Abstract

Background: In Indonesia, nasopharyngeal cancer ranks 4th most in malignancies. As a method of treatment, the development of radiotherapy has made it possible to give high doses to tumors with little risk of healthy tissue, but still maintain accuracy by performing geometry verification procedures. The purpose of this study was to determine the geometry verification procedure of nasopharyngeal cancer with EPID on the Linac plane in RSUP Dr. Kariadi Semarang; the average geometric shift that occurs and why is only done before fractions 1 and 4 only.Methods: This type of research is qualitative with a case study approach. The data is taken from February 2019 to June 2019 by the method of observation, documentation and interviews. The data obtained were analyzed by interactive models, making transcripts of interviews then reduced and processed in the form of open coding, presented in the form of quotations and concluded.Results: The results showed that the geometry verification procedure was started by making a calendar treatment, adjusting the patient's setup at the origin point, switching to the iso center point. Take the image portal with EPID AP and Lateral projections. Match image portals with DRR images. Then the geometric shift data were obtained with a mean shift from the iso center in 5 patient samples: vertical axis 0.15 cm to superior; longitudinal -0.01 cm anteriorly and laterally 0.04 cm to the right. Tolerance limit of 0.3 cm. This verification is only done before fractions 1 and 4 because of the high service load.Conclusion: The geometry verification procedure has been going well with the results of the shift is still below the tolerance limit. Verification information before the 1st and 4th fractions was not enough to assess the accuracy of the irradiation carried out properly maintained.

Abstract

Background: Radiological examination in cervical services, Radiographers often opening the collimation wider of the size of the imaging plate for fear of being cut. This is done because it is supported by the image cropping facility on the CR. So there is a habit of opening the collimation width as wide as the imaging plate, which is often done with the assumption that it is better to widen the collimation than cut off the object. Obviously this will increase the radiation dose in patients with basic limitations. According to ICRP, patient safety must refer to the principle of radiation protection ALARA namely in the shortest possible time to get quality radiographs and patients receive the most minimum radiation exposure as possible.Methods: This research is a descriptive analytic research conducted with a cross sectional approach. The study was conducted by varying the radiation field area to be used for cervical examination. There are 10 variations of collimation area with 3 (three) exposures in each collimation. Then measured contrast, noise and radiation dose. Radiation dose is calculated by means of a babyline device.Results: The results showed that the collimation setting did not affect contrast radiography in CR because collimation was not the main factor that could affect contrast radiography on CR. The collimation setting on cervical radiography has an effect on the radiation dose, so it is necessary to adjust the collimation to get the minimum dose possible. The most optimal collimation area on cervical radiographic examination was obtained at a size of 12 x 24 cm with the smallest noise reception and dose compared to others and had higher contrast. Average contrast value achieved was 0.45 with a dose of 39.23 µGy.Conclusion: The collimation setting on cervical radiography has an effect on the radiation dose, so it is very necessary to adjust the collimation to get the minimum dose possible. The most optimal collimation area on cervical radiographic examination is obtained at a size of 12 x 24 cm with the smallest noise reception and dose compared to others and has a higher contrast.

Abstract

Backgroud: MRI examination of brain often find patients who are less cooperative, thus requiring rapid acquisition techniques. Parallel imaging technique sensitivity encoding (SENSE) utilizing the spatial information RF coil phased array to reduce the acquisition time by reducing the number of sampling lines K space therefore produce quality and good spatial resolution, but its has the limitations, namely the reduction of signal to noise ratio (SNR). SENSE is used along with pulse sequence one of turbo spin echo (TSE). The purpose of this research was to determine the differences in SNR and scan time on T2 weighted TSE MRI of brain axial slices between use SENSE with no SENSE. Methods: This research is a quantitative study with an experimental approach. Data were collected from May to June 2016 in Radiology Unit Premier Bintaro Hospital by calculating the SNR value through software for the region of interest (ROI) and calculate the scan time through the scan timer on the workstation monitor. Data was analyzed by statistical tests with SPSS 16 software using paired T-test and descriptive. Results: From the statistical test result known that the SNR on T2 TSE between use SENSE with no SENSE the p-value 0,000 (p <0,05). This is because the encoding between the two images are different, the image of the T2 TSE without SENSE contained use of pulses in 1800 approached TE effectively so shallow gradients produce echo maximum, while the image of the T2 TSE using SENSE there is a reduction in line phase encoding in the K space and their g-factor causing reduced SNR. From the analysis descriptively known that the scan time on T2 TSE between use SENSE with no SENSE by reducing scan time for 1 minute 24 seconds (49,01%). This is because the acquisition techniques are different between the two images, the image without SENSE T2 TSE contained ETL in the filling K space, while the T2 TSE images using SENSE R-factors are causing sampling did not fill all the K space so that the scanning time is reduced. Conclusion: There is a difference in SNR and scan time of T2 weighted TSE MRI of brain axial slices between use SENSE with no SENSE

Abstract

Meningiomas commonly manifest as granulations, dense clusters exhibiting hyperintense signals on the meningeal layers and close to cranial nerves. Detailed and isotropic imaging are key in the diagnostic evaluation. Nevertheless, standard MRI sequences have been inadequate in capturing these granulations, incorporating the T2 3D CISS axial sequence for improved visualization. Our case study aims to meticulously evaluate the diagnostic imaging strategies used for meningioma cases, explicitly focusing on cranial nerve imaging. The MRI protocol encompassed axial, coronal, and sagittal T2_TSE and DWI sequences and post-contrast T1-weighted imaging. A detailed calibration of the 3D CISS sequence parameters was performed to enhance the imaging of cranial nerves affected by the suspected meningioma. Our findings highlight the necessity of a meticulous MRI protocol, which includes precise imaging sequences, to evaluate meningiomas effectively, particularly for assessing the potential involvement of the cranial nerves.
