Abstract

Background: Multislice Computed Tomography (MSCT) is utilized for the measurement of bleeding volume in hemorrhagic stroke patients. This is very necessary to determine the right medical action. Errors in measurement can lead to suboptimal medical measures taken. Objective: to analyze the measurement and calculation of fluid volume by automatic and manual methods on the volume of fluid contained in the phantom on MSCT. Methods: The type of research is quantitative experimental with the sample used is a phantom made of polyethylene (Dacron) filled with irregular milk liquid as much as 10 volume variations. The research instruments used were worksheets and interview sheets. Data processing and analysis are descriptive by getting the average value. Results: Measurement and calculation of irregular volume of 10 ml, 20 ml, 30 ml, 40 ml, 50 ml, 60 ml, 70 ml, 80 ml, 90 ml, and 100 were done automatically on the CT scan plane and manually using the formula ½ A x B x C. The automatic method had an average volume difference of 1.39% and the manual method had an average volume difference of 6.88%. The automatic method has a small volume difference. Conclusion: the measurement and calculation of volume with the automatic method has a better accuracy value than the manual method. The results of these measurements and calculations are highly dependent on the accuracy of precise segmentation techniques on the object.

Abstract

Type A aortic dissection is a longitudinal tear separating the intima layer from the aortic media and is often not clearly visible due to cardiac motion which can reduce image quality and misrepresent the lumen so that the flowing blood causes several problems such as the aortic root and ascending aorta. CT angiography with ECG gating was chosen to reduce the images of cardiac movement. The purpose is to evaluate the examination procedure and anatomical description of the CT Angiography examination with Gating ECG. The research method is descriptive qualitative research with a case study approach with samples selected based on the examination diagnosis with type A aortic dissection. Observation, documentation, interviews did data collection. Data analysis is described in a descriptive narrative, and a conclusion is drawn. The result of the study is that CT angiography examination with ECG gating provides accurate information that the coronary arteries originate from the true lumen. In this phase, there are no lines that show a significant picture of heart movement disorders so that the coronary arteries can be assessed properly. The anatomical features of MIP, CPR, and VRT visualize the aortic root region until the coronary arteries are displayed more informatively than heart movement disorders. The conclusion is that CTA examination with ECG gating can show the aortic root in cases of type A dissection located at the root or ascending aorta and minimize heart movement interference with MIP, CPR and VRT.

Abstract

Background: Routine pelvic radiograph examination commonly performed in diagnostic radiology services is a pelvic examination of anteroposterior projection (AP). This results in direct exposure to ionizing radiation to the internal organs in the lower abdomen, especially the reproductive organs. Purpose: Optimizing the dosage of AP projection pelvic radiographs. Method: Research is conducted quantitatively and used experimental approach with an analysis of 15% mAs reduction from the standard mAs value on AP projection pelvic examination on radiation dose and image quality using anthropomorphic phantoms. The radiation dose analysis uses the exposure index indicator. In contrast, the image quality uses the Visual Grading Analysis method, then it was continued with the Kappa Cohens test to determine the level of agreement between 2 respondents. Result: The exposure factor with the mAs value reduced by 15% from the standard exposure factor on the AP projection pelvic radiography affected the decrease in the value exposure index. The EI value generated from the optimization exposure factor shows a decrease to 300 EI, which means the dose produced is only half of the standard exposure factor dose but still produces an acceptable image, as evidenced by the VGA score. As an assessment of image quality. In this study, there was no significant difference with range VGA scores 1,7. Besides that, the test had the Kappa Cohens level of agreement with a value of 0.5-0.8. Conclusion: All images resulting from the 15% mAs value reduction variation can be used as a diagnostic assessment.

Abstract

Radiology is a vital component of healthcare services in hospitals, aimed at assisting diagnoses through radiographic imaging using X-rays. To ensure optimal image quality, a quality assurance program is implemented. One of the objectives of this program is to minimize the repetition of radiological examinations. Therefore, a reject analysis of radiographic images is conducted to identify the causes and reasons for repeated imaging. This research aims to analyze the factors contributing to repeated computed radiography (CR) images to improve the quality of radiology health services. It is a quantitative descriptive study conducted through observation to determine the percentage of image repetitions and identify the causes. The data was analyzed using the repeat rate formula to calculate the repetition percentage systematically. The study took place from February to April 2024, with a total of 8,197 CR images, of which 410 were repeated. Results: The quality of radiology services is categorized as good, based on a monthly image repetition rate of 1.75%, which is within the acceptable limit of ≤2% as per the Indonesian Ministry of Health Regulation No. 129/Menkes/SK/II/2008 on minimum hospital service standards.

