Abstract

Background: World consumption of hydrogels from synthetic polymers is more than one million tons per year (El Mohdi, 2009). This can cause serious environmental damage problems. According to Moorthy (2004), the amylose content of tapioca flour is in the range of 20-27%. Cassava has a high amylopectin content, with the addition of aloe vera, it is hoped that the gel will be safer and better for patients with sensitive skin problems (Jahan, 2020).Methods: Experimental with true experimental design using posttest only control group design.Results: Three different gel formulations were obtained, including A2 gel with a composition of 25 grams of cassava flour, 4 grams of aloe vera gel, 0.1 grams of methyl paraben and 75 mL of distilled water. Gel B2 with a composition of 25 grams of cassava flour, 4 grams of aloe vera gel, 0.1 grams of methyl paraben, 100 mL of distilled water. The composition of the C2 gel includes 25 grams of cassava flour, 4 grams of aloe vera gel, 0.1 grams of methyl paraben and 125 mL of distilled water. Gel A2 has a standard pH and spreadability.Conclusion: The results of the evaluation of the formula have shown conformity with the parameters set so that gel A2 was chosen to be the optimum formula. Keyword : Cassava, Gel, Ultrasonography.

Abstract

Background: A brain tumor is a mass of brain cells that grow abnormally. In radiological terms, a brain tumor is called a space occupying lesion (SOL) which generally means a lump. Radiologists or radiology specialists in identifying brain tumors will analyze the results of Magnetic Resonance Imaging (MRI) Brain images with post-processing techniques using a menu in a 3D editor called the region growing technique.Methods:This type of research is a quasi-experimental research design using Posttest Only Without Control Group Design. The research plan will be carried out at Hermina Hospital Bekasi using 32 samples of brain tumor MRI images, the sample size is obtained by the sample size formula for two paired populations according to Sastroasmoro (2011). Bivariate data analysis, if the data is normally distributed (p value 0.05), then the Paired T-test statistical test is performed and if the data is not normally distributed (p value 0.05) the Wilcoxon statistical test is performed.Results: The results of the analysis of brain tumors are followed by manual measurement of tumor volume using the region growing technique. It requires sufficient expertise and experience so that the diagnosis of tumor volume is given precisely and accurately so that its handling can be carried out wisely Evaluation of MRI images requires high accuracy, but doctors can make mistakes because the diagnosis is still done manually, such as errors in diagnosing the location of the tumor and the size of the object. The very complex structure of the human brain also presents its own difficulties in identifying brain tumors. Subjective factors can also affect manual doctor evaluations such as fatigue and uncontrolled time in evaluating an MRI image so that a digital image processing program is needed that can be done with a computational machine to assist doctors in evaluating an MRI image automatically. The active contour method can solve the problem of topological changes in a brain tumor image.Conclusion: The active contour method is able to classify images with high accuracy. So that it can increase the accuracy of the segmentation process for easy and fast medical diagnosis. The calculation of the volume of brain tumors can be done using the binaryization method which has been segmented through the final image produced by the active contour method. Tumor segmentation and automatic tumor volume calculation have great potential in clinical treatment by freeing doctors from the burden of manual labeling, digital image processing of brain tumors using the active contour method can be used as a complement to the MRI modality that radiologists can use in calculating brain tumor mass volume calculations

Abstract

Background: One variation of pulse sequence used in MRI Brain examination is Diffusion Weighted Image (DWI). In the DWI sequence, the value of 'b' which the operator must choose when setting the parameters, affects the signal intensity. In radiology installations, radiographers often use a 'b' value of 1000 s/mm2 with various pathologies. The purpose of this study was to determine the effect of setting the value of 'b' (1000.1500.2000 s/mm2) on image information and to determine the best setting of the three selected 'b' values in generating DWI signals for cases of intracranial tumors.Methods: This research is experimental study. This research uses MR GE 1.5 Tesla. 6 radiographic images were created with three 'b' value settings. Three radiologists then assessed areas of white matter, gray matter, proc. coronoid, basal ganglia and tumor lesions. The results were then analyzed using the Friedman statistical test.Results: The results showed that there were differences in signal intensity and image quality between the three setting values of 'b' with p value 0.005. The mean rank indicates that the best setting 'b' value in producing high signal intensity in Basal ganglia, Proc. coronoid and tumor lesions is 1500 s/mm2 (Mean rank: 2.75 and 2.42). then for white matter and gray matter the best 'b' value setting is 1000 s/mm2 (average rating: 2.50).Conclusion: There is a significant difference in MRI Brain image information with variations in the "b" values of 1000 s/mm2, 1500 s/mm2 and 2000 s/mm2 with pulse sequence Diffusion Weighted Imaging (DWI) using GE 1.5 Tesla MRI modality in patients with intracranial tumors (p 0.05). Keyword : DWI , ‘b’ value,  Brain, Tumor, image information

Abstract

Pediatric Ct Scan is a quick and painless examination that uses x-ray equipment to create detailed images of the child’s internal organs, bones, soft tissues and blood vessels. Pediatric Ct Scan examinations are used to help diagnose abdominal pain and evaluate trauma injuries. This type of research is quantitave research using analytical observational methods, this research has been done on 25 April- 16 June 2022 with 10 patient’s famillies as research sample. Measurement of the radiation dose of the tyroid organ of the patien.s famillis using a DMC 300 pendose measuring instrument by means of a tool tied to the left side of the patient’s famillies neck (the part that is not covered by the apron). The results of the study of the radiation dose of the tyroid organs of the patient’s family produced avarage for a scanogram of 0,001 mSb, for scanning results an average of 0,0187 mSv was obtained, the average value of the quivalent dose was 0,0187 mSv and the average value of the effective dose was 0,0000748 mSv. The average obtained is still categorized as safe for the general public when compared to PERKA BAPETEN no.8 of 2011.

Abstract

Background: Evaluation of brain tumor MRI image results performed by radiologists employing the linear measurement method has several weaknesses and is sensitive to subjectivity. Purpose: To compare the results of measurements and calculations of brain tumors utilizing the linear measurement method on the Siemens 1.5 Tesla MRI modality employing pulse sequence spin echo with T1 contrast weighting compared with the results of measurements and calculations of brain tumors utilizing the active contour segmentation method. Method: An experimental study was conducted on 32 MRI images. Result: The study’s findings indicated that the linear measurement was more significant than the active contour segmentation method (p-value<0,05). The results were obtained by calculating the sensitivity and specificity values of the diagnostic test, which were calculated to be 87.5%. Conclusion: The active contour segmentation method applied to pulse sequence spin-echo T1-weighted contrast can be utilized as an alternative measurement and calculation of brain tumors with a sensitivity and specificity value of 87.5%. Further research suggests developing a Matlab application to compare the results of measurements and calculations of brain tumors on acquiring 3D image magnetic resonance imaging data.
