Abstract

The use of water as a contrast medium requires large amounts of water to fill the lumen of the Urinary Tractus and more water is reabsorbed by the body than is secreted into urine. Steeping Black tea contains Caffeine which is able to increase blood flow in the kidneys thus inhibiting the process of absorption of Na, Ca and Mg causing stimulation of the kidneys to increase the amount of urine production. The purpose of this study is to prove that drinking black tea can increase urine production as a negative contrast medium to see differences in the distension and density of the Urinary Tract on CT Urography examination. This type of research uses True Experimental with Pretest-Posttest Control Group Design research design. Patients selected by Simple Random Sampling. Analysis: Paired t test and Independent t test. The results of the study of the use of 600 ml steeping Black Tea as a negative contrast medium on CT Urography examination did not show the difference in mean difference between the left renal Pelvis p value 0.956, Left UVJ 0.640, Right UVJ 0.935 while on the right renal Pelvis p value 0.001 showed differences in mean difference between the left renal Pelvis p value 0.956, Left UVJ 0.640, Right UVJ 0.935 while on the right renal Pelvis p value 0.001 intervention and control group. Hasil pengukuran p value  densitas Vesika urinaria sebesar 0,678. Conclusion: Black tea can be used as a negative contrast medium on CT Urographic examination but when compared with mineral water it does not show a significant difference.

Abstract

The quality of radiographic images is highly dependent on exposure factors including tube voltage (kV), tube current and exposure time (mAs). The Contrast to Noise Ratio value can transmit image quality, a higher CNR indicates a good image with less interference (noise). The study aims to determine the effect of exposure factor variations on the CNR value and which exposure factors that produce optimal CNR in AP cranium projections. This study uses a quantitative method, an experimental study at the Radiology Installation of the Siti Rahmah Padang Islamic Hospital in September 2024. Data were obtained from cranium phantom images with variations in tube voltage (kV) 68, 74, and 78, and current and exposure time (mAs) 10, 12, and 14. The images were analyzed using the Radiant DICOM Viewer application with the ROI technique to calculate the CNR value in the anatomical area, namely the frontal, crista gali, mandible, both orbits and the background. The ROI results were analyzed using multiple linear regression tests. The results showed that the variation of exposure factors had a significant effect on the CNR value of 94.7%. The optimal exposure factor, at 68 kV and 14 mAs, with the highest CNR of 44.598. The lowest CNR value at an exposure factor of 78 kV and 10 mAs was 22.063. These results can be used as a reference in determining the optimal exposure factor in AP cranium examination

Abstract

Computed Tomography (CT) is an essential imaging modality for evaluating head trauma due to its ability to provide detailed cross-sectional images. Image quality, particularly the Contrast to Noise Ratio (CNR), plays an important role in diagnostic accuracy. This study aimed to determine the effect of reconstruction increment variations on CNR values in head trauma CT examinations and to identify the increment that provides the most optimal image quality. This research was a quantitative experimental study conducted at the Radiology Unit of RSUD Prof. Dr. M.A. Hanafiah, SM Batusangkar, in February 2025. The population consisted of all patients who underwent CT brain examinations with clinical head trauma during the study period, totaling 12 patients, of whom five patients were selected as samples using purposive sampling. Secondary image data were reconstructed using two increment variations, 0.7 mm and 1 mm, with identical scanning parameters. CNR values were calculated using Radiant Viewer by measuring regions of interest (ROI), and the data were analyzed using the Shapiro–Wilk normality test followed by the Independent Samples T-Test. The results showed that the mean CNR value for the 0.7 mm increment was 304.52, which was higher than the 1 mm increment with a mean CNR of 288.51. However, statistical analysis demonstrated no significant difference between the two increment variations (p = 0.155; p > 0.05). In conclusion, both reconstruction increments produce comparable image quality in head trauma CT examinations. Nevertheless, the 0.7 mm increment provides higher CNR values and may be considered more optimal for improving image clarity

Abstract

The tongue and lip mucosa, as tissues with high cell proliferation rates, are highly susceptible to injury caused by ionizing radiation. This study aimed to evaluate histological changes in the tongue and lip mucosa of rats after exposure to ionizing radiation at various doses. Nine rats were used, each consisting of three rats, divided into a negative control group (K) and three treatment groups receiving radiation doses of 13 Gy (30 seconds of radiation), 15 Gy (66 seconds of radiation), and 17 Gy (110 seconds of radiation). Samples of tongue and lip mucosa tissue were harvested after 7 days and processed for histological examination using Hematoxylin and Eosin (HE) staining at 100x objective magnification. The results of this preliminary study showed that radiation at 13 Gy caused epithelial erosion, loss of filiform papillae, subepithelial bullae formation, and acute inflammatory cell infiltration on the tongue. At 15 Gy, more extensive ulceration with subepithelial edema was observed. At 17 Gy, total epithelial loss with massive subepithelial edema and vascular dilatation occurs. This preliminary study concludes that the tongue mucosa exhibits greater radiation sensitivity than the lip mucosa, with a dose-dependent progression of damage ranging from erosion to total epithelial loss.
