However, abdominal MRI examinations are frequently affected by pulsation artifacts caused by pulsatile blood flow in the abdominal aorta. Consequently, these artifacts result in ghosting on the images, which degrades image quality and complicates diagnostic interpretation. For this reason, one approach to reducing this interference is the application of saturation bands, which function to suppress the signals from the areas outside the Field of View (FOV), in order to minimize the motion-related effects.rnResearch Objective: this research aims to analyse the effect of saturation band application on the occurrence of abdominal aortic pulsation artifacts in axial T1 dual-echo abdominal MRI examinations undertaken at Pertamina Central Hospital (RSPP), South Jakarta.rnThe research was conducted at Radiology Department of Pertamina Central Hospital starting from July up to October 2025 and involved seven patients using primary data. Two imaging conditions were accordingly applied namely variation in the placement of saturation bands in the superior inferior direction and imaging without the use of saturation bands. Image evaluation was performed using a questionnaire assessed by three respondents, consisting of two radiographers and one MRI-specialized physician. Furthermore, after the data were substantially collected, statistical analysis was carried out using SPSS software. If the data were normally distributed, a paired-sample t-test was applied; if the data were not normally distributed, the Wilcoxon signed-rank test was used.rnThe results of this research demonstrate a significant difference between the use of saturation bands and imaging performed without saturation bands. The application of saturation bands was provenly shown to minimize the occurrence of artifacts; therefore, it significantly improves the image assessability and diagnostic evaluation.rnrnKeywords : Abdominal MRI, Saturation Band, Pulsation Artifact, Abdominal Aorta, T1 Dual EchornReferences : 32 (2015–2025)rnrnTranslated by:rnrnrnrnrnrnSuhendar, S.S., M.Pd. rnEnglish Lecturer
