The prognostic significant parameter for PET scan is Standard Uptake Values (SUV). The SUV can be used as a tool to supplement the visual interpretation for physician. However the SUV can not be calculated without the vendor's application software. In order to calculate the SUV without the vendor's application software, a new standard uptake values (SUV) calculation scheme based on image intensity has been introduced. This new scheme is tested by using 108 slices of DICOM files obtained from 11 patients (8 men, 3 women). The comparative study between this scheme and the GE Xeleris workstation has been done and the results showed that the correlation between the two systems is statistically significant with a 99% confidence interval. The average percentage of accuracy is 85% for the report at a 95% confidence interval. So this scheme can be used as an alternative tool to calculate the SUV and it can be installed in any computers.Mahidol UniversityComputer ScienceMathematicsArticleSCOPUS
