Abstract


Magnetic resonance imaging (MRI) is very useful in the medical sector as it uses radio waves and robust magnetic fields to produce images of the inside of the human body. MRIs are so helpful in pathologies. However, artifacts in MRI occur due to the complex nature of MRI. Artifacts in MRI may reduce the examination quality and may also be confused with pathology. Failing to identify artifacts in MRI can bring troubles. Hence, it’s very important to reduce or avoid artifacts in MRI. The major reasons behind artifacts in MRI are improper action of the MRI scanner, magnetic susceptibility, motion, chemical shifts, variation in signal intensity, etc. Due to MRI artifacts, patients can suffer from serious problems. Therefore, we have analyzed the physicochemical natures of artifacts in MRI. The research has made attempts to identify various types of artifacts in MRI and find out the causes of these artifacts. There have been samples of various types of artifacts based on which the analyses have been done. Based on these identifications of artifacts, there have also been discussions and analyses on how to avoid artifacts in MRI.
