Abstract

Background: Computed Radiography has an exposure index that used as an exposure indicator. But on radiographic examination, exposure index value  sometimes ignored, and in  the preliminary survey of pediatric chest examination resulting a large exposure index range. The aim of this study is to know the profile of exposure index value and the setting of the exposure factors, the assessment of anatomy criteria and technical aspect, and the right exposure factors such as kV and mAs on pediatric chest examination.Methods: The type of this research is descriptive quantitative. The research was done by collecting data related to pediatric chest radiograph (≤ 2 years) the value of exposure index was recorded, then the radiograph was assessed using questionnaires that filled by one respondent who is a radiologist. The data was analyzed by displaying the data of exposure index and anatomy criteria from questionnaires into the table form, and then conducted a descriptive analysis to be drawn conclusions.Results: The results showed the profile of exposure index value and the setting of the exposure factor  has a fairly large exposure index range of 1084 – 2175, using 40 kV and 10 mAs and the collimation still often exceeds the object. Then for the assessment of the thorax anatomical criteria and the technical aspect overall was “Good Enough”, and the right exposure factors, that is: at 6 and 7 cm chest thickness was using 60 kV and 1,6 mAs; at 11 cm chest thickness was using 60 kV and 2 mAs, FFD 100 cm, and the setting of collimation as wide as object, the exposure index generated in the normal range that is 1251 – 1382.Conclusion: The right exposure factors on pediatric chest examination, that is: at 6 and 7 cm chest thickness was using 60 kV and 1,6 mAs; at 11 cm chest thickness was using 60 kV and 2 mAs, FFD 100 cm, and the setting of collimation as wide as object.

Abstract

Background: Stroke is a brain disease where an acute nerve function is occurred due to the cerebral vascular disorders. To establish a diagnosis the stroke, it can be identified by employing the Diffusion Weighted Imaging (DWI) sequence in the MRI examination. Artifacts still exist on the MRI image which in turn reduce the resolution when using the DWI sequence. Adding the PROPELLER data acquisition method in the DWI sequence possibly improves the quality of brain images. The purpose of this study is to know the difference on the quality of anatomical image information between the DWI sequences with PROPELLER and without PROPELLER methods, and to determine adequate anatomical image appearance that created in amongst of the two methods, specifically for the stroke disease.Methods: this research is quantitative research with experimental approach. This study was conducted using MRI 1.5 T at Bethesda Hospital Yogyakarta. Data were 16 images from 8 patients using DWI sequences using PROPELLER without PROPELLER on MRI Brain examination with stroke. The results of the image were evaluated on 7 criteria: cortex cerebri, basal ganglia, thalamus, pons, cerebellum, stroke (infarction) and artifacts using questionnaires given to 3 respondents. Data analysis was done by Wilcoxon test to know the difference of anatomical image information on DWI sequence using PROPELLER without PROPELLER and to know better anatomical image information from both sequences seen from mean rank value.Results: The results shown, there is a significant difference on the quality of anatomical image information and the artifacts between the use of DWI sequence with and without PROPELLER methods ( 0.05). Based on the mean rank results, the DWI PROPELLER sequence has a higher mean rank value 4.50 compared to the DWI sequence without PROPELLER 0.00.Conclusions: The DWI PROPELLER sequence has better image results compared to the DWI sequence without PROPELLER.

Abstract

Background: All acts of radiation use, both for diagnostics, therapy and nuclear medicine, must go through a process of justification, limitation and optimization so that patients, officers and the surrounding environment get as much diagnostic benefit as possible with the smallest possible radiation risk. Some problems that arise in the Hospital / clinic, often ignore and do not pay attention to work exposure safety factors. The purpose of this study was to determine the profile of occupational radiation exposure and the effectiveness of radiation shielding in the radiology department of the Semarang city  then compared to the reference dose to determine the optimization of radiation protection.Methods: The type of research conducted is quantitative research with a survey and observational approach. Exposure measurements were carried out in 5 radiology department, which included 3 hospitals and 2 clinical laboratories. Documents and room observations are also carried out. For the effectiveness of the radiation barrier it is also measured before and after the radiation shielding by using a  surveymeter tool. The results data are then presented in descriptive analyses.Results: The results of the study of radiation exposure profiles in five radiology institutions, four institutions there was radiation exposure recorded on the  surveymeter tool, with the largest exposure value was 0.099 mSv / h (still below the safe limit of 1 mSv / year). Only one hospital is safe, and there are no leaks.Conclusions: The effectiveness of the radiation retaining wall, four hospitals have a barrier level equal to 1 mm Pb at 80 kVp irradiation, and 1 hospital (RSJ) has a radiation barrier equivalent to 0.5 mmPb.

