Abstract

Background: Settings for Window Width and Window Levels used in CT Scan Thorax tumor cases vary. On Seimens 128 Slice plane there are standard settings for lung window thorax is with Window Width 2200 HU and Window Level -200 HU while according to window width theory is 1000- 2000 HU value range and window level -200--800 HU. The purpose of this research is to know the difference of variation setting Window Width and Window Level on Lung Window and Window Width and Window Level optimum in producing anatomical information CT scan thoraks in case of lung tumor.Method: The type of research conducted in the writing of this final task is quantitative research using experimental approach. Data were collected on 5 patients suspected of lung tumor, then variation of setting window width and window level. The result of variation of window width and window level setting was then evaluated by 2 observers to obtain anatomical information of CT Scan Thorax in lung tumor case then analyzed by using Friedman Test different from spss version 16.0.Result: The result of the research resulted the difference of Window Width and Window Level was assessed from p value α (0.05). the value of significance p value 0.001 which means there is a difference. Highest mean mean value with value 8.25 in window width 1800 HU and window level -200 HU. The use of the most optimal setting variation is the Window Width 1800 HU and Window Level -200 HU because it can provide anatomical image information of CT Scan Thoraks optimal lung tumor cases where the anatomy of the pulmonary, broncus, trachea, aortic mass, pulmonary and chest lung par clearly visible and bordered on axial pieces.

Abstract

Backgroud: MRCP is a non-invasive imaging examination, which is used for the evaluation of biliary tract, pancreatic duct, and gallbladder. Pulse sequences which can be used to visualize organs in MRCP on T2 weighting is using a fast pulse sequences such as sequences TSE or Haste. The purpose of this research was to knowing the difference image information between T2 axial TSE with Haste and where better to use between the two sequences on axial T2 MRCP examination.Methods: This type of research is experimental observational approach, it has been carried out in the best MRI 1.5 Tesla at RSU Haji Surabaya. Sample used were 5 patients. Each patient performed two pieces of axial T2 sequences in which the TSE and Haste. Furthermore, the image submitted to the three doctors radiologist to fill out a questionnaire that has been provided to assess the image consisting of the liver, gallbladder, common bile duct (CBD), pancreas, intrahepatic duct and an assessment of the artifacts.Results: The results of analytical assessment Wilcoxon test, for the entire anatomy with ρ value of 0.002 which means that ρ 0.05, and the artifacts show the ρ value of 0.006, which means ρ 0.05. This proves that there are differences in image information between T2 axial TSE with T2 axial Haste the MRCP examination. At each of anatomy, liver has ρ value of 0,071 (ρ 0.05), gallbladder has ρ value of 0.317 (ρ 0.05), CBD has ρ value of 0.003 (ρ 0.05), pancreas has ρ value of  0.014 (ρ 0.05) and intrahepatic duct has ρ value of 0.004  (ρ 0.05). Based on the mean rank statistical test results show sequence Haste better in generating image information on the whole anatomy, but in each of anatomy based on the mean rank of gallbladder both sequences are equally good in showing gallbladder, whereas to display the liver, CBD, pancreas, and intrahepatic duct, the results showed T2 Haste mean rank better, it is because it has the characteristics of high Haste T2 signal intensity and better in reducing motion artifacts.Conclusion: Wilcoxon test analysis results expressed Ha accepted, meaning that there is a difference between the image information pieces axial T2 TSE with Haste the MRCP examination. The mean rank shows Haste superior to TSE, this is because the artifacts on TSE and therefore contributes to the respondent's assessment, other than that Haste has a high signal intensity so that it can show more clearly ducts.

Abstract

Background: Examination of thyroid scintigraphy or thyroid gland scintigraphy is a nuclear medicine examination using radioactive substances or radiopharmaceuticals that are inserted into the body through intravenous injections which aim to obtain functional morphological imaging of the thyroid and to assess the ability of the thyroid gland to capture radioactive substances or radiopharma-ceuticals.Methods: This imaging prosedure using Tc-99m (Technisium-99m) radiopharmaceuticals as much as 2-5 mCi. To get maximum results, patients are asked to stop taking drugs that can interfere with iodine accumulation in the thyroid gland.Results: Imaging was carried out 10-15 minutes after injection of the radiopharmaceutical. Marked with the thyroid cartigalo, jugulum and surgical sutures. The scanning process lasts for 5-10 minutes.Conclusions: The imaging results of hot nodules are generally identical to autonomic thyroid nodules, about 10-30% of cold nodules are found in the thyroid malignancy process while the rest are thyroid cysts.
