Background: One step to create a good image is by doing slice thickness reconstruction. Slice thickness is thick slices or pieces of the object checked out. The examination procedure of MSCT in case of Cervical trauma in Radiology Installation RSUD Tugurejo Semarang using slice thickness 3 mm. This contrasts with Seeram (2016), which explained that the examination of adult MSCT Cervical Spine using slice thickness between 1-2 mm. This research aims to know the difference of anatomic information resulted by 5 slice thickness variation in MSCT Cervical Spine and to find out which slice thickness can provide optimum anatomic information.Methods: The type of this research is quantitative with an experimental approach. Data is performed by reconstructing the 5 images of MSCT cervical of trauma patients using 5 slice thickness variation which is 1 mm, 1.5 mm, 2 mm, 2.5 mm and 3 mm. The final images are evaluated by two Respondents to see the differences in anatomic information and then analyzed by using a different test (Friedman Test) from the SPSS version 24.0.Results: The results showed there is a significant difference in anatomic information on the corpus, lamina, spinous process, transverse process and fragment fracture between variations in slice thickness of 1 mm, 1.5 mm, 2 mm, 2.5 mm, and 3 mm on the MSCT Cervical examination with a significance value of 0,000 or p 0.05.Conclusion: The most optimal slice thickness to provide anatomic information on the cervical MSCT examination is 1 mm slice thickness with a mean rank value of 3.64.
Background : One effective technique is contained in a CT Scan to decrease the amount of radiation dose that is received in the use of automatic exposure control (AEC). AEC system of Siemens equipment is called Care Dose 4D. The research is based on unused of the application Care Dose 4D on CT Scan Imaging. The purpose of the research is to determine the differences of image noise and the differences of radiation doses (CTDI) using care dose 4D and Non Care Dose 4D in Siemens MSCT.Methods :The research was quantitative study with experimental approaches that is tested on four water phantom size type. Analysts data is done by statistical tests of Paired T-Test Samples to test the hypothesis and the level difference image information. In this statistical analysis is determined the level of confidence (level of Significance) with a value of α = 0.05.Results : On the using of Nasopharing protocol for children with 130 kV and 130 mAs parameters, using of Care Dose 4D has ability to decrease the image noise value is compared with non Care Dose 4D application. While the adult Nasopharing protocol with 130 kV and 220 mAs parameters, Care Dose 4D doesn’t provide enough impact in the reduction of image noise value if compared with conventional techniques or without using Care Dose 4D applications. Using of children nasopharing protocol application Care Dose 4D even increase radiation closes high enough value in CTDI vol that is 5,03 mGy, but using Nasopharing Care Dose 4D applications for adult can decrease radiation doses high enough value in CTDIvol, that is 2,64 mGy.Conclusion : On the use of children nasopharing protocol application Care Dose 4D even increase radiation closes high enough value in CTDI vol that is 5,03 mGy, while the adult Nasopharing using Care Dose 4D applications can decrease radiation doses high enough value in CTDIvol, that is 2,64 mGy.
Background : Before conducting an MRI examination, there will be a positioning. One of the positions carried out is the placement of isocenter. Isocenter is a magnetic center point where each gradient will be centered at that midpoint (Brown and Semelka, 2010). Different isocenter placements can affect image quality (Caramanos et al, 2010). In practical experience in the Telogorejo Semarang SMC Hospital, the placement of the isocenter in the nation while in Dr. Soetomo and Premier Surabaya Hospital placed Isocenter in Glabella. To examine the effect of isocenter placement on image quality and MRI brain T1 fast spin echo anatomical image information in the nasion and glabella and determine the optimal isocenter placement between the nasion and glabella. Method : This type of research is quantitative with an experimental approach. This research was conducted at Telogorejo SMC Hospital Semarang. Data in the form of 16 MRI images of sagittal brain pieces of T1 Fast Spin Echo weighting on isocenter placement in the nasion and glabella of 8 volunteers. Testing is done using the SPSS program where the image quality is analyzed by linear regression test, while for anatomical image information is analyzed by the Wilcoxon test. Result : The results of this study indicate that there is an effect of isocenter placement on the quality of MRI brain images of T1 fast spin echo sagittal pieces as seen from p value SNR (0.039) and CNR (0.010) <0.05 and from SNR percentage effect of 16.85% while CNR of 5, 8%. in addition to the influence, there are also differences in the anatomical image information of the MRI brain T1 fast spin echo sagittal section which is seen from the p value generated is 0.001 <0.05. Conclusion : Judging from the mean rank per anatomy, isocenter placement in the nasion is optimal in providing information on the mesencephalon, medulla oblongata, and cerebral subarachnoid space.
