Abstract

Background: Radiation Protection Officer (PPR) plays an important role in ensuring radiation safety supervision in diagnostic and interventional radiology facilities. To support this, high level competencies are absolutely necessary. The purpose of this competency analysis study is to obtain an overview of the competence of radiation protection officers working in diagnostic and interventional radiology facilities. Methods:  This study is a descriptive as well as quantitative research. The study was conducted by collecting primary data through filling out questionnaires with an assessment by 6 inspectors with respondents assessed as 40 PPR from 40 diagnostic radiology facilities spread across West Java, East Java, Batam, Riau Islands. Validity and Reliability testing was carried out in this study. PPR competency level analysis was carried out by testing statistical descriptions and testing the frequency distribution using Statistical Product and Service Solution (SPSS) for windows 21.Results: The results of PPR competence in 40 diagnostic and interventional radiology facilities by 6 Nuclear Safety Inspectors showed that the level of PPR competence in diagnostic radiology facilities was at a high level. This is related to the selection of nuclear safety inspectors who are in the (good) and (very good) rangeConclusion:  Based on the computational analysis using the SPSS version 21 program, it shows that the level of hard competency (technical competency) and soft competency of PPR in diagnostic and interventional radiology facilities is at a level above 3 or the average is at a level close to high. Further research needs to be done with a more comprehensive competency statement item variable and with a larger number of inspectors and PPR with a research time span long enough in order to describe the actual PPR competencies on the field.

Abstract

Background: On radiographic examination, the direction of the beam affects the anatomical image of the object produced. Pedis examination of the AP projection  is a radiographic examination that uses two directions of beam. The direction of beam is with and withhout X-ray tube angulation.  This research aims to compare radiograph anatomy information with and without X-ray tube angulation on pedis examination of the ap projection.Methods: This type of research is qualitative research with a descriptive approach. Data was obtained by making radiographs using  with and without X-ray tube angulation using object phantom. The radiographic imaging of the pedis were observed by ten respondents, consist of radiology specialist t and resident radiology specialist, by giving questionnaires. Then the data obtained will be processed by being described and analyzed.Results: The result of the research showed different of x-ray tube angulation on the pedis examination on AP projections is the use of 100 angles because they get a high score. As well as the use of angle 100 chepalad can visualize both the interphalangeal joint space, metatarsophalangeal joint space, tarsometatarsasl joint space, joint space between the navicular and cuneifrome appear open, navicular, and cuboid. While the use of an angle of 00 can show the sesamoid bone and three cuneiform bones quite well. The angle of the beam direction is 100 chepalad so that the direction of the beam is perpendicular to the metatarsal bone so that there is no distortion in the metatarsal bone image. If the case is a fracture without having to prioritize the joint space, then the examination without an angle can be done because it is easier and saves time.Conclusion: AP projection of the pedis radiograph with the use of an angle 100 chepalad and without the use of posterior tube angulation  with the posterior beam toward the heel produces different anatomical information. The most optimal anatomical information is generated by the use of a 100 chepalad.

Abstract

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.

Abstract

Introduction: Quality and dose factors are very important in radiodiagnostics. To produce a constant radiographic quality, the density and contrast produced must remain constant. There is a rule that aims to produce a constant radiographic quality by adding the exposure value, namely the 10 kV rule. This study was conducted to determine the noise in the computed radiography image with the thorax organ produced by modifying the exposure factor of the 10 kV rule and whether it is still within tolerance.Methods: This quantitative research was conducted with an experimental approach. This is done by taking a series of radiographs that include three exposure factor settings, standard (60 kV, 10 mAs), increased by 10 kV (70 kV, 5 mAs) and lowered by 10 kV (50 kV, 20 mAs). Noise measurement is done by doing ROI in the background area. The exposure index and deviation index values were also recorded as quality and dose references. The data was processed and analyzed by statistical tests.Results: From the statistical test results, there is a significant relationship between kV and noise with a sig (1-tailed) of ,000. Noise on the standard exposure factor has a lower noise than the modified exposure factor with a difference of 0.2. From the quality aspect, the most optimum exposure index and deviation index indicators are in the range of 70 KV and 5 mAs.Conclusion: The results of the statistical test of the relationship of kV to noise obtained at 50 Kv and 20 mAs, 60 kV and 10 mAs gave a significance value of 0.263 and 0.435, while at 70 kV and 10 mAs with Sig. (1-tailed) of .000 which means the relationship between kV to noise is strong because the sig value is below 0.05.