Abstract

Background: Tube voltage (kVp) is one of the exposure factors on a head CT scan that can be varied to achieve a minimal radiation dose. Radiology installation of Bhakti Wira Tamtama hospital has a new CT scan modality that never variation its tube voltage. The variation of tube voltage is 80 kVp, 100 kVp, and 120 kVp. The aim of this research is to know and to analyse the most optimize tube voltage which can produce the best anatomy clarity and has the lowest radiation dose on a head CT scan examination of the base skull area that dominates CT scan examination.Methods: This research is descriptive analytic research conducted with an experimental approach. The study was conducted by varying the tube voltage to be used for head CT scan examination. There are 3 variations of tube voltage 80 kVp, 100 kVp, and 120 kVp where one variation contains 16 images for analyzing the clear anatomy of the base skull area. Then assessed by radiologists as the respondent. Data was analyzed by scoring where score 1 is not clear, score 2 is clear and score 3 is very clear. Radiation dose was obtained from CTDI and DLP records.Results: The results showed that there is no difference in anatomy clarity between variation of three tube voltage with p value 0,135. The anatomical clarity assessed includes anterior skull base, central skull base (fossa cranial middle, sphenoid, temporal bone, petrosous ridge), anterior clinoid processes, posterior margin of the lesser sphenoid wings, anterior and superior rim of the greater sphenoid wings, mastoid, and posterior skull base. All of them is very clear at 100 kVp and 120 kVp with value 100%. But at 80 kVp assessed clear at anterior and posterior skull base. So the value of anatomy clarity at 80 kVp is very clear only 71%. The effect of the difference in tube voltage on the radiation dose on a head CT scan of the base skull area showed a difference in the decrease in radiation dose from 120 kVp to 100 kVp for CTDI 39.9% and DLP 40.19%. There was a decrease in radiation dose from 100 kVp to 80 kVp for CTDI 52% and DLP 49.88%.Conclusion: The tube voltage setting on head CT scan examination of the base skull area can be applied with 100 kVp because this is evidenced by the same total score at 100 kVp and 120 kVp, which is 100% is very clear, while at 80 kVp tube voltage only 71% is very clear. And the radiation dose at 100 kVp is lower than 120 kVp.

Abstract

Backgroud: blurring artifact is an issue in axial cervical MRI using T2 Turbo Spin Echo (TSE) weighted Cartesian. T2W TSE BLADE is potential to substitute its shortcomings. This study aims to analyze the image quality and artifacts between T2W TSE Cartesian and T2W TSE BLADE on axial cervical MRI examination and to determine the better sequence in producing image quality.Methods: this is a quantitative research with descriptive approach. 7 volunteers were scanned for cervical axial examination with T2W TSE, T2W TSE Cartesian and T2W TSE Blade. Images were processed in MathlabTM. SNR of intervertebral disc, spinal cord and CSF were measured using ROI. Image resolution were find out from pixel spacing in DICOM info. Blurring artifact were analyzed by comparing the signal of blurred area to the background noise. Data were analyzed using descriptive statistics.Results: SNR of T2W TSE Cartesian and T2W TSE BLADE were 22,144 and 17,532 (intervertebral disc), 20,952 and 16,786 (spinal cord), and 16,717 and 12,883 (CSF) respectively. Image resolution (mean) were 0,391 pixel/mm (T2W TSE Cartesian) and 0,625 (T2W TSE BLADE). Blurring artifact were 8,161 (T2W TSE Cartesian) and 6,826 (T2W TSE Blade).Conclusion: T2W TSE Cartesian was superior in pixel intensity and SNR, while the blade technique was superior in terms of spatial resolution and artifacts reduction. Thus, it is recommended to be applied in clinical field if the SNR or image detail is the priority.
