OPTIMALISASI CITRA MRI WRIST JOINT DENGAN PENERAPAN 3D ISOTROPIK PADA PEMBOBOTAN PROTON DENSITY DI INSTALASI RADIOLOGI RSUP DR. M. DJAMIL PADANG

MRI is a medical imaging modality that works by utilizing hydrogen atoms in the body. Imaging does not use ionizing radiation but uses an external magnetic field. able to provide good soft tissue contrast based on nature of tissue. The wrist joint complex consisting several bones and joints. consist including distal radius ulna, 8 carpal bones, proximal part consists 5 metacarpal bones. This type research quantitative study with experimental approach. will be conducted comparing isotropic 3D sequences PDW TSE SPAIR Cor sequences. Data collection was carried out from May July 2022 at Radiology Installation RSUP DR. M. Djamil Padang. author took Wrist Joint examination data as many 10 volunteer samples. Based results conducted, researchers concluded Wilcoxon test for each anatomy were used see differences clarity anatomical information produced Isotropic sequence Coronal sequence. So test, most optimal producing higher than which criteria Ligament, Cartilage, TFCC, Bone, except cartilage has lower value
