Significance of magnetic transfer contrast in MR imaging of central nervous systems
Journal Title: Medpulse International Journal of Radiology - Year 2018, Vol 6, Issue 2
Abstract
Background: Magnetic Transfer Contrastis a useful diagnostic tool in characterization of a variety of central nervous system (CNS) infections. The role of MTC has been studied in the detection and diagnosis of meningitis, encephalitis, CNS tuberculosis, neurocysticercosis, brain abscess and multiple sclerosis. Aim: To assess the significance of magnetic transfer contrast in MR imaging of central nervous system. Material and Methods: Magnetic Resonance Imaging of CNS was performed on a clinical 1.5 Tesla MRI system employing standardized protocol on 38 patients. Plain Brain and 3D Time of flight MR Angiography was performed without and with application of Magnetic Transfer preparation pulse. Results:10 out of 38 patients underwent plain magnetic resonance imaging. The Magnetic Resonance Angiogram of all the eight patients revealed no significant abnormalities except for one patient showed hypoplastic right vertebral artery. By employing magnetic transfer contrast pulses, signal intensity of white and grey matter was reduced. The signal intensity of Brain parenchyma was suppressed leaving signal from blood unaffected, thus improving small vessel visibility. Conclusion: MTC plays a pivotal role in magnetic resonance imaging of Central nervous system by improving image contrast and tissue characterization, and therefore, should form a part of the routine diagnostic imaging protocol.
