Abstract

Optimization of image quality in Cardiac CT Angiography (CCTA) is important for accurate evaluation of the right coronary artery (RCA). This study evaluates the effects of Adaptive Statistical Iterative Reconstruction (ASIR) and Temporal Resolution Enhancement on the image quality of the RCA sistole phase using the helical segment snapshot method. The study involved 10 patients with 40% ASIR reconstruction, 70% ASIR and 70% ASIR + Temporal Resolution Enhancement. Quantitative analysis showed that increasing ASIR levels significantly reduced noise and increased Signal-to-Noise Ratio (SNR). However, the sharpness of ASIR image is 40% higher than ASIR 70% (p < 0.05). The addition of Temporal Resolution Enhancement significantly increased the sharpness of ASIR images by 70% (mean score 4.4; p < 0.05). In conclusion, Temporal Resolution Enhancement effectively optimizes the quality of RCA images in the systole phase, supporting its use in CCTA techniques.

Abstract

The development of information technology in radiology, especially with the implementation of the Picture Archiving and Communication System (PACS), has brought significant changes in the workflow of medical imaging. This study uses a descriptive qualitative research design to analyze the impact of PACS implementation on workflow efficiency in the Radiology department of Wahidin Sudirohusodo Hospital Makassar. The results showed that the implementation of PACS impacted five main variables: Time Efficiency, Data Input Errors, Data Accessibility and Use, Job Satisfaction, and Filmless Reduction, which was analyzed using a p-value statistical test with a significance value of <0.05. From these results, it can be concluded that the implementation of the system provides improvements in various aspects measured, especially efficiency, accuracy, accessibility, and satisfaction.

Abstract

Quality control (QC) of Magnetic Resonance Imaging (MRI) equipment is a very important thing that must be done to ensure the continuity and accuracy of diagnostic images. The lack of MRI QC equipment, according to the American College Of Radiology (ACR) standards, is an obstacle to the implementation of strengthening the internal quality of MRI equipment. Objective: to provide an alternative solution for enhancing the internal quality of MRI equipment by creating a Signal To Noise Ratio (SNR) calibration curve. The research method is experimental and has two stages. The first stage of image acquisition is determining the structure of phantom materials with values of T1 (longitudinal relaxation time), T2 (transverse relaxation time), and proton density. This value creates a calibration curve of Time Repetition (TR) and Time Echo (TE) variations on the MRI signal value. The second stage is to create an MRI image acquisition curve with variations in TR and TE values to MRI signal values. Through exponential regression analysis, Compare calibration curves, shape, and correlation. Results: The calibration curve of the variation of the TR value to the MRI signal value follows the exponential regression equation y = 32.283e0.0007x with a correlation of R² = 0.5278, and the variation of the TE value results in an exponential regression equation y = 63.455e-0.01x with a correlation value of R² = 0.76. The results of MRI images with the exact parameters of the resulting curve follow the exponential equation y = 170.74e0.0011x with a correlation of R² = 0.418. In contrast, the variation of the TE value results in an exponential regression equation y = 1652.1e-0.004x with a correlation of R² = 0.6756. The ratio of the correlation value of the curve of the MRI image with the calibration curve of TR value variation is 80.76% and TE variation 89.01%; the noise value of TR and TE variation produces an average value of 9.5 and 9.9. The T-test of 2 samples produced a value of P=0.13, meaning there was no difference in the noise value produced. Conclusion: Measurement of SNR value can be an alternative solution for strengthening the internal quality of MRI equipment even though the hospital does not own the ACR phantom

Abstract

Radiodiagnostic and interventional radiology services (RIR) is one of the services that has a high risk to patient safety, one of the risks that exist in RIR services is the use of iodine-based contrast materials with a large volume that can increase the occurrence of CIN (Contrast Induced Nepropathy), CT scan of the abdomen with contrast also has a potential risk of radiation exposure received by the patient. Efforts need to be made to improve new protocol standards that prioritize patient safety. The research method was carried out by an experimental method followed by the implementation of the new standard protocol CT Abdominal Scan using contrast by involving 10 samples, both CT Scan Abdominal Examination in contrast to the old standard and with the new standard. The results of experimental research using phantom materials show that the use of low volume contrast and low radiation dose produces a higher enhancement or opacity (HU) value when compared to using low contrast volume and high radiation dose. The results of the protocol implementation of 10 samples evaluated by 2 observers showed that there was no difference in the value of anatomical images between the old and new protocols. Anova's one-way analysis showed that the value of F-value = 0.22 and p-value = 0.88 because the p-value was greater than 0.05, there was no significant difference between the two CT Scan protocols. The results of experiments with phantom and the implementation of new standards using contrast volume and low radiation dose have proven to be an alternative to the new protocol standard CT Abdominal Contrast Scan based on patient safety.
