- W2356974448 abstract "Purpose: Gemstone spectral imaging(GSI) has the ability to generate material decomposition(MD) images for separating materials and analyzing the content of special materials.The purpose of this study was to evaluate the confidence and accuracy of GSI in analyzing the content of iodine.Methods: Iodine solution with varying iodine concentrations(mg/ml) were dissolved in distilled water into 18 different groups in 50ml tubes.GSI scans were acquired on a Discovery CT750 HD scanner with a small field of view(FOV,25cm) and thin slices(0.625mm).Tube rotation speed was 0.6s / circle,0.8s / circle and 1.0s/circle respectively.Image processing was performed on GSI Viewer browser to measure the iodine content of the solution.Pearson's correlation analysis and paired t test methods were used for statistical analysis.Results:Positive correlation was found between the iodine concentrations and the reference-standard density of iodine(r=0.999,P=0.000 were found in every group).There was no significant difference between the measurements and the true value of iodine content in every group(P0.05). Conclusions: GSI mode can generate MD images for analyzing the material contents,GSI mode can accurately reflect the content of iodine in different concentrations and be used for quantitative analysis." @default.
