<![CDATA[Premier Bintaro Hospital is equipped with High-end modalities with various types of advanced radiological examinations. There are several service centers that require continuous imaging support, such as vascular centers, Pain Centers, Spine centers and others. Integrated storage and access to patient data is needed to improve work efficiency. With the implementation of Picture Archiving And Communication System (PACS) in Radiology Unit, there are improvements in services and increased productivity when compared to previous system. This research will discuss a number of issues related to the role of PACS in Radiology services as evaluation material for services compared with the system before PACS is implemented. This research was made to determine the role of PACS in Premier Bintaro Hospital. This research is prepared with literature review, observation, and documentation. The application of PACS in Premier bintaro Hospital basically has the same workflow compared to workflows in general. Application of HL7 interface System which is equipped with DMWL makes PACS applied will integrated properly with HIS / RIS. The advantages of implementing PACS are more on data integration, storage, data editing, and presentation of data in digital form. The lack of PACS is more focused on the stability of the connection as the basis of the data transportation path needed. The challenge faced in the future is the problem of strengthening the stability of connection and education to users related. ]]>

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

<![CDATA[Background: Breast cancer is the most common case in Indonesia. One of the modalities for detecting breast cancer is MRI. The DWI sequence is one of the sequences used in MRI Breast. In breast DWI, the use of effective fat suppression techniques is essential. Several studies have stated that the most common fat suppression techniques used in breast MRI are STIR and SPAIR, because they are considered capable of optimally displaying lesion images. Signal intensity and image quality depend on fat suppression technique, the choice of method used for breast DWI should be considered, because it can affect lesion identification and ROI for calculating ADC used to differentiate benign and malignant lesions. Methods: This study is a literature review study with descriptive qualitative research type. Collect and analyze library sources from several published data. After being reduced based on the topic, 6 main relevant articles were found to be used as a basis to review, describing and discussing the results according to the topic and then criticizing according to the author's view and determining conclusions. Results: The results of this study showed that DWI-STIR and DWI-SPAIR on MRI Breast imaging have use in suppressing fat and can show the difference between benign and malignant lesions of the breast. With the difference in DWI-SPAIR, the results of SNR and CNR are higher, and DWI-STIR, the results are more homogeneous. Conclusion: DWI-STIR and DWI-SPAIR can suppress fat and differentiate lesions well. DWI-SPAIR is better for lesion visibility on high-tesla MRI, and DWI-STIR is better for low-tesla MRI.]]>
