Abstract

This research aims to determine the assessment of digital image quality from 18 x 24 cm Imaging Plates of the ST (Standard) and HR (High-Resolution) types by engineering the dimensions on intraoral dental radiographic examinations so that we can determine the differences in image quality for each type of imaging. Plate Computed Radiography. The research method took the form of an experiment using the subjective quality assessment method of digital images in intraoral dental radiographic examinations using the object of patients who carried out the examination and brought a referral letter for 60 patients. Analyze image quality by measuring MSE (Mean et al.), PSNR (Peak Signal to Noise) and PIQE (Perception-based Image Quality Evaluator) score. The results of the research show that the analysis of differences in IP FCR ST and HR types with the Mann-Whitney Test shows the significance values of all digital images (< 0.05), namely: MSE (0.041), PSNR (0.041), PIQE score (0.012), meaning that there is a difference in digital image quality between IP FCR ST and HR, while with subjective analysis the respondents gave IP FCR HR results of 57.14% and IP FCR ST 42.86%. The difference in the results of the two types shows that IP FCR HR can be used as the main alternative in selecting IP FCR in intraoral dental radiographic examinations).

Abstract

Background: Radiation protection is very important for patient and personnel safety in radiology services. It has been given in the college through classical lectures, including in Radiodiagnostic and Radiotherapy Department Poltekkes Kemenkes Semarang. The student’s knowledge is routinely evaluated but their compliance in the clinical activities has never been specifically observed. This study aims to find out the relationship between knowledge toward compliance of the application of radiation protection on clinical practice students.Methods: This is quantitative research with a cross-sectional design. Research was conducted on 90 second-year clinical internship students of the Radiodiagnostic and Radiotherapy Department. The level of knowledge was measured by written test, while the level of compliance was observed by clinical observation. The affecting factors are investigated through indepth interview. Data were analyzed by Spearman Rank Correlation.Results: The knowledge levels among the students were "excellent” (18%), "good" (68%), and "fair" (14%). The radiation protection compliance levels were "good" (73%) and "very good" (27%). There was a significant relationship between radiation protection knowledge level toward radiation protection compliance (p value <0.05). The strength of the relationship was low (coefficient interval = 0.257). Conclusions: There was a relationship between knowledge and the level of compliance, but it was not the only influencing factor. The environment tends to have an effect on the level of compliance. Radiographers and clinical instructors should be good role model in applying radiation protection.

Abstract

Background: CT Coronary Angiography (CTCA) is a non-invasive imaging modality with a high spatial and temporal resolution to diagnose coronary vascular disease. FBP (Filtered Back Projection) has limitations in improving the image quality, so iterative reconstruction is used on CTCA. Adaptive Iterative Dose Reduction (AIDR 3D) is one of the iterative reconstructions developed by Toshiba, which has three levels of strength: mild, standard, and strong. The study aimed to explain the application of AIDR 3D in improving image quality on coronary CT angiography examination. Methods: This research is descriptive with a literature study approach, using articles from NCBI, Science Direct, and Google Scholar. The keywords used are CT Coronary Angiography, AIDR 3D, and Image Quality. The articles obtained are reduced based on inclusion and exclusion criteria so that seven relevant articles are conducted for extraction.Results: The results showed that AIDR 3D could improve the quality of CTCA images with the most significant percentage in AIDR 3D strong by reducing noise 18-46.1% and increasing SNR 21-84.7% and CNR 21-82.2%.Conclusions: The application of AIDR 3D strong in obese patients with CTCA is good to use with standard kVp and 250-450 mA without increasing mA so that it does not increase the dose. AIDR 3D strong can also be used in patients with normal body mass with tube current adjusted according to the patient's body mass if there is no indication on the right coronary artery. AIDR 3D standard can be used in overweight patients and normal body mass.

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.
