Abstract

Hepatitis is inflammation of the liver due to viral or alcohol infection. Hepatitis can cause death and the case always increases every year both in Indonesia and the world. The aim of this study is to describe and evaluate the management of examination such as patient preparation procedure, tool preparation, patient position, transducer placement, transducer used, and ultrasound image of hepatitis. This research was conducted by qualitative descriptive method. The population is all patients who perform liver ultrasound examination at RSUD Cengkareng Jakarta. The samples used were patients who performed liver ultrasound examination with clinical hepatitis. The number of samples used is 2 patients. After being analyzed and observed, ultrasonography is an accurate and accurate examination of the hepatitis case. Additional scripting techniques are sometimes required in certain cases to make the results more optimal. Based on this research, it can be expected that ultrasound modalities can be used as an appropriate supporting tool in establishing clinical hepatitis with accurate, fast, cheap and safe results.

Abstract

CT number is one of the indicators in determining the diagnosis of disease, so it is necessary to ensure the level of accuracy. The aim is to determine the parameters of kilovoltage and tube current to the CT value. Descriptive quantitative analytic research method with previously tested linearity and the suitability of the CT number. Furthermore, the variation of kilovoltage: 80kVp, 100kVp, 140kVp and the tube current value is 192mAs. After that, the tube current variation was continued: 80mAs, 100mAs, 140mAs and the voltage value was 120kVp. Phantom image results were analyzed using radiant viewer software with a region of interest (ROI) size of 5mm. Then analyze the correlation coefficient to determine the degree of relationship between the kilovoltage and milliampere-second parameters to the CT number. The results of the linearity test and the suitability of the CT number value were within the tolerance limit. For variations in kilovoltage to CT number , the correlation coefficient values ​​are water R2=0.09, fat R2=1, soft tissue R2=0.9, bone R2=0.7. As for the milliampere-second variation of the CT number , the correlation coefficient values ​​are: water R2=0.7, fat R2=0.8 , soft tissue R2=1, bone R2=0.7.

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
