Abstract
One of the drawbacks of the 32 slice CT-Scan is that it has not optimally reduced streaking artifacts on abdominal non-contrast media images. Spatial filter based on computer programming is one solution to reduce streaking artifacts on CT-Scan images to improve the quality of CT-Scan images.
Objective
To examine the application optimization using the Spatial filter method based on computer programming on CT images of Non-Contrast Abdomen Media by searching for SNR, CNR, and anatomic information after artifact reduction.
Method
This type of research is a quasi-experiment with a pre-post test only without control group design. The research samples were 17 Abdomen slice thickness CT images 5 mm and 10 mm with purposive sampling. Quantitative measurements of SNR and CNR by analysis using the Shapiro Wilk test, followed by using the Wilcoxon test. Assessment of anatomical information was carried out qualitatively by 2 radiologists, analysis with the Kappa test and continued with Mann Whitney.
Results
There were differences in SNR (p-value <0.001), CNR (p-value <0.001) and anatomical information (p-value <0.001) after the application of the Spatial filter method based on computer programming.
Conclusion
The use of computer programming-based spatial filter method for CT-Scan 32 slice can be used to reduce the reduction of streaking artifacts
