Abstract

Background: In the Thoracic Radiography Technique, applying the use of a grid to control scattered radiation almost never occurs, because the organ that is radiologically examined is classified as soft tissue dominance. Consideration of using grid is very important when the thickness of the thoracic organ exceeds 10 cm, thus potentially increasing scattering radiation which will affect the value of the Contrast to Noise Ratio (CNR). The purpose of this study is to examine the difference between the use of grid and non-grid for the chest radiography techniques in the context of CNR values.Methods: In the study, a hundred healthy patient uderwent the chest posteroanterior (PA) radiographic examination, a half of the total patients was examined with grid whereas the rest without the grid embedded. All the resulted images were analyzed by means of the pixel value measurements at the specific organs of interest (costea and pulmonary tissues) in inside and outside of the lung organs, using 1,5 mm of ROI  from Dicom software. The statistical analysis of the CNR values was performed by comparing the results between the groups.Results: There is a significant difference in the contrast values on the PA radiographs between those using the Grid and without using the Grid (p-value 0.001). The average contrast value on the chest radiograph with Grid is 2283.60, while without Grid is 1878.58. In the Noise values, it also deems significance (p-value = 0.001). The average of the noise values employing the Grid in the technique is 25.32, whereas without Grid is 17.84. In the Contrast to Noise Ratio (CNR), the diference seems to be significant (p-value 0.001). The average CNR radiograph of the PA chest using the Grid is 100.79, while the non-grid is 125.62.Conclusions: The application of the grid in radiography technique gives significant difference in the image results (contrast, noise, and CNR), when compare to the radiographic techniques without the grid. Using the grid in the Technique improve the qPA-thoracic quality of the chest images.

Abstract

Background: STIR sequences used in the cervical spine due to the cervical spine is surrounded by lots of fluids and fat, to reinforce the picture of the cervical spine. According to Braun in 2003, TR on STIR used is 4000 ms. Meanwhile, according to Erika J. Ulbribh in 2011, TR on STIR sequences was used that 4860 ms. Based on the writer's observation in several hospitals with the same flight characteristics, the value of TR on STIR sequences different - different. At one hospital using TR 5000 ms, then at other hospitals using the TR 3000 ms. TR value is used based on the theory of 2000 ms.Methods: This research is a quantitative study with an experimental approach. Data were collected from May to June 2016 in the. The subjects of this study are volunteers by using a variation of the value of Time Repetition. It is caused during data capture none of the patients with the diagnosis of the lesion or tumour. image of five variations Repetition Time value is 4090 ms, 5190 ms, 6290 ms, 7390 ms and 8490 ms. Selection of variation based on the value of TR used.Results: From the statistical test result known that There are differences in image information MRI Cervical on the variation of the Time Repetition 4090 ms, TR 5190 ms, TR 6290 ms, TR 7390 ms, and TR 8490 ms to the value of ρ value of 0.000 (ρ 0, 05).That is because Repetition Time (TR) sequences Inversion Recovery (IR) should be long enough to provide opportunities so that Net Magnetization Vectors (NMV) can be in full recovery before the next 180 RF pulse inversion. If TR is too short then each network will be recovery with different levels which will ultimately affect the weighting (weighting) is generated.Conclusion: There are differences in Cervical MRI image information on the variation of the value of 4090 ms Repetition Time, TR 5190 ms, TR 6290 ms, TR 7390 ms, and TR 8490 ms to the value of ρ value of 0.000 (ρ 0.05).

Abstract

Background: Based on observations made by researchers found incorrect apron storage. According to Permenkes No. 1250 of 2009, storage and placement of Pb aprons may not be folded and may not be hung. The purpose of this study is to determine whether or not there are leaks in the apron.Method: Types of quantitative research approaches with experimental approaches. This research was conducted at the radiology installation. The testing is done by giving x-ray exposures on the surface of the apron. Based on the results of the exposure, the extent of the leak is in the apron. The measurement results will be compared with the theory Lambert 2001.Results: According to Lambert, apron leakage is still acceptable if the critical area is less than 15 mm2 and if the non-critical area is less than 670 mm2. The results showed that of the 15 aprons studied three aprons leaked, namely apron 4, apron 7, and apron 13 with each leakage area being 562.84 mm2, 312,174 mm2, 14,304 mm2 71,818 mm2.Conclusion: The total number of tested was 15 aprons, 3 aprons leaked and there was 1 apron which had no leakage. Leakage is caused by often placing an apron on the back of a chair, hanging an apron on a hanger, dropping an apron on the floor, and folding an apron on an examination table. Apron storage should be placed on a special rack in a horizontal position so as not to cause indentations or fractures on the lead.

Abstract

Background: Magnetic Resonance Spectroscopy (MRS) is a method for measuring or assessing changes in the chemical elements of brain tissue in abnormalities such as tumours, stroke, epilepsy, metabolic disorder, infections, and neurodegenerative disease. MRS sequences require techniques to suppress fat and water signals, so the value of metabolic elements such as NAA Choline, Creatine, Lipids, and Lactate not been covered by fat and water. The peak amplitude of metabolic elements in MRS depends on the parameter used in the MRS sequences especially TE. Some studies suggest that variation and combinations of TE can provide more complete information on metabolite element, and can even be used to grading tumour stages.Methods: Type of this research is a qualitative study with an observational approach. Data collection was conducted in June 2019 at Radiology Department with observation method, unstructured interview, and documentation related to Magnetic Resonance Spectroscopy procedures. Data processing and analysis are carried out descriptively related to the result of observation, interview, and documentation.Results: The Head MR Spectroscopy examination procedure is a follow-up procedure of contrast MRI of the head. The main metabolite elements assessed on MRS are NAA, Choline, and Creatine, while those calculated and analyzed are the Area Under Cover (AUC) Integrals which are a collection of NAA and Choline signals. MRS sequences use Multi Voxel Spectroscopy (MVS). Chemical Shift Imaging (CSI) is used to suppress fat and water signals. TE parameter used in MRS sequences is only intermediate 135 ms.
