Abstract

Three sagittal plane sequences, T2 * MERGE, T2 FSE, and PD FSE Fat Saturation were used for MRI examination of knee joints in the Radiology Installation of Panti Rapih Hospital but there was no clarity yet in the use of the sequences in the case of osteoarthritis. The aim of this study was to find out the results of the sagittal image of knee joint MRI between T2* MERGE, T2 FSE, and PD FSE Fat Saturation sequence with osteoarthritis (OA). Those sequences were compared with two methods to assess image quality and anatomical information. This research type is quasi experiment. Ten patients underwent knee joint MRI examination with 1.5T GE MRI at Yogyakarta Panti Rapih Hospital. Assessment of anatomical information was analyzed using visual grading characteristics (VGC). Interobserver reliability was calculated using intraclass correlation coefficient (ICC). The image quality of all three sequences was compared using the Friedman test.Results showed that there is a difference in overall SNR value between the sagittal image of T2* MERGE, T2 FSE, and FSE Fat Saturation sequences (P
