Background: Chest radiographic examination often does not use a grid even though the thorax is an object that has a thickness of more than 10 cm so it must use a grid. This study aims to determine the differences and the degree of change in Contrast to Noise Ratio on PA radiographs between using a grid and without using a grid.Methods: This type of research is a pre-experimental quantitative. The research subject is a radiological image of PA thorax made using the grid (50 patients) and without using the grid (patient). The image is analyzed by pixel value using Dicom softwareResults: There is a difference in contrast values on the PA radiographs between those using the Grid and without using the Grid (p-value 0.001). The average value of the contrast on the chest radiograph using a Grid is 2283.60, while the one without using a Grid is 1878.58. Noise value also shows that there is a difference between chest radiographs of PA images using Grid without using Grid (p-value = 0.001). The average thorax photo noise using Grid is 25.32, paired using Grid is 17.84. Statistical test on the value of Contrast to Noise Ratio (CNR) shows that there is a difference between radiographs of PA chest radiography using Grid without Grid (p-value 0.001). The average CNR radiograph of the PA thorax PA using Grid is 100.79, while the CNR value of the radiograph of thorax PA without using Grid is 125.62.Conclusions: There is a Contrast difference between using a grid and without using a grid (p-value 0.001). There is a Noise difference in PA radiographs between using a grid and without using a grid (p-value = 0.001). There is a difference in Contrast to Noise Ratio on the PA chest radiograph between using a grid and without using a grid (p-value 0.001).

Background: Patients with HNP cases have a bigger chance to do a movement during MRI examination, and it causes poor MRI image. Quick time of MRI examination is needed to produce an optimal image. The technique of parallel imaging is a technique that can increase the speed of MRI data acquisition by passing through several lines of phase encoding in k-space. The GRAPPA technique is one of the methods used to reconstruct data on MRI parallel imaging techniques with better overall image quality. The technique of parallel imaging has a special parameter called acceleration factor. Acceleration factor (R-factor) will affect scan time. The purpose of this research is to know the difference of diagnostic image characteristic which is resulted in applying acceleration factor 2, 3 and 4 in parallel imaging of GRAPPA method and know the optimal acceleration factor to obtain MRI image of lumbar HNP case. Methods: This research type is quantitative research with descriptive approach. The study was conducted by MRI Siemens 3 T in RSUD Dr. Soedono Madiun. The data were 30 MRI images of lumbar sagittal of HNP cases on T2WI FSE with acceleration factor 2, 3 and 4 GRAPPA methods Result: The results of this study indicate that there are differences in diagnostic image characteristics in the application of acceleration factor 2 and 4, 3 and 4 with VGA test. Acceleration factor value optimal with VGC test known is acceleration factor 2 and 3 Conclusion: Based on the result there were differencediagnostic image characteristics of MRI Lumbar in sagital plane Fast Spin Echo (FSE)sequence with variation acceleration factor 2, 3 and 4 parallel imaging GRAPPA methode in case Herniated Nucleus Pulposus (HN0). The optimal value of variation acceleration factor value for MRI Lumbar examination of Heniated Nucleus Pulposus (HNP) is 2 dan 3.

Background : Application of MRS itself to measure the N-Acetyl Aspartate (NAA) content in tumour, stroake and epilepsy. Contents of NAA has important role in the central nervous system. Examination of MRS itself should be included to support the patient diagnose. Time echo is an important parameter which affect the metabolite spectrum. So, measurement of metabolic value using variants of TE which is 35, 144, 288 ms, are the main idea. The purpose of this research to know the measurable metabolic which use of variants of TE and to know which TE has show the smallest difference with normal metabolic value. Methods : This research is a quantitative descriptive method. Reasearch subject is Radiographer which has competence dan enough experience in MRI. Research samples using 10 person who become the research probandus. The acquisition is do three times on right temporal lobe with TE value 35, 144 and 288 ms. Another parameter which controlled is TR 2000 ms, Single Voxel Spectroscopy (SVS) acquisition sized 31.7mm3 with Point Resolved Spatial Selection (PRESS) pulse sequence. Measurable metabolic aspect which will be evaluate is N-Acetyl aspartate (NAA), Choline (Cho) and Creatine (Cr). Data processing and analysis is do by calculate the spectroscopy spectrum intensity so obtained the measurable metabolic value then using univariate analysis or descriptive analysis. Results : Results of measurable metabolites is the longer TE use so the metabolic spectrum will be decrease on NAA (35 ms: 8.2, 144 ms: 7.3, 288 ms: 5.4), Cr (35 ms: 6.8, 144 ms: 5.8, 288 ms: 3.8) and Cho (35 ms: 6.9, 144 ms: 6.0, 288 ms: 4.4). Then on the calculate of metabolic value difference with normal metabolic value, the longer TE use so the difference will be increase on NAA (35 ms: 1.8, 144 ms: 2.7, 288 ms: 4.6), Cr (35 ms: 1.2, 144 ms: 2.2, 288 ms: 4.2) and Cho (35 ms: 0.1, 144 ms: 1.0, 288 ms: 2.6). Conclusion : So can be assumed that using TE 35 ms on MRS will obtain the metabolic spectrum which close to normal metabolic value. But, short TE unable to show the Lactate spectrum in case of brain tissue abscess, so it’s required to scanning using TE 35 ms and 144 ms or 288 ms as comparison to get more accurate measurable metabolic value.

