Studi Perbandingan Artefak Antara MRI Lumbal T1 Spin Echo Dengan Pre Saturasi Dan T1 Spin Echo Tanpa Pre Saturasi

Abstract

This study is an experimental study, data collected by observation. Data processed by the Friedman test and Wilcoxon test. From the results of this research note there is a difference between Spin Echo T1 artifact lumbar MRI with pre saturation and Spin Echo T1 without pre-saturation. These results can be seen from the average value of the overall test Friedman test with p value < 0.001 in axial cuts and sagittal cuts. Then the ratio of artifacts to see the value of the Wilcoxon test performed two variables, to determine the differences of each placement pre saturation. Values ??obtained in the setting of artifacts terkecul Anterior presaturasi in both sagittal and axial to pieces.
