ANALISIS PERBEDAAN KUALITAS DAN INFORMASI CITRA ANTARA T2WI FAST RECOVERY FAST SPIN ECHO DAN T2WI PROPELLER PADA PEMERIKSAAN MRI BRAIN POTONGAN AXIAL

Background: MRI Brain is needed by patients who are calm during the examination. MRI with a long time can cause the process of repeatedly taking pictures due to the movement of the patient. One of the protocol recommendations on brain MRI examination using Fast recovery fast spin echo (FRFSE) aims to obtain a pathological picture, also enhances the healthy, effective tissue increase the weighting level of T2 and increase SNR by speeding up the scanning time. While for PROPELLER is used to minimize the occurrence of motion artifacts and get the desired picture. The purpose of this study was to determine the differences in image quality and information and to know better between using T2WI FRFSE and T2WI PROPELLER on an axial MRI brain examination.Methods: This type of research is quantitative research with an experimental approach. The study was conducted at the Yogyakarta Panti Rapih Hospital using a sample of 10 patients and 3 radiologists as respondents. Data analysis was performed by the Wilcoxon test to determine the quality and information of anatomical images better than the two sequences seen from the mean rank value, while to find out information on artifact images using the Mc Nemar test.Result: Statistical results prove that there is a difference between the use of T2WI FRFSE and T2WI PROPELLER sequences on SNR image quality (p = 0.005) and CNR (p = 0.013) with (