Background : Image quality Abdomen CT scan is said to be either indicated by low noise or image noise values within acceptable standard limits. One of the parameters affecting image noise is mAs. On CT Scan aircraft there is an auto mAs setting facility called Sure exposure to ensure constant image quality at the lowest possible dose. The purpose of this study was to determine the difference of anatomical information to the use of sure exposure protocol and without sure exposure on CT scan of Abdomen and to know better protocols in producing quality on CT Scan Abdomen between usage protocol sure exposure and without sure exposure. Method : This research is a kind of quantitative research with experimental approach. This study used the CT Scan Multislice 128 plane on CT scan of Abdomen with the use of sure exposure protocol and without sure exposure. The results were obtained based on respondents assessment through Liver, Spleen, Adrenal Gland, Kidney, Pancreas and Abdominal Wall. Analyze this research data using statistical test. Result : The results of the questionnaires of respondents on liver, spleen, adrenal gland, kidney, pancreas and abdominal wall showed no significant difference. This is followed by the value of Mann Whitney's overall significance of the abdominal anatomy is 0.549 (p value> 0.05). Protocol Sure Exposure is better on the organ of adrenal glands, kidneys and pancreas, whereas protocols without sure exposure are better in liver, spleen, kidney, pancreas, and abdominal wall. The use of protocols without sure exposure better in generating information. Conclusion : In general the protocol of sure exposure and without sure exposure has the same clarity of anatomical information. But the protocol without a sure exposure has more information than the sure exposure protocol.

Background: The existence of a foreign object in the body generally can interfere with the metabolism of the body, so it can be life-threatening. Therefore it is necessary to take medical action in the form of surgery as soon as possible and precisely with x-ray examination as the guiding. With the development of the use of CR modalities, the method of determining foreign objects with the tools in the CR is considered, which is then called the quadrant method. And this study aims to explain the procedure and then the results are compared with the triangulation method which is a method of determining the depth of foreign objects previously used. Methods: The type of research carried out is exploratory description research with an experimental approach. Where the radiograph was made in cases of foreign objects with 2 methods, namely the triangulation method and quadrant method using CR. First made phantom organ femur, humerus, and thorax in which a foreign object is placed in it. The position of a foreign object is actually measured first and then the results of measuring the depth of a foreign object using the quadrant and triangulation method are compared with the results of the measurement of the actual foreign object. Results: The results showed that the making of radiographs with quadrant methods as well as triangulation methods both used 2 exposures with an x-ray so that the radiation exposure factor obtained by patients in both methods was not much different. Whereas from the comparison of the results of the measurements of the two methods it was found that the triangulation method was better than the quadrant method with smaller measurement differences when compared with the actual measurement of foreign objects. This is because the triangulation method has displayed measurement results based on a formula that uses mathematical calculations by calculating the distance and magnification of objects. And this is not obtained in the quadrant method where measurements are based on the data presented on the CR monitor screen without calculating the distance and magnification of the object first. Conclusion: Radiographic examination procedure determines the depth of foreign matter quadrant method using a computer Radiography is carried out with two projections namely anteroposterior and lateral. While the difference in the depth of the foreign body quadrant method with the depth of the foreign body is actually found that the accuracy of the measurements carried out by the triangulation method is better than the measurements carried out by the quadrant method

