Abstract

Background : According to the theory, Neck MSCT examination were performed using monophasic injection techniques. Split-bolus is an innovative technique that divides intravenous (IV) contrast media into two or three boluses and combines phase images in single scanning. The MSCT split-bolus scan with a combination of parenchymal and vascular enhancement is a valid alternative approach compared to the standard monophasic MSCT protocol. The purpose of this study was to determine the split-bolus technique in neck MSCT examination and its role in the quality of the image. Method : This research is a descriptive qualitative study with a literature review study method. Data is collected by the documentation method. The electronic database was searched using the keywords "head and neck" AND ("contrast" OR "injection") AND ("Split bolus" OR "Biphasic Contrast" OR "Dual bolus" OR "Double bolus" OR "Multi-phase" OR "Quadruple-Phase"). The inclusion criteria used were a research article on a split-bolus technique in a single scan on MSCT neck examination. Three articles met the inclusion criteria. Data analysis was performed using the annotated bibliography method. Result : The results of this study indicate that the contrast media used in the MSCT examination of the neck with a split-bolus technique are non-ionic iodine contrast media with a total volume of 80-100 mL and a concentration of 300-370 mg / mL. Contrast media injection is done by dividing contrast media in the first and second boluses using a ratio of 3 : 2 or 1 : 1 of the total volume of contrast media followed by saline injection. The flow rate used is 2 - 3 mL / s with a fixed delay time between 70 - 120 seconds. The split - bolus techniques have a role in contrast resolution of image quality. The image quality produced on neck MSCT examination using split bolus technique can increase vaskular and tumor enhancement without reducing parenchymal enhancement and lesions. In a patient with metastasis, this technique can reduce artifacts due to excessive contrast media in the arteries and veins so the lymph nodes appear more clearly. Conclusion : Based on the result, the split - bolus techniques have a role in contrast resolution of image quality.

Abstract

Background: Clavicula examination procedure with clinical fractures in radiology installation RAA Soewondo Pati Hospital was using only Antero Posterior (AP) projection. The purpose of this research is to know the clavicle examination procedure with clinical fractures and find out the reasons for using Antero Posterior (AP) projections. Methods: Type of this research is qualitative research with approach case studies. Data were collected by observation, in-depth interviews, and documentation. This research took place in the radiology installation of RAA Soewondo Pati Hospital. Data analysis was carried out with interactive model three steps, namely data collection, data reduction, data presentation. Results: The results showed the clavicula examination procedure with clinical fractures in radiology installation RAA Soewondo Pati Hospital was using Antero Posterior (AP) projection. Conclusions: The reason for using this projections is because this projections have provided diagnostic anatomy information and its enough to make a the diagnosis. But to show costae 1 and 2 and clavicle appear more clear and not superposition each other should use AP Axial projections.

Abstract

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%.
