It’s sensitive in detecting the present of hemorrhages that have susceptibility and blooming effect to hemorrhages. T2 fast field echo (T2 FFE) and susceptibility weighted imaging (SWI) are part of the gradient echo pulse sequences, in which T2 FFE sequences is conventional non- steady state imaging 2D milti-slice and SWI is 3D velocity compensated sequence gradient echo. On both the sequence is very good for asses the hemorrhages particularly microbleeds. This study aims to determine differences in image information and determine the most optimal image information between T2 FFE and SWI sequences in brain MRI axial slices with microbleeds cases. Methods : Type of research is quantitative experimental approach. The data was taken from October to November 2016 at Radiology Installation of Siloam Hospital Lippo Village. The study populations was all examinations brain MRI with the microbleeds cases, 5 samples with inclusion criteria described. Scanning by using T2 FFE and SWI sequences, then evaluation by respondents furthermore the data was processed using kappa test, and analyzing the date using wilcoxon test, and then to get an assesment of the most optimal images seen from the mean rank wilcoxon test. Results : The result was p-value 0,025 (p<0,05) means that Ho refused and Ha accepted, so that statistically showed significant differences at images information between T2 FFE and SWI sequences in examinations brain MRI axial slices with microbleeds case, with mean rank on SWI sequence is 3, and mean rank on T2 FFE is 0, so it’s can be concluded that SWI sequence produces a better images information on the examination brain MRI axial slices with microbleeds cases than T2 FFE sequence. Conclusion : there is a difference of images information between T2 FFE and SWI sequences in Brain MRI axial slices with microbleeds cases, and SWI sequences produces a better images information on the Brain MRI axial slices with microbleeds cases.

Background: Noise is a fluctuation in the value of CT number and Standard Deviation which is one parameter in the assessment of CT Scan image quality. This study aims to see the effect of changes in the angle of the gantry on noise and conformity with the BAPETEN standard of the value of the CT Number and Standard Deviation fluctuations produced. Methods: This type of research is quantitative with an experimental approach. The research subjects used water phantom to assess the value of CT Number and Standard Deviation by placing ROI on the resulting image. The SPSS test is used to see the relationship between changes in noise and noise. CT Number, Uniformity and Noise Uniformity tests are performed to assess CT Number and Standard Deviation in accordance with BAPETEN regulations. Results: An increase in noise is indicated by fluctuations in the value of CT Number and Standard Deviation resulting from the placement of the ROI at the center of each image produced by each change in the angle of the gantry. The average value of CT Number at the gantry angle 00 (-1.43), 50 (-1.48), 100 (-1.47), 150 (-1.58), 200 (-1.62), 250 (-1.68), 300 (-1.7). The average value of the Standard Deviation at the 00 gantry angle (2.36), 50 (2.35), 100 (2,3), 150 (2,33), 200 (2,42), 250 (2,57), 300 (2.62). There is a significant relationship to the Pearson correlation test between changes in gantry angle and CT Number and Standard Deviation values. CT Number, Uniformity, and Noise Uniformity Test results were used to assess the fluctuations of CT Number and Standard Deviation due to changes in the angle of the gantry in accordance with the standard BAPETEN No. 2 of 2018 on all changes in the 00 gantry angle to -300 with a range of 50. Conclution:. Noise fluctuations are caused by changes in the thickness of the scanning area object from changes in the gantry angle. The greater the change in angle of the gantry, the greater the thickness of the scanning area object. Changing the gantry angle causes the scanning area to change from the circle to the ellipse.
