Comparison of quality of images performed with and without magnetisation transfer contrast in magnetic resonance imaging
Journal Title: Medpulse International Journal of Radiology - Year 2018, Vol 6, Issue 3
Abstract
Background: Magnetization transfer contrast (MTC) is most useful in improving image contrast and tissue characterization. It has also proven to be extremely useful in the reduction of background signal in MR angiography and improves the appreciation of tissue enhancement by intravenous contrast agents. Aim: To compare the quality of images performed with and without magnetisation transfer contrast in magnetic resonance imaging. Material and Methods: Magnetic Resonance Imaging of Central Nervous System was performed on a clinical 1.5 Tesla MRI system employing standardized protocol. Plain Brain and 3D Time of flight MR Angiography was performed without and with application of Magnetic Transfer preparation pulse. Results: Relative difference in tissue contrast was seen between images acquired without and with MTC. The magnitude of the tissue signals acquired with MTC showed significant improvement by a minimum of 1% to a maximum of 92% in this group of patients. The mean percentage of tissue signal magnitude was 41%. Conclusion: Magnetization Transfer Contrast 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.
