Abstract

A contrast thorax CT scan is a CT scan procedure in the chest area (thorax) that uses a contrast agent to improve visualization of organs and structures in the chest. Lung tumors are the growth of abnormal lumps in lung tissue which can be benign or malignant. Awareness of the potential and increasing radiation dose in all CT scan examinations encourages radiographers to want and be able to minimize radiation exposure as the main goal in radiological examinations and also strive for radiation protection during examinations. CT scan radiation dose accounts for 70% of the total dose received from medical imaging. High or low doses of radiation received can increase the risk of cancer. The large dose of radiation received by a patient during a CT scan, therefore regulations are needed that will guarantee monitoring of the radiation dose received by the patient to ensure that the dose received is commensurate with medical purposes. The radiation dose to the patient needs to be optimized by applying the Diagnostic Reference Level (DRL) to optimize medical exposure protection for the patient. Dosage evaluation in clinical contrast chest CT scan examinations for lung tumors and the application of DRL in these examinations have never been carried out at RS X Jakarta. Objective: This study aims to determine the DRL value in clinical contrast thorax CT scan examination of lung tumors at RS CTDIvol and DLP values from clinical contrast Thorax CT Scan examination of lung tumors. The DRL value is calculated at Quartile 3 (75 percentile) using the descriptive frequency test and Wilcoxon test in the SPSS application, then compared with the latest IDRL value. Results: Quartile 3 value (75 percentile) from CTDIvol and DLP CT scan chest contrast clinical lung tumors, namely The CTDIvol value was 12.55 mGy and the DLP was 439 mGy.cm. Conclusion: The DRL value in the clinical contrast thorax CT scan for lung tumors at Hospital X Jakarta. is still below the recommended standard, which shows that the radiation output dose in this examination practice is within normal limits and is classified as safe

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.
