Abstract

Background: Thorax Multi-slice computer tomography (MSCT) scan examination requires contrast medium to image the difference in density with the surrounding tissue. The contrast images is largely determined by the volume of contrast, injection rate and injection methods. Thorax CT scan is performed by slice thickness of 5-10 mm. Meanwhile, it should use the routine slice thickness of 10 mm. Slice thickness of 8-10 mm of coronal and sagittal images require reconstruction by thin slices of 1-1.5 mm and subsequently by applying 3D. Aims: This is to analyse the volume of contrast and slice thickness used in the examination of tumor mediastinum by thorax MSCT examination. Methods: This research used descriptive qualitative design with case study approach, described and explained systematically, related to the procedure of Thorax MSCT examination technique in the case of mediastinum tumor with 3 samples of 3 patient and assessment performed by three radiologist as respondents. Results: This study indicates the success of the use of proper contrast of 80 cc and slice thickness of 2-3 mm to observe lesions of mediastinal tumor. Conclusion: Thorax MSCT examination in the case of mediastinum tumor should use contrast 80 cc and slice thickness of 2-3 mm to observe lesions of mediastinal tumor and coronal and sagittal axial slices, because the sagittal slice can show the lymphadenopathy enlargement so that the mediastinum tumor is clearly visible. The print out or filming results should be included the MPR or 3D to show the presence or absence of bone destruction and metastases.

Abstract

Several unique things differentiate radiographic examinations in pediatrics from adult patients, including patient fixation, the level of patient cooperation, and the need for patient companions. Currently, no literature provides an overview of the patient's age with these three aspects of radiographic examination. This study aims to provide an overview of the relationship between age groups and the implementation of radiographic examinations, which greatly influence the success of the examination. This research is a type of descriptive observational research. Data obtained from three hospitals was collected for one month. The sample for this study was 144 pediatric radiographic examinations. The study results are described in frequency distributions related to patient fixation, level of patient cooperation, and the need for patient companions. The study results showed that patients began to cooperate, and the use of fixation decreased in the age group of three years and above. Patients begin not needing a companion at six years and above. The radiographer must evaluate these three things to prepare the examination with an appropriate approach with the goal of a successful exam without repetition so that the radiation dose is minimal for both the patient and the patient's family. This research can be used as a guide for radiographers in preparing for examinations and initial communication during pediatric radiography examinations.

Abstract

Panoramic dental radiography uses X-rays to produce radiographs of the jaw and facial structures, from the teeth to the TMJ and the entire dental arch. Exposure to X-rays during an examination can be problematic because sensitive areas such as the thyroid gland and eyes adjacent to tooth structure also receive radiation exposure. Patients in panoramic examinations do not use eye radiation protection equipment for the orbit, namely Pb glasses, while the eyes are close to the dental arch which can receive radiation exposure, so eye radiation protection equipment is needed in panoramic examinations for patient safety. The aim of the research is to determine the function test and performance test of the Eye Radiation Protection Device.This type of research is quantitative research with an experimental approach. The research sample was 3 patients with variations of 3 kV: 70, 76, and 86 kV with a setting of 10 mA. The radiation dose to the eye was measured using a phantom and pocket dosimeter before and after using the radiation protection design tool, then looking for the average, difference and percentage and carrying out the Kruskal-Wallis spss test.The results of the three radiographs showed no artifacts, the exposure factor before using the device was 70 kV = 0.08 mSv, 76 kV = 0.17, 86 kV = 0.27 mSv while the radiation dose received after using the device with an exposure factor of 70 kV = 0 mSv, 76 kV = 0.86 kV = 0.003 mSv, while from the Kruskall-walls statistical test pre-test and post test kV 70 shows a significant value of 0.034 0.05, kV 76 does not show a significant value of 0.121 0.05, kV 86 shows a significant value of 0.043 0.05. The design of this eye radiation protection device has succeeded in reducing or reducing the radiation dose around the eyes by up to 100%. Meanwhile, the level of feasibility of the tool has a respondent score of 80%. Suggestions for using a thermoluminescence radiation measuring instrument (TLD) with smaller units, namely µSv.

Abstract

Background: Ischemic stroke is a critical condition detectable through head CT scans, where windowing techniques significantly enhance brain tissue visualization. At Bethesda Hospital Yogyakarta, differing windowing protocols are used in the Emergency and Main Radiology Departments, yet no standardized stroke-specific window has been established. This study aims to identify the differences in anatomical information in head CT scans with various windowing settings and to determine the most optimal windowing protocol.Methods: This research is a quantitative-experimental study conducted at Bethesda Hospital Yogyakarta involving 10 patients with ischemic stroke, using variations of windowing settings: WW 120 HU WL 60 HU, WW 100 HU WL 35 HU, and WW 40 HU WL 40 HU. The image results were evaluated by two respondents based on the anatomical information of brain parenchyma, insular cortex, internal capsule, left and right cerebral hemispheres, and brain sulci. The data analysis was performed using the Friedman statistical test.Results: The results of the study showed that the WW 100 HU WL 35 HU setting provided the most informative anatomical visualization across all evaluated brain structures. In contrast, WW 120 HU WL 60 HU was the least informative for the brain parenchyma and insular cortex, while WW 40 HU WL 40 HU offered moderate clarity for most structures but was suboptimal for the brain parenchyma. These differences were confirmed by the Friedman test, with a p-value 0.05.Conclusions: There were differences in anatomical information across the various windowing settings in head CT scan examinations for ischemic stroke cases. In addition, the highest overall and individual anatomical mean rank was found in the WW 100 HU WL 35 HU windowing setting, with a value of 2.95.

Abstract

The increasing use of radiation in health services increases the risk to the public. The radiology study program as a producing institution has the challenge of ensuring that students fully understand and are aware of radiation safety. This study aims to determine the level of knowledge and awareness regarding radiation safety and related factors among radiology study program students.This was a quantitative study with a survey approach. The study instrument was a questionnaire that was delivered to 140 students from 7 radiology study programs in Indonesia consisting of 2 state institutions and 5 private institutions. The questionnaire consisted of 12 questions to evaluate knowledge regarding radiation safety, 16 questions to evaluate awareness regarding radiation safety and 6 questions to evaluate the learning experiences.Based on the study results on knowledge regarding radiation safety, 12.86% of respondents had "Poor" level of knowledge, 35.00% of respondents had "Moderate" level of knowledge, 20.71% of respondents had "Good" level of knowledge and 31.43% of respondents had "Very Good" level of knowledge. Respondents' radiation safety awareness in the "Poor" category was 3.57%, "Fair" 17.14%, "Good" 43.57% and the "Very Good" category 35.71%. Laboratory practical experience and the completeness of laboratory infrastructure had a positive effect on students' knowledge regarding radiation safety. Furthermore, clinical practice experience similarly had a positive effect on awareness regarding radiation safety. The study outcome can be applied as input for radiology study program educational institutions in developing learning to achieve competency regarding radiation safety.