Abstract

Background: Hepatocellular Carcinoma (HCC) is the third leading cause of death in the world. One important aspect of lesion measurement in predicting HCC grading on Magnetic Resonance images is the ADC value obtained by performing Region of Interest can be a variation in shape size of Freehand, Circle, or Point voxel.Methods: Analytical quantitative research by comparing three shapes sizes ROI on the value of ADC in cases of HCC. Data was collected at the Radiology Installation of hospitals in Jakarta from 50 patients who underwent liver MRI with DWI-ADC Map images between January and October 2023. Analysis of data using Friedman test statistical test followed by Dunnet post hoc test.Results: ADC value for Freehand ROI was 1.33x10-3 mm2/s, Circle ROI was 1.31x10-3 mm2/s and Point Voxel ROI was 1.23x10-3 mm2/s. The statistic p0.05 means that there is a significant difference in ADC values between Point Voxel and Freehand and Circle ROI.Conclusions: ROI with different size shapes (Freehand, Circle, Point Voxel) affects ADC value. Circle ROI is recommended to evaluate HCC because the placement of the ROI can avoid inhomogeneous areas when measuring the ADC value on an MRI of the Liver with Hepatocellular Carcinoma.

Abstract

Background: Magnetic Resonance Imaging (MRI) is a non-invasive imaging modality essential for evaluating complex anatomical structures such as the knee joint. MRI allows multiplanar imaging with high soft tissue contrast resolution. In knee imaging, the sagittal plane is particularly effective in assessing pathologies and visualizing structures like cartilage, menisci, bones, and ligaments (ACL and PCL). Proton Density Weighted (PDW) sequences combined with Spectral Adiabatic Inversion Recovery (SPAIR) fat suppression are commonly used to enhance soft tissue visualization. The image quality in SPAIR sequences is significantly influenced by the Time Inversion (TI) parameter. This study aimed to analyze the impact of varying TI values on the image quality of sagittal PDW SPAIR MRI of the knee joint, focusing on anatomical detail and contrast resolution.Methods: This research used a quantitative analytical method with an experimental approach. The study was conducted at the Radiology Department of Pertamina Central Hospital from March to April 2025. Ten knee MRI examinations were selected as samples. Image quality was assessed by three radiologists using a structured scoring questionnaire. The data were analyzed using non-parametric statistical tests, including Friedman and Wilcoxon Signed-Rank tests.Results: The Friedman test revealed statistically significant differences in anatomical detail (χ²(2) = 15.000, p = 0.001) and contrast resolution (χ²(2) = 17.882, p = 0.000) across the three TI values (100 ms, 160 ms, and 200 ms). Post-hoc Wilcoxon analysis showed that both TI 160 ms and 200 ms provided significantly higher image quality than 100 ms (p 0.017) in both parameters. However, no significant differences were found between TI 160 ms and 200 ms (p = 0.506 for anatomical detail, p = 0.273 for contrast resolution). Among the values tested, TI 160 ms demonstrated consistent and optimal scores for both image clarity and contrast.Conclusions: A TI value of 160 ms in the PDW SPAIR sequence is recommended as the optimal parameter for producing superior sagittal MRI images of the knee joint, particularly in terms of anatomical clarity and contrast resolution.

Abstract

The set-up aims to find out the value of the shift that occurs while the patient is undergoing the irradiation process on the X-axis (right-left), Y-axis (caudal-cranial), and Z-axis (anterior-posterior). The procedure for collecting research data is by making direct observations and being involved in measuring set-up shifts. The data used amounted to 20 nasopharyngeal cancer patients. Set-up shift measurement data were taken sequentially from fractions 1-33 for each patient using 4 and 9 points locks masks. Analysis of statistical test data using SPSS version 25, to determine the effect of using 4 and 9 points locks masks on shifts in nasopharyngeal cancer irradiation set-up patients with fraction group: Group 1 (fraction 1), Group 2 (Fraction 2 – 15), Group 3 (16-33)  using the Wilcoxon test because the normality test results were not fulfilled. If the p-value ≤ 0.05, there is an effect of using 4 and 9 points locks mask on shifts, while for p-value ≥ 0.05, there is no effect of using 4 and 9 points locks mask on set-up shifts in nasopharyngeal cancer irradiation set-up. The results of the shift in the set-up of 4 and 9 points lock irradiation vertically in the lateral, longitudinal, and vertical directions tend to be positive (left, caudal, posterior). There was no effect of all fraction groups using 4 and 9 points locks on the shift in nasopharyngeal cancer irradiation set-up p-value> 0.05.
