Study of MRI Image Artifacts in Khartoum State Centers

Abstract

The aim of this study was to evaluate the common Artifacts in MR images in Khartoum State centers and detecting their Causes in order to give a solution for each if possible. Using observation to calculate the data along 3 month on Khartoum specialist hospitals , Artifacts in magnetic resonance images, as in different Radiologic imaging Modalities are common and lead to misdiagnosis or at least decrease the Image quality. The causes are different and as a result there are many Types of Artifacts and The result showed that the most common Artifact is Motion record High percentage 63%, the second common Artifacts was Phase mismmaping 30%, then Truncation 7%. Through my search for most common Artifacts in the magnetic resonance imaging centers in Khartoum state we found most common artifacts that is of patient movement (motion Artifacts) due to differentials reasons e.g.: unconscious patient ,lack cooperation .And Phase mismmaping Artifacts appear from involuntary motion e.g.: chest moving during respiration, also Truncation Artifacts caused by different signals high and low signals duplication transition signals, common sites appear that’s artifacts in cervical spine T1 sagittal . But there are some Artifacts such as lower rates e.g.: Cross Excitation Artifacts appears in spine (Lumbar) due to not Ensuring that there is at least a 30% gap between slices. There is a previous study in Sudan; I spoke on the subject but at different rates.
