Background: Magnetic Resonance Imaging (MRI) examination of the cervical spine axial slices with T2 weighted flow is often contained artifacts that interfere image result, so it uses flow compensation technique. Axial slices of T2 weighted may use TSE or GRE sequences. This research aims to determine differences in MRI image information of cervical spine axial slices using flow compensation between T2 weighted turbo spin echo (TSE) and gradient echo (GRE) sequences and to get better image information between that both sequences.Methods: This research was a quantitative study with an experimental approach. Data were collected from May to June 2016 in Radiology Installation of Haji Surabaya Hospital using a questionnaire to three respondents. Data were analyzed by statistical tests with SPSS 16 software using Wilcoxon test to determine differences level in image information between T2 weighted TSE and GRE sequences, mean rank value from Wilcoxon test and crosstabulation test to get better image information.Results: There were differences in MRI image information of cervical spine axial slices with using flow compensation between T2 weighted TSE and GRE sequences with p-value was 0.005 (p 0.05). This difference was due to the differences of parameter characteristics between both sequences and T2* GRE was more sensitive to flow to the organ than the TSE. Better MRI image information of cervical spine axial slices using flow compensation was T2* GRE sequence shown by the mean rank 5.50.T2*. GRE was better than T2 TSE because it could show the anatomy of the cervical clearly and informatively, the anatomy of the spinal cord, CSF, neural foramen, intraforaminal structure, corpus vertebrae, disc and the minimum artifacts. While on the anatomy of the facet joint was no significant difference between the TSE and GRE sequences.Conclusion: There were differences in the MRI image information of cervical spine axial slices using flow compensation between T2 weighted TSE and GRE sequences. Better image information was T2* GRE sequence.

Background: Callibration of CT number and uniformity is very important to the CT QC program particularly when the program aims to ensure that the CT Scanner equipment operates within the manufacturer's specifications. Since the commercial CT QC phantom is not always available or affordable in the department, a simple, easy and cheap modified CT water phantom design could be useful to support further regular departmental CT QC program.Purpose: (1) to design , a simple and an easy to handle of the modified CT water phantom, and (2) to verify its callibration and measurement functions based on to the gold standard of a commercial CT water phantom.Methods: This study is an experimental research laboratories, where a modified design of CT water phantom is then compared to the comercial gold standard CT water phantom. The commercial CT water phantom uses a cylindrical phantom that contains water with various diameter in sizes. In the modified CT phantom design, it filled with water as well, where the three different size in phantom diameters (15 cm, 20 cm and 32 cm recpectively) created for specific measurement purpose that of the CT Number and uniformity CT Number.Results: Calliberating the function of the modified CT phantom design resulted in the three observasional data. For all different phantom diameters (15, 20 and 32 cm) showed some variation about their CT number and homogenity. Most of the callibration and homogenity tests of the CT number in water deemed significant (cal. CT number for the 20 cm and 32 diameter phantoms, 0,001 0,05 and sig. 0,04 0,05 respectively), instead of that the uniformity test of the phantom sized with 20 cm in diameter (0,432 0,05).Conclussion: A modified water CT phantom designed with 20 cm in diameter could be used for measurement of the CT number uniformity. Yet, measurements of the CT number callibration and uniformity needed to be consider againts from a failed measurement due to the phantom problem design with sizes at 20 and 32 cm in diameters.

