We are happy to announce that the Positron emission tomography BIDS extension 
is finally nearing it’s completion. Hence, we are seeking final community 
feedback for the PET BIDS standard. We are looking for feedback on GitHub and 
specifically to the BIDS-PET extension proposal (

 ). We have also developed an extension for the validator (

 ) and added PET examples into BIDS examples (

 ). The community review will close on Friday (Feb. 12) at 11:59pm PT (pacific 
time).



This BIDS extension seeks to establish how PET data and additional metadata are 
organized within the BIDS structure. This encompasses the recent guidelines for 
brain PET data in publications and in archives provided in the consensus paper 
(Knudsen et al. 2020, 
https://secure-web.cisco.com/1MIWMgeigCAuC-K3Vo4dwvsJCklRfo3-nj_Avatf4FkWMOawTcPrfz1RKd1svX27cs-AjgpYIDrT63jb2G-muHjpKjiTvRq9d8jWYqnymru7rWxU5AnEJzNmanBs13iOBNazfJMm7u0fn_KnB_piCvSUWv9DSw07hQ1VhtnH5lPDgItXKmYx0u8LSm-OdWkWVHpKlfVgfEY4E78qT2J21Y5k2IQIJavfMCucEhWg6ptZjsvh6WR1x-vABTj3nhSI7YMXArof-rba5j3Zuzlj6yQ/https%3A%2F%2Fjournals.sagepub.com%2Fdoi%2F10.1177%2F0271678X20905433
 ), including blood and metabolite data.



The final review entails a two week period for public commenting, with a 
possibility of extension for unresolved discussion. Once public comments are 
concluded, there will be a one week freeze, during which only critical issues 
will be considered. (Please see our release protocol for more details,

We are looking forward to hearing from you,
