Abstract

Background: Stroke is a diseas that has a high mortality rate as the third most common disease that causes death in the world. To diagnose the location and type stroke, a neuro imaging examination is need, which is by examining the CT Scan of the head. The purpose of this study was to determine differences in diagnostic information on CT scan of the head in cases of ischemic stroke with a choice combination of 3 mm slice thickness with 1.5 mm interval reconstruction and 2 mm slice thickness with 1 mm interval reconstruction, and to find out which combination is the most optimal in producing diagnostic information in cases of ischemic stroke. Methods: This type of research is quantitative research with experimental approach. The study was conducted at Telogorejo Hospital Semarang. The sampel in this study were 10 patients with expertise results of ischemic stroke. The resultan data was 10 head scan radiographs with ischemic stroke and each radiograph is reformatted with combination of 3 mm slice thickness with 1.5 interval reconstruction and 2 mm slice thickness with 1 mm interval reconstruction. Assesment of diagnostic information data was done by 3 respondents. before data analysis, first kappa test was done to three respondents and then tested wilcoxon. Result :The result of this research is the difference of diagnostic information between combination of 3 mm slice thickness with 1.5 mm interval reconstruction and 2 mm slice thickness with 1 mm interval reconstruction. A combination of 2 mm slice thickness with 1 mm interval reconstruction with mean rank 21.00 is the most optimal combination for head scan with ischemic stroke cases

Abstract

Background: Cardiac angiography CT examination is a non-invasive measure to evaluate coronary blood vessels. Multislice CT with a high level of sensitivity and specificity is required to be able to reconstruct data from a constantly moving heart, resulting in diagnostic and informative image quality. Heart movement or heart rate plays a role in the occurrence of motion artifacts so that a stable heart rate is required at the time of data acquisition. The purpose of this paper is to see the role of the heart rate in cardiac CT Angiography examination and to determine the value of the heart rate to obtain the best image quality. Methods: The research method uses a literature study approach by describing the article. Article searches use Science Direct, Radiopedia, American Journal Radiography, and Google Search to find articles that match inclusion and exclusion criteria so that 4 articles are obtained and then they are reviewed. Results:: The study results show that the heart rate plays a very important role in producing image quality from CT examination. Cardiac angiography, a stable heart rate will minimize the occurrence of artifacts, which is one of the points in the image quality parameter. A stable heart rate to get the best image quality is at ≤60 BPM when data acquisition with low heart rate variability Conclusion: .Nilai heart rate untuk mendapatkan kualitas citra yang informatif dan diagnostik pada nilai heart rate 60 bpm, sehingga kualitas citra akan baik.

Abstract

Background: The protocol for MSCT Thorax examination is axial/coronal/sagittal. The slice thickness parameter has an important role in examining MSCT Thorax in breast cancer cases using contrast media. The thinner the slice thickness, the better the detailed image obtained. The aim of this study is to explain the MSCT Thorax examination procedure in breast cancer cases using positive contrast media, the role of slice thickness in diagnosis and to find out diagnostic information on the MSCT Thorax examination in cancer cases breast. Methods: This type of research is qualitative with a literature study approach. The data were obtained by identifying the problem then looking for keywords, namely MSCT Thorax, Slice thickness, breast cancer. Literature reviews are carried out through journal search engine searches, such as: Google Scholar, American Journal Rontgenology (AJR), Pubmed, Proquest. The collected journals are reduced based on inclusion criteria so that 3 relevant journals are obtained then analyzed descriptively so that they can answer the objectives to be drawn conclusions. Results: The results of a literature study show that the MSCT Thorax examination procedure in cases of breast cancer using contrast media is fasting 6 hours before the examination, laboratory checks (urea cratinin within normal limits), releasing all metals in the body, CT scan plane, fixation tools, blankets. , contrast media, injector set. Conclusion: Contrast media dosage 1-2 ml / kg body weight, flow rate 2-4 ml / s, concentration 300-350 mgl / ml, patient position supine feet first, upper limit of lung Apex and lower limit of diaphragm (depending on needs), axial cut, coronal, sagittal, the parameters used were kV, mAs, slice thickness, matrix, WW, WL. A thin slice thickness will provide more accurate diagnostic information and a clear picture of metastases and small lesions can be seen.

Abstract

ABSTRACT Background : Multi Slice Computed Tomography is a diagnostic imaging method that can display cross section anatomy in the axial, sagital, and coronal areas. 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.
