Ansalisis Kualitas Citra Brain Variasiflipangle(FA) dengan Menggunakan Squens Spin Echo Pada Magnetic Resonance Imaging (MRI)

Abstract

This Research done at image three people of patient by using MRI 1,5T inspection of MRI Brain, to analyse influence of FA to quality of image of MRI brain of wight of T2 spin echo. items of Research result of image of MRI obtained from variation of flip agle, wight of T2 spin echo to quality of image Brain, what is done in each patient. the Research in RS Field Firmness. Procedures of Research with preparation of Magnetic implement of Resonance Imaging, patient preparation, arrangement from Flip Angel. Result of statistical test of this research is obtained by that FA 1200 ,1400 and 1600 having an effect on signifikan to quality draw, with value of TR of 5000 of ms and TE of 96 ms of its meaning is of FA to quality draw contrast of image of Brain cutting of axial with analysing result of Middle measurement, Under right, Under Left, For Right and For Left getting that middle area more signifikan because more amount is aqueous. Than 8 image assessed to own quality of more optimal image at flip angle ( FA) 1600 . From result obtained inferential that progressively go up value of Flip Angle ( FA) hence will progressively improve Signal Noise to Ratio (SNR).