Abstract

Backgroud: MRCP is a non-invasive imaging examination, which is used for the evaluation of biliary tract, pancreatic duct, and gallbladder. Pulse sequences which can be used to visualize organs in MRCP on T2 weighting is using a fast pulse sequences such as sequences TSE or Haste. The purpose of this research was to knowing the difference image information between T2 axial TSE with Haste and where better to use between the two sequences on axial T2 MRCP examination.Methods: This type of research is experimental observational approach, it has been carried out in the best MRI 1.5 Tesla at RSU Haji Surabaya. Sample used were 5 patients. Each patient performed two pieces of axial T2 sequences in which the TSE and Haste. Furthermore, the image submitted to the three doctors radiologist to fill out a questionnaire that has been provided to assess the image consisting of the liver, gallbladder, common bile duct (CBD), pancreas, intrahepatic duct and an assessment of the artifacts.Results: The results of analytical assessment Wilcoxon test, for the entire anatomy with ρ value of 0.002 which means that ρ 0.05, and the artifacts show the ρ value of 0.006, which means ρ 0.05. This proves that there are differences in image information between T2 axial TSE with T2 axial Haste the MRCP examination. At each of anatomy, liver has ρ value of 0,071 (ρ 0.05), gallbladder has ρ value of 0.317 (ρ 0.05), CBD has ρ value of 0.003 (ρ 0.05), pancreas has ρ value of  0.014 (ρ 0.05) and intrahepatic duct has ρ value of 0.004  (ρ 0.05). Based on the mean rank statistical test results show sequence Haste better in generating image information on the whole anatomy, but in each of anatomy based on the mean rank of gallbladder both sequences are equally good in showing gallbladder, whereas to display the liver, CBD, pancreas, and intrahepatic duct, the results showed T2 Haste mean rank better, it is because it has the characteristics of high Haste T2 signal intensity and better in reducing motion artifacts.Conclusion: Wilcoxon test analysis results expressed Ha accepted, meaning that there is a difference between the image information pieces axial T2 TSE with Haste the MRCP examination. The mean rank shows Haste superior to TSE, this is because the artifacts on TSE and therefore contributes to the respondent's assessment, other than that Haste has a high signal intensity so that it can show more clearly ducts.

Abstract

Background: A brain tumor is a mass of brain cells that grow abnormally. In radiological terms, a brain tumor is called a space occupying lesion (SOL) which generally means a lump. Radiologists or radiology specialists in identifying brain tumors will analyze the results of Magnetic Resonance Imaging (MRI) Brain images with post-processing techniques using a menu in a 3D editor called the region growing technique.Methods:This type of research is a quasi-experimental research design using Posttest Only Without Control Group Design. The research plan will be carried out at Hermina Hospital Bekasi using 32 samples of brain tumor MRI images, the sample size is obtained by the sample size formula for two paired populations according to Sastroasmoro (2011). Bivariate data analysis, if the data is normally distributed (p value 0.05), then the Paired T-test statistical test is performed and if the data is not normally distributed (p value 0.05) the Wilcoxon statistical test is performed.Results: The results of the analysis of brain tumors are followed by manual measurement of tumor volume using the region growing technique. It requires sufficient expertise and experience so that the diagnosis of tumor volume is given precisely and accurately so that its handling can be carried out wisely Evaluation of MRI images requires high accuracy, but doctors can make mistakes because the diagnosis is still done manually, such as errors in diagnosing the location of the tumor and the size of the object. The very complex structure of the human brain also presents its own difficulties in identifying brain tumors. Subjective factors can also affect manual doctor evaluations such as fatigue and uncontrolled time in evaluating an MRI image so that a digital image processing program is needed that can be done with a computational machine to assist doctors in evaluating an MRI image automatically. The active contour method can solve the problem of topological changes in a brain tumor image.Conclusion: The active contour method is able to classify images with high accuracy. So that it can increase the accuracy of the segmentation process for easy and fast medical diagnosis. The calculation of the volume of brain tumors can be done using the binaryization method which has been segmented through the final image produced by the active contour method. Tumor segmentation and automatic tumor volume calculation have great potential in clinical treatment by freeing doctors from the burden of manual labeling, digital image processing of brain tumors using the active contour method can be used as a complement to the MRI modality that radiologists can use in calculating brain tumor mass volume calculations
