Abstract

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.

Abstract

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 manufacturers 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.

Abstract

Backgroun: Dark room is the room where the film is being processed as the final stage of the radiographic process, beside its function as a place of handling film and film storage. According to the MSDS, chemical liquid used in film processing can affect human health. It’s spill can cause irritation and burns on skin and eyes, irritation and injury to the digestive tract, while its  mist or dried residue can cause irritation of the respiratory tract. Good dark room air circulation is required.Methods: The study was observational study with measurement data retrieval techniques in the darkroom of four hospitals. The collected data then compared to the air quality requirement according Kepmenkes RI No.1204/Menkes/SK/X/2004 and No.1405/Menkes/SK/XI/2002.Result: The results showed that the physical air quality including temperature and humidity in the 1st, 2nd, 3rd and 4th darkroom was higher than the standards. The average air flow in the 1st, 2nd and 3rd  darkroom were up to standards, but there was no airflow in the 4th darkroom. Results of ambient air quality measurements  in the 1st, 2nd, 3rd and 4th including CO, NO2, SO2 and T.VOC did not meet the standards, while the presence of H2S and NH3 were not detected.Conclusion: Total dust levels in the 1st, 3rd and 4th  darkroom did not exceed the maximum concentration in indoor air (< 0.15 mg/m3), while the 2nd darkroom exceed the standard (> 0, 15 mg/m3). Using of air-conditioning and a dehumidifier with periodic maintenance is needed to resolve the discrepancy physical air quality, beside periodic cleaning and indoor air excahnge maintenance to resolve high levels of dust and gas pollutants.

Abstract

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