Background : Coronary Artery By Pass Grafting (CABG) is one of the intervention treatments of Coronary Heart Disease (CHD), by creating a new channel through the coronary artery which is narrowed or blocked. The purpose of this research is to know the procedure of Cardiac CT examination with CABG case, acceptable Heart Rate range and how to lower Heart Rate range and how to lower Heart Rate at Radiologt Installation of MRCCC Siloam Hospital Semanggi.Methods : This type of research is qualitative with case study approach. The data were collected from April - June 2017 at Radiology Installation of MRCCC Siloam Hospital Semanggi by observation method, interview with 3 radiographers, 2 radiology specialists and 1 sending doctor and documentation. Data obtained from the study were analyzed by interactive model, with data reduction stage, data presentation and conclusion.Result : The results of this study stated that the procedure of Cardiac CT examination with CABG scan start from subclavia to the diaphragm to show the graft, the amount of contrast media used 20 cc more and the amount of saline used 10 cc more, Beta Blocker and Vasilidator not given because CT Scan with 256 slices work quickly so as to suppress the movement of the heart with optimal. Acceptable Heart Rate range is 65 - 80 bpm. How to lower high Heart Rate by giving patients education one day before the examination, which is does not consume drugs which can increase Heart Rate and do not perform heavy activities. Patients with unstable Heart Rate should be given Beta Blocker 2-3 days before the examinationConlusion : Based on the results of the study, the range of CT Cardiac examination with CABG cases differs from the usual cardiac CT range and using MSCT 256 radiology specialists slice does not need to consider the patient's heart rate
Background: Abdominal MSCT has better sensitivity and specificity, however its radiation exposure is high. Adaptive Iterative Dose Reduction (AIDR) 3D is an iterative reconstruction technology on Toshiba which produces a better image quality by reducing noise and streak artifacts in low dose. Based on author’s observation, abdominal MSCT performed at the hospital uses a standard routine abdominal MSCT protocol without adjusting the level of AIDR 3D. AIDR 3D has several strength level allowing an optimal image quality. This study was aimed to explain the role of AIDR 3D in improving the image quality and radiation dose of abdominal MSCT. Methods: This research method is descriptive with the literature study approach, by collecting articles from ProQuest, Google Scholar, PubMed, SpringerLink, and ScienceDirect about the role of AIDR 3D on abdominal MSCT published 2013-2020. The articles were selected according to the inclusion criteria. So there were 4 relevant journals which were then analyzed by making a journal summary, evaluating, giving opinions so that conclusions and suggestions can be drawn. Result: The results showed that AIDR 3D can improve the image quality of abdominal MSCT by reducing noise, artifacts and increasing CNR, SNR, image sharpness. Noise reduction and CNR increase, the most prominent SNR is found in AIDR 3D Strong, followed by Standard and Mild. AIDR 3D can reduce radiation doses better without reducing image quality Conclusion: AIDR 3D can improve image quality on abdominal MSCT and the use of integrated AIDR 3D SUREExposore 3D can reduce radiation doses better without reducing image quality. Reduction of radiation dose between 23% to 76%.
