Background: The current fat suppression technique in magnetic resonance imaging (MRI) significantly diagnoses abnormalities in musculoskeletal disorders. The spectral attenuated inversion recovery (SPAIR) fat suppression (FS) technique had an inversion delay (ID) parameter that allows choosing between full or partial FS. This was the first research related to the optimal setting of the ID time variation in the SPAIR technique on T2-weighted MRI wrist joint images.Objectives: This study aims to find out anatomical information with the most optimal ID value of the MRI wrist joint image T2 turbo spin-echo (TSE) FS SPAIR coronal slice sequence.Method: This study was a pre-experimental post-test only. Scanning MR wrist joint 16 volunteers took data with the qualitative analysis used three radiologists (visual grading) with statistical data analysis.Results: Image information of the MRI wrist joint T2 TSE FS SPAIR coronal slices sequence showed differences in the variation of ID (p<0.001), where the ID of 85 ms produced the most optimal image information.Conclusion: MRI image of the wrist joint of the T2 TSE FS SPAIR coronal slices sequence the most optimal with an ID variation of 85 ms compared to ID 70 ms and 100 ms.

Fluids of gastrointestinal system produce a high signal in 2D T2 Half-Fourier Acquisition Single-shot Turbo Spin Echo (HASTE) thick-slab MRCP which can overlap the biliary system image. This is the first experimental study use jasmine tea as oral contrast agent and aimed to evaluate it in improving the image quality of MRCP. This study was tested by phantom and healthy volunteers. Different types of tea phantom were tested which then calculated its signal-to-noise ratio (SNR) value and analyzed the manganese content. 15 healthy volunteers performed 2D T2 HASTE thick-slab MRCP scanning before and after administration of jasmine tea with a variation of 3 minutes, 6 minutes and 9 minutes scanning time. Qualitative analysis was carried out by MRCP questionnaire which was examined by radiologist and quantitative analysis was conducted by measuring the contrast-to-noise ratio (CNR) values. After jasmine tea administration, the image information was significantly different and CNR MRCP was increased compared to before giving negative oral contrast agent. The most optimal time to start scanning was 3 minutes after administration of jasmine tea with a volume of 300 ml (0.648 mg/dl manganese). Jasmine tea can be used as an alternative safe natural negative oral contrast agent and can improve MRCP image quality and reduce the intensity of gastrointestinal signals.

Struktur anatomi orbita sangat kompleks sehingga memerlukan detail yang baik pada msct scan untuk melihat patologi orbita. Salah satu parameter pada msct scan orbita untuk mengetahui keakuratan struktur anatomi orbita adalah ketebalan irisan. menurut literatur ketebalan irisan untuk orbital <2mm. Sedangkan literatur lain mengatakan 3-5 mm. Tujuan dari penelitian ini adalah untuk menganalisis informasi citra yang dihasilkan dengan variasi ketebalan irisan pada orbital ct scan.Metode penelitian ini menggunakan jenis penelitian kualitatif dengan studi eksperimen. Populasi dan sampel adalah 15 pasien dengan citra MSCT scan orbita dengan rekonstruksi ketebalan irisan media kontras potongan MPR aksial yaitu 1 mm, 2 mm dan 3 mm. Informasi citra yang dinilai adalah akurasi, kejelasan struktur dan jaringan pada citra ct scan orbita potongan MPR aksial meliputi anatomi tulang hidung, saraf optik, sinus etmoidalis, sinus sfenoid, tulang lakrimal, kornea, lensa, bola mata dan sklera. Pengambilan data dilakukan dengan cara observasi dan kuisioner kepada spesialis radiologi sebagai observer dan analisis data dilakukan dengan menggunakan SPPS uji Friedman test.Hasil dari penelitian ini yaitu terdapat perbedaan antara informasi citra pada variasi ketebalan irisan CT scan MPR aksial orbital dan ketebalan irisan yang dapat memberikan informasi anatomi yang optimal pada citra axial MSCT scan MPR orbital dengan media kontras yaitu 2 mm.Kata kunci : msct scan orbital; ketebalan irisanAbstract The anatomical structure of the orbit is so complex that it requires good detail on CT scan to see the pathology of the orbit. One of the parameters on the orbital ct scan to reveal the accuracy of the orbital anatomical structure is slice thickness. according to the slice thickness literature for orbital <2mm. Whereas other literature says 3-5 mm. the purpose of this study was to analyze the image information produced with slice thickness variations on ct scan orbitals. The method of this research is qualitative with a experiment study. Population and sample were 15 patients with orbital CT scan images with contrast media slice thickness reconstruction of axial MPR pieces that were 1 mm, 2 mm and 3 mm. Assessed image information is accuracy, clarity of structure and tissue on orbital ct scan images of axial MPR pieces including anatomy of nasal bone, optic nerve, ethmoidal sinus, sphenoid sinus, lacrimal bone, cornea, lens, globe and sclera.Data retrieval is done by observation radiologist and data analysis is carried out by SPSS Friedman test.The result of this research is there is a relationship between image information on slice thickness variations of axial MPR CT scans of orbital and slice thickness which can provide optimal anatomical image information on axial images of MPR CT scans of orbitals with contrast agent that is 2 mm.Keywords: orbital msct scan; slice thickness

Hemiarthroplasty is a surgical procedure to replace half of the hip joint with a prosthesis or artificial joint. The radiology procedure for the Hemiarthroplasty at Orthopaedic Hospital Purwokerto uses Antero-posterior projection of the pelvis. This projection is different from the routine projection, namely the Unilateral Antero-posterior Hip Projection. The purpose of this study is to determine the procedure for radiographic examination in cases of Hemiarthroplasty and to find out the reasons for using the Antero-posterior Pelvis projection to establish the patient's diagnosis. This type of research was qualitative with a case study approach. Data collection conducted in December 2020 at the Radiology Installation of the Orthopaedic Hospital Purwokerto, using the methods of observation, documentation, and interviews with radiographers and radiologists. Data analysis performed with primary data taken from one patient with Hemiarthroplasty. The patient has a history of fracture (broken bone) in the right side of the femoral neck before hemiarthroplasty surgery. The results showed that the proper projection for Hemiarthroplasty is the Antero-posterior Pelvis projection. The reasons were to see a comparison between the right and left hip joints and to find if there is a space or distance from the hip joints after the surgery procedure. Radiologists can get needed anatomical information about the pelvis by performing an Antero-posterior projection.
