MRI Artifact Analysis and Correction Techniques
Sameer Ahmad Ganaie, Vanshika, Mubashir Habib
Abstract: Background: This research plays a strong role on explaining the different number of artifacts occurrence due to software, hardware, human physiological functions with the aim of promoting artifact detection and corrective remedies needed to optimize and increases the image quality in Magnetic Resonance Imaging. Especially it is to understand origin of artifacts and mimic the pathology as they can lead to misdiagnosis. Objective: The primary objective of this article is to unlock the goals with these proven objective-setting strategies that MRI artifacts and highlights clues which suggest the rectification. Methodology: This was a prospective study which included all the patients that were referred to our centre for various MRI examinations. The study was carried at 1.5 Tesla Symphony MRI, March Imaging & Diagnostic Center, Bikaner India. All MRI examinations were conducted under the supervision of an experienced radiologist and performed by trained technologists. During the imaging process, the acquired MR images were carefully assessed for the presence of artifacts. The focus was on identifying the specific MR parameters at which these artifacts occurred. Following the identification of artifacts, appropriate remedial measures were promptly implemented to address and mitigate their impact on the image quality. Result: A total of 169 patients comprising 88 females and 81 males, referred to our department for MRI examinations of various body parts were studied. The commonest artefact observed was motion artefact in 120 (55.56%) patients followed by susceptibility artefact, Gibb?s artefact, and aliasing artefact. Less common artefacts observed were chemical shift artefact, shading artifact, high impulse noise, and zipper artefact. Conclusion: MRI can be significant challenge in diagnostic imaging. However, with knowledge and appropriate measures, they can minimize and overcome. As a radiographer we must continue to learn and adapt the parameters and conditions of medical imaging to provide best possible outcome.
