Abstract

Background : Application of MRS itself to measure the N-Acetyl Aspartate (NAA) content in tumour, stroake and epilepsy. Contents of NAA has important role in the central nervous system. Examination of MRS itself should be included to support the patient diagnose. Time echo is an important parameter which affect the metabolite spectrum. So, measurement of metabolic value using variants of TE which is 35, 144, 288 ms, are the main idea. The purpose of this research to know the measurable metabolic which use of variants of TE and to know which TE has show the smallest difference with normal metabolic value.Methods : This research is a quantitative descriptive method. Reasearch subject is Radiographer which has competence dan enough experience in MRI. Research samples using 10 person who become the research probandus. The acquisition is do three times on right temporal lobe with TE value 35, 144 and 288 ms. Another parameter which controlled is TR 2000 ms, Single Voxel Spectroscopy (SVS) acquisition sized 31.7mm3 with Point Resolved Spatial Selection (PRESS) pulse sequence. Measurable metabolic aspect which will be evaluate is N-Acetyl aspartate (NAA), Choline (Cho) and Creatine (Cr). Data processing and analysis is do by calculate the spectroscopy spectrum intensity so obtained the measurable metabolic value then using univariate analysis or descriptive analysis.Results : Results of measurable metabolites is the longer TE use so the metabolic spectrum will be decrease on NAA (35 ms: 8.2, 144 ms: 7.3, 288 ms: 5.4), Cr (35 ms: 6.8, 144 ms: 5.8, 288 ms: 3.8) and Cho (35 ms: 6.9, 144 ms: 6.0, 288 ms: 4.4). Then on the calculate of metabolic value difference with normal metabolic value, the longer TE use so the difference will be increase on NAA (35 ms: 1.8, 144 ms: 2.7, 288 ms: 4.6), Cr (35 ms: 1.2, 144 ms: 2.2, 288 ms: 4.2) and Cho (35 ms: 0.1, 144 ms: 1.0, 288 ms: 2.6).Conclusion : So can be assumed that using TE 35 ms on MRS will obtain the metabolic spectrum which close to normal metabolic value. But, short TE unable to show the Lactate spectrum in case of brain tissue abscess, so it’s required to scanning using TE 35 ms and 144 ms or 288 ms as comparison to get more accurate measurable metabolic value.

Abstract

This research due to know the influencing factors of BNO-IVP radiograph rejection and to know the solution of rejection. The researcher using 3 method of data collecting, i.e. observational method which result the check-list of BNO-IVP rejected influencing factors, interview method which use to validate the data, and documentating method which result the data in photograph of BNO-IVP radiograph rejected. Then the data will be analysed with reject film analysis. Based on the method, the reject rate result on September up to 13,04%, on October up to 13,63%, then on November up to 29,26%. The influencing factors of BNO-IVP rejection i.e. un-cover anatomical region, poor of radiograph contrast, patient movement, fecal materials, and un-effectiveness of patient preparation. This research has been did on Department of Radiodiagnostic of RSUD Dr. Soetomo Surabaya using 12 BNO-IVP radiograph rejected of 41 total exams on November and then rated by 1 responden. Un-effectiveness of patient preparation is the result of this research. This factor is the main influencing factor of rejection up to 100%. Based on the researher analysis about the solution, i.e. increasing the communication to the patient about the BNO-IVP exam preparation and do revision to the patinet preparation form guide more simply, so the patient can understand easly.

Abstract

ABSTRACT Background: No data has yet been found regarding the evaluation of the use of Dose Constraints in a hospital radiology installation. The purpose of this study was to determine the percentage of adherence to the use of dose constraints in a radiology installation as well as analysis and follow-up. Methods: The research was conducted by making observations at 30 Hospitals on the island of Java, the researchers distributed a questionnaire survey in the form of 20 data using the exposure factor for Thorax PA examination which would then be inputted through the Si-INTAN application to obtain ESAK values. Results: Based on 600 data on the use of exposure factors from 30 samples of hospitals on the island of Java, it was found that 21 or 70% of the hospitals adhered to the use of dose constraints and as many as 9 or 30% of hospitals do not comply with the use of the determined dose constraint. Conclusions: Of the 9 hospitals that were not compliant with the use of the dose constraint, the highest ESAK value was obtained from RS-18, which was 0.939 mGy, which reached twice the stipulated I-DRL Thorax examination value. It can be seen that these hospitals used the most mAs. higher than other hospitals. The mAs values used range from 10-28 mAs. When compared with the lowest ESAK value, namely RS-3, it only uses 5 mAs for an adult thorax examination. to suppress ESAK doses to be lower we can use high tube voltages. to obtain an exposure with the same transmission at a patient thickness of 20 cm, namely by increasing one of the irradiation parameters of the tube voltage value by compensating for a decrease in the tube current-time value to produce an image density that is almost the same,and using very low mAs also results in a dose radiation is very small.
