Abstract

Background: GRAPPA or Generalized Auto-calibrating Partially Parallel Acquisitions is a parallel acquisition technique which can reduce the scan time in MRI examination. Aims: This study aims to investigate the effect of the R-factor variation of GRAPPA on image anatomical information quality and to determine the optimization value of GRAPPA e-factor to fasten the scan time with acceptable image information quality. Methods: Eight respondents will perform T2 axial Brain MRI examination with various values of GRAPPA R-factor (1 to 7), evaluation was conducted with questionnaire which was given to 3 radiologists to assess the anatomical structure of the lateral ventricle, thalamus, caudate nucleus, lent form nucleus, internal capsule and background area. Data from respondents were then tested with Spearman test and Friedman test. Results: Statistics test showed that there was significant effect of GRAPPA parallel acquisition technique on the anatomical image information quality of T2 axial Brain MRI (p value of 0,001<0,05) and the correlation direction was negative, in which the higher the value of r-factor GRAPPA used, the lower the quality of anatomical image information. Based on the result of mean rank, image with optimal image anatomical information quality was image with GRAPPA R-factor of 1 (mean rank = 6.01), but image anatomical information quality with GRAPPA R-factor of 3 was acceptable with fast scan time (opinion of 75 % of all radiologists). Conclusion: R-factor at GRAPPA parallel acquisition technique could reduce scan time, but the higher the value of r-factor GRAPPA used, the lower the quality of image anatomical information.

Abstract

The major drawback of the parallel periapical examination technique is that the holder used can damage the oral tissues and cause discomfort to the patient. The objective of this study is to determine the work efficiency and radiographic quality of the innovative dental x-ray holder which has been made by adding synthetic rubber or silicone to the part of the holder that is in direct contact with the patient. This research is an experimental with a post-test only design. The analysis was performed based on filling out the questionnaire on a Likert scale ranging from 1 to 4. With the criteria 1. Disagree, 2. Sometimes, 3. Agree and 4. Strongly Agree. The test was administered by comparing the holder made with the commonly used Aphrodite holder as a control group. There were 16 repetitions of exposure to the cadaveric skull in obtaining research data for each treatment group. The results of statistical work efficiency testing on the control group resulted in a value of B = 0.125 with a significance of 0.071 and an effect of 10.5%. Meanwhile, for testing the quality of radiographic image, the value of B = 0.125 with a significance of 0.014 and an effect of 18.5% was obtained. The innovative dental x-ray holder using a silicone rubber layer is efficient and the resulting radiographic image quality is good when used in the intraoral examination.

Abstract

The CT Scan examination technique that in the last decade is popular in diagnosing urinary stones is NCCT Urography examination. This examination is fast and informative, but this examination has a deficiency that the resulting image has a fairly high noise. Iterative Reconstruction is a method of algorithm reconstruction on CT Scan with the basic principle of estimating data to produce reconstruction image by reducing noise. The purpose of this study was to find out the difference in noise value in the use of Iterative Reconstruction in reducing noise and improving the quality of NCCT Urography image. This research was conducted retrospectively, namely on existing image given iterative reconstruction treatment of 20%, 40%, 60%, 80% and 100%. Samples in each iterative reconstruction treatment group as many as 10 images. Image is done noise measurement by doing ROI in kidneys, ureter and VU. Data analysis is done by conducting different tests of One Way Anova using SPSS Software. The results showed that there was a significant difference in noise value after it was done Iterative Reconstruction. Noise decreased as the percentage of used Iterative Reconstruction increased in NCCT Urography image. In the use of Iterative Reconstruction percentage of 100% obtained the lowest average noise value of 9.11. The use of Iterative Reconstruction can reduce noise in NCCT Urography image by 9.386% compared to Filtered Back Projection (FBP). Iterative reconstruction is able to reduce noise and improve the image quality of NCCT Urography.

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

Program kendali mutu merupakan salah satu syarat dalam perizinan pemanfaatan sinar-X di Indonesia. Namun, hampir 70% fasilitas pelayanan kesehatan yang terkendala dalam kegiatan tersebut yang disebabkan dari berbagai aspek, mulai dari harga alat uji yang terlalu mahal dan belum optimalnya program kendali mutu. Tujuan untuk memberikan pengetahuan dan meningkatkan keterampilan kepada radiografer agar dapat melakukan program kendali mutu sesuai Peralatan yang digunakan di pelayanan radio diagnostik tempat bekerja. Program ini dilakukan pemberian materi, praktikum, pendampingan program kendali mutu dengan menyesuaikan peralatan yang dimiliki fasilitas pelayanan radio diagnostik dan evaluasi. Hasil menunjukkan bahwa tingkat pemahaman peserta terkait program kendali mutu terjadi peningkatan dengan skor rata-rata  pretest  46,67 naik menjadi 79,44 saat post pest. Kenaikan skor sebesar 70,21%. Pendampingan program kendali mutu efektif dalam peningkatan kemampuan radiografer dalam program kendali mutu pelayanan radiodiagnostik dengan rerata skor peningkatan pemahaman adalah 32,77.
