• NL Standardization Protocol for Quantitative FDG-PET in multi-Center Trials - Dr Ronald Boellaard

The Netherlands Standardization Protocol for Quantitative FDG-PET in Multi-center Trials (English translation of Version 1)

Please keep the following in mind:

The development of this protocol was started about 2005 and approved more than 1 year ago in The Netherlands (NL). However, with gained insight, changes are scheduled to be incorporated in the next version by 2010. The following changes will be made (consider them being applied already or underway):

• Use of oral contrast is now excluded but will be allowed in the next version
• We are currently working on standards for CT as well, including GL for doing CT-QC (in cooperation with the radiologists/radiology societies in NL)
• There will be an upper limit for dosage
• We are working on traceable/calibrated and mutually linked sources for both PET and the dose calibrator and these will be used for absolute (rather than cross-) calibration (but in addition to the cross-calibration using FDG).
• Reconstruction settings given in the protocol are indicative and are likely not applicable for future scanners and software upgrades. Therefore reconstruction parameters should be set such that they provide results that meet the specifications given for the multi-center QC experiments. Same settings should then be applied to patient studies (see also comments under "execptions/special features” and comments made in the paper by Boellaard et al. EJNMMI 2008).
• Various other minor edits/typos/changes

The protocol is not a step-by-step description of the logistics for doing a PET/CT study. However, it has been set up in a somewhat chronological order and may thus be used to populate (copy-paste) such a step-by-step description. Additional work required ... FDG-PET/CT Technical Committee input is highly appreciated.

Ideas for Profile version 2.0

A collection area for ideas to include in the next version of the Profile

A PET Physicist here had this feedback, which I think you will appreciate:

I wish there was a way to accentuate the difference between dose and activity. There is an important distinction with proper definitions. Activity is a measure of decay rate, dps, mCi, MBq, whatever units one prefers. Dose is a measure of energy deposits in matter. A complex phenomena measured in rem, Sv, whatever.
