25%) wereAneurysms, and n=16(50%) were cases of infarcts. Of the totaln=16 infarct cases n=8(50%) were found in the middle cerebralartery (MCA) n=4(25%) in ACOM and n=2 in PCOM, as well asInternal carotid artery (ICA). Of the MCA cases n=5(62.5%) wereright-sided and n=3(37.5%) were left-sided.Conclusion: MRA is now in routine use as a non-invasive toolfor imaging the cerebralvasculature. In cerebrovascular disease,it is the investigation of choice forpatients who are suspected/increased risk of having unruptured intracranial aneurysms,and intracranial vascular disease associated with acuteinfarction ,intracranial dissection of the carotid and/orvertebral arteries, and follow up cases of Cerebral AVMs.
