Abstract

Background: To be able to show the Lung anatomy in detail in CT Scan Thorax lung window then required a sharp image quality. One way to improve image sharpness is to use kernel settings. The purpose of research is to know the difference of the quality of anatomical image with kernel variation CT Scan Thorax Lung Window and know the proper kernel selection to produce CT scan of thorax lung windows the bestMethods: Type of research is an experiment. The study was conducted using a CT image scan of thorax on axial lung window slices in cases of lung tumors in the kernel B50s, B60s, B70s, B80s, and U90s. The research was conducted by measuring the CT image quality of thorax scan on the windows lung by way of questionnaire assessment to 5 radiologist as the observer to CT Scan image to determine the level of clarity of anatomical criteria.Results: The results showed that there were significant differences in the quality of anatomical imagery with kernel variation of B50s, B60s, B70s, B80s, U90s with p-value 0.05. CT images can thorax lung windows that have the best anatomical image quality of the samples taken are shown by the use of the kernel U90s.Conclusions: There are significant differences in the quality of anatomical imagery with kernel variation of B50s, B60s, B70s, B80s, U90s. The kernel that generates image detail for CT thorax lung windows is the U90s kernel

Abstract

Backgroud: Previous researches show that the use of out of plane shielding can reduce the radiation dose received by radiosensitive organs around the scan area on CT scan. There is a special shielding designed for CT scans, but currently the type of shielding available in almost all radiology installations is the lead apron. This study aims to determine the dose received by the breast area on CT abdominal scan without shielding and its reduction by giving lead apron shielding on 1800 and 3600.Methods:This is quantitative research with a pre-experimental design. Abdominal CT scan was performed on a whole body CT phantom whose characteristics are close to human body tissue. The radiation dose received by the breast area was measured by Termoluminisence-dosemeter (TLD). TLD’s were placedon the same points. Scanning was performed using Siemens Somaris/5 Syngo, repeated in three conditions: without shielding, lead apron shielded (equivalent to 5 mm Pb) by 1800 and 3600. The rouitne protocol was used (120 kv and 200 mA) Data was analyzed by Paired t-test to determine the difference in radiation dose received and descriptive analysis for know the level of reduction.Results:The radiation dose received by the breast area without shielding, with shielding 1800, and with shielding 3600 were respectively 0.653 mSv, 0.367 mSv, and 0.242 mSv. There were significant differences in the dose received by the breast area (p value 0.05) by using shielding. Compared to unshieldied condition, there was a decrease of 43.95% when shielded 1800, and a decrease of 62.94% when shielded 1800.Conclusion:Lead apron is effective for reducing radiation dose on breast in abdominal CT. 3600 shielding provides higher reduction than 3600 shielding, so it can be considered to be applied in clinical procedure.

Abstract

Background: In CR, there is an indicator called Exposure Index (EI) which displays how much exposure is used for a particular examination. The Exposure Index depends on the exposure factor, the total area of the detector exposed to radiation, and the object being exposed (Bontrager Lampignano, 2014). One of the exposure factors that is often regulated by the radiographer is mAs. Milliampere seconds (mAs) determine the number of X-rays produced. The purpose of this study was to determine the differences in the Exposure Index Values on Chest Radiography with Changes in the Combination of Different mA and s Values at the Same mAs Value.Methods: This research is a type of quantitative research with a pre-experimental design. The object of this research is the thorax phantom. Data were collected by exposing thorax the chest phantom, then recording the resulting Exposure Index value. mA and s value variations that are set are 25mA x 320 ms, 160mA x 50 ms and 400mA x 20ms. Data analysis was carried out using statistical tests.Results: From the statistical test results it is known that there is no significant difference in the Exposure Index Value on Thorax Radiography between the 25mA x 320 ms combination group, the 160mA x 50 ms combination and the 400mA x 20ms combination with a p-value 0.05 (p-value = 0.151) . The reason for the absence of a difference in the Exposure Index value is the variation in the combination of different mA and s values for the same mAs because with the same mAs, the quantity / intensity value of the X-ray radiation produced is also the same or there is no increase or decrease. With the same x-ray radiation intensity, the radiation received by the Imaging Plate is also the same so that the value of the Exposure index is also the same.Conclusions: There is no significant difference in the Exposure Index Value on Chest Radiography with Changes in the Combination of Different mA and s Values at the Same mAs Value

Abstract

Background: Betel leaf oil is a wonderful natural antiseptic. Betel leaf oil is rich in polyphenols, especially chavicol, which can be used to protect against microbe pathogens that cause infection. The cause of the spread of nosocomial infections in radiology can occur using a radiographic cassette. Previous research has found that radiographic cassette contains microorganisms and fungi. Purpose: To determine the effectiveness of using betel leaf oil as a natural disinfection on a radiographic cassette. Method: Quasi-experimental research with pre-test and post-test design designs was carried out by calculating the number of microbes, including Total Plate Count (TPC), Staphylococcus, and fungi. The study on 12 conventional radiographic cassettes was calculated using the swab method before and after cleaning with betel leaf oil. The data were analyzed descriptively to illustrate the rate of decline. Result: The results showed that the percentage rate of decline after the radiographic cassette was cleaned with betel leaf oil was ALT (17.8%), Staphylococcus (57.41%), and fungi (37.21%). Conclusion: Betel leaf oil can be used as alternative natural disinfection on radiographic cassettes, quite effectively suppressing the activity and number of microbes present.

Abstract

Background: Radiation protection is very important for patient and personnel safety in radiology services. It has been given in the college through classical lectures, including in Radiodiagnostic and Radiotherapy Department Poltekkes Kemenkes Semarang. The student’s knowledge is routinely evaluated but their compliance in the clinical activities has never been specifically observed. This study aims to find out the relationship between knowledge toward compliance of the application of radiation protection on clinical practice students.Methods: This is quantitative research with a cross-sectional design. Research was conducted on 90 second-year clinical internship students of the Radiodiagnostic and Radiotherapy Department. The level of knowledge was measured by written test, while the level of compliance was observed by clinical observation. The affecting factors are investigated through indepth interview. Data were analyzed by Spearman Rank Correlation.Results: The knowledge levels among the students were "excellent” (18%), "good" (68%), and "fair" (14%). The radiation protection compliance levels were "good" (73%) and "very good" (27%). There was a significant relationship between radiation protection knowledge level toward radiation protection compliance (p value 0.05). The strength of the relationship was low (coefficient interval = 0.257). Conclusions: There was a relationship between knowledge and the level of compliance, but it was not the only influencing factor. The environment tends to have an effect on the level of compliance. Radiographers and clinical instructors should be good role model in applying radiation protection.
