Purpose:Facilities use own sever or mini PACS system for storage and analysis of the PET/CT data. Mini PACS
can storage scan data as well as measuring SUV. Therefore, the study was performed to confirm whether or not
measured SUV on mini PACS is measured equally on PET/CT workstation.
Materials and Methods: In February 2011, 30 patients who were performed 18F-FDG wholebody PET/CT scan in Biograph 16, Biograph 40 and Discovery Ste 8 were enrolled. First, using each workstation, SUV in liver and aorta of mediastinum level was measured. Second, using mini PACS, SUV was measured by same method.
Results:The correlation coefficient of SUV in liver between PET/CT scanner and min PACS in Biograph 16, Biograph 40, Discovery Ste 8 was 0.99, 0.98, 0.64 respectably, the correlation coefficient of SUV in aorta was 0.98, 0.98, 0.66, and these were showed positive correlation coefficient. Difference of SUV between Biograph workstation and mini PACS was not showed statistical significant difference at 5% level of significance. Difference of SUV between Discovery Ste 8 workstation and mini PACS was showed statistical significant difference at 5% level of significance.
Conclusion:In case that patient was scanned by the other scanner, if the correction of SUV formula in mini
PACS for each scanners is performed, mini PACS will be usefully used to provide consistently quantitative
assessment.
