Abstract

Background: Kidney stones (nephrolithiasis) are solid masses formed from urine precipitated crystals. The formation of stones is caused by increased calcium, oxalate and uric acid content in the body, scans to view kidney stones (nephrolithiasis) can be performed with or without contrast. Non-contrast CT urography is the imaging modality of choice for the initial evaluation of patients with suspected urolithiasis, as it has a sensitivity of up to 98% and specificity of 96-98%. Components that affect image quality in CT scans are spatial resolution, contrast resolution, and noise. One of the important parameters in image quality is the selection of slice thickness. Spatial resolution is the ability to show objects or organs with a high level of contrast. Noise is the standard deviation percentage of the sum of pixel values obtained from the waterbath image. Methods; This type of research is quantitative research with an experimental approach to analyze the effect of slice thickness variations on image quality using variations of 2 mm, 3 mm, 4 mm, 5 mm, and 6 m. The data were collected in August 2023 with 10 samples. Data were collected in August 2023 with 10 samples. Researchers took urographic CT scan examination data with a diagnosis of nephrolithiasis. Results and Conclusion: With the results of the research conducted, it can be concluded that in the overall Friedman test results there is an effect of using slice thickness variations on image quality in urographic CT Scan examinations with nephrolithiasis diagnoses. using slice thickness variations. Based on the results of this study, the researcher can recommend on CT Scan urography with nephrolithiasis diagnosis using 4 mm slice thickness to get good and optimal image quality results.

Abstract

Background: Thyroid tumors are abnormal growths of the thyroid gland, which can be benign or malignant tumors such as papillary, follicular, medullary or anaplastic types (Aldino, 2018). CT scan of the neck according to (Lee at al, 2016) The contrast media used consists of 80 ml of non-ionic contrast media followed by 20 ml of saline given through the antecubital vein using a power injector and a 20 gauge intravenous catheter at a speed of 2.5- 3.0 ml/sec. According to (Yang et al., 2016) 80-100 ml of 300 mg/L omnipaque contrast media is injected through the cubital vein at a rate of 2.7-3.0 mL/s. And according to (Deng et al., 2019), 80 ml of iopromide (300 mgl/mL) contrast media is injected intravenously at a rate of 3 ml/sec. The aim of this research is to determine the procedure for a CT scan of the neck with contrast in cases of thyroid tumors in the radiology installation at the NTB Provincial Regional Hospital. Method: The type of research carried out is qualitative research with a case study approach. Data were collected by observation, interviews with one radiologist and three radiographers and documentation. Data collection was carried out from June to July 2023. Data analysis was carried out using an interactive model system. Results: This study shows that the contrast media used in CT scans of the neck uses 50 ml contrast media on the grounds that 50 ml contrast media can confirm the diagnosis because in the case of tumors in the thyroid you only want to see whether there is enhancement of the tumor. And the contrast media injection is carried out manually by a radiology nurse on the grounds that it is sufficient to confirm the diagnosis if it is carried out with proper control so that the examination is simpler and the processing time is faster. Conclusion: There is a difference in the CT scan of the neck between theory and the NTB provincial hospital where in theory Lee et al (2016) explains that 80 ml of contrast media is used and an injector is used at a speed of 2.5-3.0 ml/s while the provincial hospital NTB uses 50 ml contrast media and is injected manually by a radiology nurse on the grounds that this can confirm the diagnosis.

Abstract

Comparison Of Metabolic Value On MR-Spectroscopy With and Without Contrast Media at Persahabatan Hospital, East Jakarta. Magnetic Resonance Spectroscopy is a non-invasive technique that can be used to measure the metabolism of several biochemical components in body tissue, especially the brain. Based on observations made by the author at Persahabatan Hospital, the spectroscopy technique used at Persahabatan Hospital is a multi-voxle technique, with sequences selction namely s2D_PRESS_144, where the spectroscopy images are taken after administering contrast and prevalence for tumor cases in the Radiology Installation at Persahabatan Hospital, with 5 data from the month May-August 2023. To determine the validity of this opinion, the authors performed pre and post- contrast MR-Spectroscopy on patients with contrast and compared the results with patients without contrast. In this study the author used a quantitative analysis type of research with an experimental approach aimed at whether the administration of contrast material affects the results of MR-Spectroscopy in patients with brain tumor cases. Where the research data comes from primary data in the Radiology installation at Persahabatan Hospital from May - August 2023 using 5 patient data. Results: Based on an observational study carried out on primary data from 5 patients, there were differences in metabolic values with and without contrast media in brain tumor cases. And MR-Spectroscopy examination without contrast is better to use than with contrast, although from the overall data it turns out there are some data that say post- contrast is higher.
