Abstract

ABSTRACT Background :The lopographic examination according to Lampignano and Kendrick (2018) uses barium sulfate contrast media which is inserted through the stoma, using plain photos, AP/PA, Lateral, Oblique, post evacuation. Installation of Radiology Hospital Prof. Dr. Margono Soekarjo Purwokerto using a non-ionic water soluble contrast media mixed with NaCl, inserted into the proximal stoma and anus with plain photos, AP, Lateral. The purpose of the study was to determine the lopographic examination procedure, the reasons for using water soluble contrast media, to find out anatomical information from the AP and Lateral. Methods :This research used qualitative approach with a case study. Data collection were used observation, interviews, documentation. Research respondents were patients, radiographers, radiologist, and dispatching doctors. Data analysis with interactive analysis model. Result : Showed that the lopographic examination was aimed at evaluating the colon after colostomy and chemotherapy. Patients undergo special preparation. The water soluble contrast medium was mixed with NaCl in a ratio of 1: 4 because it was safer than barium sulfate. The reason for insertion of contrast media through the proximal stoma and anus is the absence of a stoma to the distal colon. Anatomical information from the plain photo is the distribution of air in the colon, the AP projection looks contrast to fill the ascending colon, transverse colon, descending colon and superpositioned sigmoid colon. Laterally, the sigmoid colon and rectum are seen. Diagnostic information was not found in colonic carcinoma residif cells.

MSCT Stonography imaging both visualizes the anatomy of the urinary tract and stone pathology supported by the presence of ureter tracking techniques and without using contrast media. On this method, the appropriate window width will produce an optimal anatomical picture. The Study aims to determine the effect of window width on anatomical image information on MSCT Stonography. Methods : Type of research is quantitative experimental approach, conducted in January-February 2020 in Hasan Sadikin Bandung hospital, Bandung. Research with variations in window width 300 HU, 350 HU, 400 HU, 450 HU, and 500 HU on MSCT stonography og 10 patients. Criteria’s patients is patients with clinical kidney stones, willing to be a research sample. Result imagery rated two respondents, include parenchymal kidney, pelvic calices kidney, ureters, vesica urinary, and stones kidney. Then do Kappa test continued testing Friedman to know the highest mean rank and the influence og the window width oh the image og MSCT stonography. Results : Based on the result of the Friedman statistical test overall anatomy obtained significance value (p-value) = 0.000 < 0.05 means that there is an influence of window width value, the contrast resolution will increase and the better the firm boundary, but the resulting image will be more radioluscent. Based on Friedman’s mean rank test result obtained the highest mean rank of 3,54 in a variation of window width 300. The most optical window displays anatomy information using window width 300. Conclussion : There are difference in anatomical image information of MSCT stonography among 5 variation window width on examination MSCT stonography. Window width 300 HU is better at anatomy information on MSCT stonography to show better contrast, crisp sharpness, no blur image.

Abstract

Background : The split bolus technique in CT Scan urography is an intravenous contrast media insertion technique by combining two phases, namely the nephrography phase and the excretory phase in one scan acquisition. In general, the CT Scan urography examination uses 3 phases, non-contrast phase, the nephrographic phase, and the excretory phase. In the role of the split bolus technique, the combination of two phases, namely the nephrographic and excretory phases. The purpose of this study was to explain the split bolus technique and the role of the split bolus technique on anatomical information in CT Scan urography. Methods : This type of descriptive research using a literature review approach. The keywords used are "Split-bolus", "CT Scan Urography". Articles were obtained based on inclusion and exclusion criteria and 7 relevant scientific articles were obtained and were used as literature sources. Data processing through article extraction. Result : The split bolus technique in CT Scan urography examination is a technique of intravenous contrast media that combines two nephrographic and excretory phases in one image acquisition with an average flow rate of 1.5 ml - 3 ml / s. This technique uses a non-ionic iodine contrast medium with a volume of 90 ml - 135 ml and a concentration of 300 mg/ml-370 mg/ml. The role of the split bolus technique on radiation dose and anatomical image information is due to the merging of the two phases in one scan which addresses the anatomy of the urinary system. In addition, the split bolus technique when combined with several reconstructions is able to increase contrast resolution and increase organ enhancement. In this technique, it is better to use the addition of a reconstruction algorithm such as 3D MIP, so that the anatomical image information obtained is more optimal.

Abstract

ABSTRAK Background: The urinary tract (urinary system) consists of the two kidneys and ureters, the urinary bladder, and the ureters. There are several ways to examine abnormalities in the urinary tract radiologically. including the current CT scan, CT Scan (MSCT) is one of the modalities to evaluate and diagnose urinary tract disorders. MSCT of the urinary tract without using positive contrast media is able to identify images of the urinary tract in cases of urolithiasis. iDose and Interative Model Reconstruction (IMR) are the second generation of IR algorithms from the previous generation, namely iDose. This technology can also lower the dose to the patient and also improve the quality of the resulting image. Method: This type of research is an experiment with an observational approach with comparisons. This type of research is an experiment with data obtained from a comparison of noise values and the quality of anatomical images from tracking images with iDose and IMR variations. And an assessment was carried out by 3 radiologists. Place of data collection in radiology RSUD RAA Soewondo Pati. Time for data collection From April to November 2022. in assessing anatomical images using statistical tests. Data analysis was carried out using the Wilcoxon statistical test method because the data were ordinal with paired groups. The Wilcoxon statistical test was used to test the hypothesis and see the level of difference in anatomical image information. The level of significance (level of significance) is 95% or α> 0.05 and is done by assessing the p-value. For a significant level of assessment p <0.05 then Ho is rejected and p> 0.05 then Ho is accepted. Results: Friedman test on each anatomical part of the urinary tract system on Non-Contrast Urography MSCT images with Tracking Techniques with iDose 1-6 and IMR 1-3 variations, there are differences in anatomical image information with a p value of .000 (p <0.05). In the anatomy of the renal parenchyma, the highest mean rank is iDose 3 with a value of 8.15. In pelvic anatomy and kidney calices, the highest mean rank is at iDose 6 with a value of 8.05. In ureteral anatomy, the highest mean rank is iDose 3 with a value of 8.05. In the anatomy of the perirenal space, the highest mean rank is iDose 3 with a value of 8.20. Based on the results of the mean rank Friedman test to find out the optimal I Dose and IMR values, it was obtained iDose 1 with a mean rank value of 4.65, iDose 2 with a mean rank value of 4.95, iDose 3 with a mean rank value of 8.3, iDose 4 with a mean rank value of mean rank 6.4, iDose 5 with a mean rank value of 6.55, iDose 6 with a mean rank value of 7.75, IMR 1 with a mean rank value of 1.65, IMR 2 with a mean rank value of 2.05, and IMR 3 with a mean value rating 2.7. Conclusion: Changes in the values of iDose and IMR variations affect the anatomical image information of Non-Contrast MSCT Urography with Tracking Techniques, this is based on the results of the mean rank Friedman test performed on each anatomy of the renal parenchyma, pelvic calices, ureters and perirenal space which shows a difference. Based on the results of Friedman's mean rank test conducted on the entire anatomy of the renal parenchyma, ureters, and perirenal space, it showed that the optimal iDose and IMR variation values were iDose 3 with a mean rank value of 8.3.
