QIBA FDG-PET/CT Standardized Uptake Value (SUV) Technical Subcommittee

The objective of this subcommittee is to define how to calculate SUV in a consistent manner regardless of manufacturer, model and version of scanner and workstation.

Completed:

Collected DICOM PET/CT images of the same reference phantom from scanners from GE, Philips, Siemens
Image data collated and compared to DICOM header information
Collected answers from vendors to questionnaires along with other submitted SUV calculation documents
Described generalized SUV calculation method with vendor-specific variants

The previously described objective of building a common reference DICOM test image that can be generated by each scanner and read on PET DICOM display stations to check information fidelity is the subject of the separate University of Washington Digital Reference Object (DRO) project (described in the 12-Month Final Project Report).

SUV Calculation

Vendor-neutral pseudo-code for SUV calculation - updated 20170920 to correct swapped Rescale Slope/Intercept; updated 20180626 to correct DECY term and incorporate start datetime rather than just time
Vendor-neutral pseudo-code for SUV calculation - extracted "happy path only" - for clarity (BQML, no private data elements required, series time is OK) - updated 20170920 to correct swapped Rescale Slope/Intercept; updated 20180626 to correct DECY term and incorporate start datetime rather than just time