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

ABSTRACT Background: The urinary system consists of two kidneys and ureters, urinary bladder, and urethra. Various modalities in radiology can be used to radiologically detect abnormalities in the urinary system, one of which is MSCT. MSCT Urography with tracking technique can identify urolithiasis in the ureters. Iterative reconstruction is used to reduce the dose received by the patient without reducing image quality. Iterative Model Reconstruction (IMR) is the second-generation IR algorithm from the previous generation, namely iDose (Philips Healthcare). This study aims to determine the optimal anatomy image quality with IMR variations on non-contra Urography MSCT images using tracking techniques. Methods: This type of research is an experiment with data obtained from a comparison of the quality of anatomical images from tracking images with IMR variations. Place of data collection at the Radiology Installation of RSUD RAA Soewondo Pati. Time for data collection From 2022. An assessment of the quality of the anatomical images was carried out by 2 radiologists. Data analysis was carried out using the Friedman statistical test method. The level of significance (level of significance) is 95% or α> 0.05 and is done by assessing the p-value. For a significant level of assessment p <0.05 then Ho is rejected and p> 0.05 then Ho is accepted. Results: There are differences in information on each anatomy of the renal parenchyma, pelvic calices, ureters, and perirenal space in the use of IMR variations. The results showed that the optimal IMR variation value was IMR 3 with a mean rank value of 2.7. Increasing the use of IMR levels reduces noise and increases spatial resolution, so that IMR level 3 has the best assessment of anatomical information. Conclusions: We recommend that the non-contrast MSCT Urography examination with the Tracking Technique use IMR 3 which can produce optimal anatomical image information on the kidney parenchyma, pelvic calices, ureters, and perirenal space.

Radiography has an important role in diagnosing a patient's disease, but the equipment used has a considerable risk as a place for the development of nosocomial bacteria which can endanger the patient and radiographer. Cassettes, one of the tools in radiography, have the potential to become a medium for disease transmission and based on previous research it has been proven that there are microorganisms and fungi on the cassettes, so the cassettes need to be cleaned regularly. One of the duties of a radiographer in the field of radiology services is the management of radiology equipment facilities and infrastructure. Cleaning the cassette with 70% alcohol can reduce the number of microorganisms on its surface. The methods in this activity are lectures, simulations, and practice cleaning cassettes with chlorine. The activities were carried out at the Laboratory of the Department of Radiodiagnosis and Radiotherapy Technique at the Semarang Health Polytechnic Ministry with radiographers from hospitals and clinical laboratories in the city of Semarang. The activity begins with the registration, opening, delivering material to the participants, and the simulation of resource persons. Evaluation is done by filling in the pretest and posttest. The evaluation results showed an increase in participants' knowledge of 63% about how to clean cassettes using liquid chlorine to reduce the number of microorganisms on radiographic cassettes. With this training, radiographers are expected to be able to apply cleaning radiographic cassettes with liquid chlorine 0,5% in their respective institutions.

Background: Pulse gradient echo sequences use varying RF excitation pulses and with NMV flips through various angles (not just 90°). Gradient echo has a sensitive susceptibility effect in detecting the presence of blood products (hemorrhage) and calcifications in brain tumors. The SWI and T2 FLASH 2D sequences are part of the pulse sequence gradient echo, where the SWI sequence is a 3D velocity compensated gradient echo and the T2 FLASH 2D sequence is a 2D multi-slice gradient echo. This study aims to determine the differences in axial image diagnostic information and determine the most optimal axial image diagnostic information in MRI brain examinations between SWI and T2 FLASH 2D sequences in brain tumor cases.Methods: This type of research is quantitative with an experimental approach. Data was taken in March 2024 at the Radiology Installation of RSUP Dr. Sardjito Yogyakarta. The sample in this study was 10 patients with brain tumor cases. An assessment was carried out by 2 respondents to assess the criteria for brain tumors. The assessment data from respondents was tested using the Cohen's kappa test to assess reliability between respondents and the Wilcoxon test to determine the level of difference in axial image diagnostic information, then the mean rank was used to determine sequences with better diagnostic image information.Results: The results of the study show that there is a difference in the diagnostic information of axial images on MRI brain examination between SWI and T2 FLASH 2D sequences in tumor cases with a p-value of 0.014. The significant difference is due to the susceptibility effect in both sequences. Based on the Wilcoxon test, the SWI sequence is the most optimal sequence in displaying diagnostic information with a mean rank value of 4.Conclusions: There is a difference of axial image diagnostic information between SWI and T2 FLASH 2D sequence in Brain MRI with brain tumors cases, and SWI sequence produces the most optimal axial image diagnostic information in MRI brain with brain tumor cases.
