SWI is therefore highly effective in visualizing small cerebral blood vessels.rnIn relation to which, the choice of slice gap can influence the anatomical information of blood vessels obtainedrnduring brain MRI examinations.rnResearch Objective: This research aims to analyse the effect of slice gap variations of 0 mm, 0.5 mm, and 1rnmm on the anatomical image information of blood vessels in brain MRI examinations using the SWIrnsequence.rnResearch Design: This research applied a quantitative method with an experimental approach. The BrainrnMRI examinations were performed using three slice gap variations of 0 mm, 0.5 mm, and 1 mm, while allrnother acquisition parameters were firmly kept constant. As for the research, it included five patient samples.rnThe quality of vascular visualization was assessed subjectively by two respondents using structuredrnquestionnaires. Thereafter, statistical analysis of the data was then performed using the Friedman test,rnfollowed by post-hoc Wilcoxon tests.rnResearch Results: As the results, this research demonstrated that there are significant differences inrnanatomical image information on SWI sequences with slice gap variations of 0 mm, 0.5 mm, and 1 mm.rnAmong these, a slice gap of 0 mm provided the best vascular visualization, showing superior anatomicalrncontinuity and clearer vessel detail compared to the other variations.rnKeywords : Magnetic Resonance Imaging, Susceptibility Weighted Imaging, Slice Gap, BloodrnVessels, Brain, Image Information
