Backgroud: Brain MRI examination generally has a long scanning time because many protocols that must be used, one of them is DWI sequences, which are sequences that can provide pathological information on the brain. One way to reduce scan time is to use parallel imaging sensitivity encoding (SENSE) techniques. SENSE utilizing the spatial information RF coil phased array to reduce the acquisition time by reducing the number of sampling lines K space therefore produce quality and good spatial resolution, but its has the limitations, namely the reduction of SNR. The purpose of this research was to analyze in SNR on the variations of SENSE value in MRI brain DWI axial slices.Methods: This research is a quantitative study with an experimental approach in 15 patients MRI Brain. Data was taken by calculating the SNR value for the region of interest (ROI) in cortex cerebri, basal ganglia, thalamus, pons and cerebellum, and then ROI in noise background. Data was analyzed through Repeated Measures Anova test by comparing the differences in SNR values obtained in MRI brain DWI axial between the use of various SENSE values, that are 2.0; 3.0 and 4.0.Results: MRI image of DWI axial brain sequence with variation of reduction factor 2.0; 3.0 and 4.0 cause different SNR values. The highest SNR is found in the variation of 2.0 and the lowest value is 4.0 but the scan time is fastest at the 4.0 variation This is because there is a reduction in the phase encoding line in the K-space on each image using SENSE and the higher the reduction factor, the higher the reduction factor. SNR will decrease.Conclusion: The higher the value of SENSE variations will decrease the SNR value but the scan time is faster.

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.

Penelitian ekperimen ini menggunakan 3 variasi kV yaitu 80 kV, 110 kV dan 130 kV, masing-masing nilai kV diberi perlakuan menggunakan automatic exposure control dan tanpa menggunakan automatic exposure control. Hasil penelitian yang didapat yaitu ada perbedaan nilai dosis radiasi dan image noise anatar penggunaan automatic exposure control dan tanpa penggunaan automatic exposure control, dimana penggunaan automatic exposure control dosis radiasi yang dihasilkan jauh lebih rendah dibandingkan tanpa penggunaan automatic exposure control. Sedangkan untuk nilai image noisenya, penggunaan automatic exposure control menghasilkan nilai image noise lebih tinggi dibandingkan tanpa penggunaan automatic exposure control. Sehingga penggunaan automatic exposure control ini dapat menurunkan dosis radiasi yang diterima objek tetapi juga meningkatkan image noiseKata kunci: Image Noise, Dosis Radiasi, AEC Abstract Radiation dose is something that needs to be considered in a CT scan. On the CT Scan aircraft there is automatic exposure control software that functions to determine the mAs value automatically which is adjusted to the thickness of the object, so that it is expected to reduce the radiation dose received by the object. This experimental study uses 3 variations of kV, namely 80 kV, 110 kV and 130 kV , each kV value was treated using automatic exposure control and without using automatic exposure control. The results obtained are that there are differences in the value of radiation dose and image noise between the use of automatic exposure control and without the use of automatic exposure control, where the use of automatic exposure control produces a much lower radiation dose than without the use of automatic exposure control. As for the image noise value, the use of automatic exposure control results in a higher image noise value than without the use of automatic exposure control. So that the use of automatic exposure control can reduce the radiation dose received by the object but also increase image noiseKeywords: Image Noise, Radiation Dose, AEC
