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.
Background: To be able to show the Lung anatomy in detail in CT Scan Thorax lung window then required sharp image quality. One way to improve image sharpness is to use kernel settings. The purpose of the research is to know the difference of the quality of the 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 best Methods: Type of research is an experiment. The study was conducted using a CT image scan of the 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 radiologists 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 variables 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 the kernel variations of B50s, B60s, B70s, B80s, U90s. The kernel that generates image detail for CT thorax lung windows is the U90s kernel.
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 180 0 and 360 0. 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 Termoluminisencedosemeter (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 180 0 and 360 0. 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 180 0 , and with shielding 360 0 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 180 0 , and a decrease of 62.94% when shielded 180 0. Conclusion:Lead apron is effective for reducing radiation dose on breast in abdominal CT. 360 0 shielding provides higher reduction than 360 0 shielding, so it can be considered to be applied in clinical procedure.