Conclusion: Radiographic examination procedure determines the depth of foreign matter quadrant method using a computer Radiography is carried out with two projections namely anteroposterior and lateral. While the difference in the depth of the foreign body quadrant method with the depth of the foreign body is actually found that the accuracy of the measurements carried out by the triangulation method is better than the measurements carried out by the quadrant method","PeriodicalId":205622,"journal":{"name":"Jurnal Imejing Diagnostik (JImeD)","volume":"57 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132175132","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
Introduction: Pelvic MRI examination in endometriosis cases does not theoretically use an ultrasonic gel that is inserted into the vagina and rectum, but also for sequences used without using the T1 sequence. Sagittal cut fat suppression. Radiology Installation Mayapada Hospital, South Jakarta for Pelvic MRI examination with Endometriosis cases using Gel and T1_SPIR sequences from these differences the authors are interested in exploring information about Pelvic MRI examination in Endometriosis cases at Radiology Installation Mayapada Hospital, South Jakarta with the aim of knowing the role of gel and sequencing of T1_SPIR Sagittal pieces. Method: This type of research is qualitative research with a case study approach. The method of data collection is done by observation, in-depth interviews with radiographers, radiology specialists and sending doctors and documentation. Data analysis is done by an interactive model, then the data is presented in the form of the narrative text so that conclusions can be drawn. Results: The results showed that Pelvic MRI examination using Ultrasonic Gel in Endometriosis Cases in Mayapada Hospital Radiology Installation in South Jakarta used ultrasonic gel in the 50cc and 150cc vaginal organs, the sequences used were: T2W_TSE, T2W_SPIR, T1_SPIR, T1W, T2_FFE on Sagittal snippets, T2W_TSE, T2W_SPAIR, T1W_SPIR on coronal chunks, T1W_TSE, T1W_TSE_SPIR, T2W_TSE on axial chunks and DWI_3b_RT SENSE on axial chunks and SSh_URETER. The reason for using ultrasonic gel on MRI examination in the Pelvis at the Mayapada Hospital Jakarta Radiology Installation is to see a clear difference between normal tissue and pathological tissue and expressly demarcate organ boundaries and play a role in widening the vaginal cavity and rectum. The reason for adding the sagittal cut T1_SPIR sequence in the case of Endometriosis at the Mayapada Hospital Radiology Installation in South Jakarta is to show lesions suspected of blood or other intensity and to ensure bleeding.

Background : TR (Time Repetition) is an MRI parameter. TR controls the amount of longitudinal magnetization recovery before the next RF pulse. TR parameter is one of parameters that can affect image quality and image information. Long TR arrangements can increase SNR (Signal To Noise Ratio), CNR (Contrast To Noise Ratio) and provide better contrast, but increase the examination time. The purpose of this research is to know the effect of TR to image quality, difference of image information and TR optimal on MRI Lumbal sequence T2 FSE sagittal. Methods : The type of this research is quantitative research with experimental approach. The sample of research used is 6 probandus. TR variations used are TR 2000, 2500, 3000, 3500, 4000 with other parameters controlled. Aspects of image quality and image information values assessed in this study include Corpus Vertebrae, Discus Vertebrae, Cerebro Spinal Fluid (CSF), Medulla Spinalis, and Soft Tissue. Processing and analysis of image quality data is done by data normality test using shapiro-wilk, then test influence correlation pearson, linear regression and repeated anova. and for image information is done normality data test using shapiro-wilk, and friedman test. Result : The results of the test analysis showed that there was a TR effect on SNR image quality (p = 0.001) and CNR (p = 0.007) with (p <0.05) on all assessed organs. There is a difference in image information of MRI Lumbal T2 FSE sequence of sagittal pieces on Time Repetition variation with significance value (p <0.05). The optimal TR value on image quality is found on TR 4000 variation with mean of highest mean rank that is 42.82. While the optimal TR value on the image information is on the variation of TR 3000 with the highest mean mean rank is 3.25. TR 3000 is considered to produce better image information and is considered optimal on MRI Lumbal sequences of T2 FSE sagittal fragments compared to other TR variations with a duration of examination time of 2 minutes 30 seconds. Conclusion: Based on the results that good variation TR used on MRI Lumbal examination sequence T2 FSE sagital view is TR 3000 with best image qualit, informative image information and short scanning time.
