Abstract

PET/CT has become an important cancer imaging tool for both diagnosis and staging. One of the most important values for both diagnosis and staging is Standardized Uptake Value (SUV). However the data accessibility and analysis would be limited because the SUV is usually retrieved by using their own application software only. In order to eradicate these limitations, a novel SUV calculation scheme based on the data from DICOM files was created. This scheme was written by MATLAB which is widely used in science and engineer. For much more practicable, the scheme was tasted a performance by comparing with Xeleris workstation, the well-known application from GE healthcare. The comparative analysis of both systems was done on 108 slices of DICOM files were obtained from 11 patients (8 men, 3 women). 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. The results of performance reassure an advanced practical use of the new scheme. The interchangeability of this scheme offers user convenience and approachability of data and is a stand-alone application that allows more accessibility. Physicians can interpret PET/CT scans without further applications of other software.
