ANALISA PERBEDAAN INFORMASI ANATOMI ANTARA SEKUENS T2 TURBO INVERS RECOVERY MAGNITUDE DENGAN SEKUENS T2 TSE FAT SATURATION IRISAN SAGITAL PADA PEMERIKSAAN MRI LUMBAL KASUS HERNIA NUCLEUS PULPOSUS

MRI Lumbal is a more frequent examination used to evaluate degenerative changes, one of which is the nucelus pulposus hernia. The nucelus pulposus hernia is the discharge of the nucleus pulposus of the intervertebral disc because of the tearing of the annulus fibrosus connective tissue. The sequence used is to use T2 Turbo Invers Recovery Magnitude sequence and T2 TSE Fat Saturation sequence which is a fat-pressing technique that aims to reveal the network contrast of an anatomy well from the surrounding fat signal. This study aims to determine the difference of anatomical information and to find an optimal description of anatomical information between T2 Turbo Invers Recovery Magnitude sequences and T2 TSE Fat Saturation sequences of sagittal slices on Lumbal MRI examination of the hernia nucelus pulposus case.This type of research is qualitative research with experimental approach. This research was conducted at Haji General Hospital Surabaya. Data were 10 Lumbal MRI images of nucelus pulposus hernia case with T2 Turbo Invers Recovery Magnitude sequence and T2 TSE Fat Saturation sequences of sagittal slices. Image assessment is done by 3 respondents about the resulting image information. Data analysis was performed by cohen's kappa test to determine the level of agreement of the three respondents, the wilcoxon test to see the difference of anatomical information, and using the mean rank method to see the optimal sequence.The results showed that between T2 Turbo Invers Recovery Magnitude sequence with T2 TSE Fat Saturation sequence with significance value p value 0,004 which means there is difference of anatomical information. Sequence T2 TSE Fat Saturation is more optimal in displaying anatomy with a mean value of 5.50
