Dear experts,
I have a dataset of paediatric MRI and PET scans (1-18y) and I am keen to create a paediatric template to be used as a reference of normalisation of the scans.
I am writing to confirm that the following steps are correct: Do I need to segment the MRI scans and use the GM maps in the Estimate regression parameters module of SPM8? Having obtained the .TOM file I just need to run the second module (Create template). Is this correct?
Additionally, I am wondering whether it would be better to split the scans in different age ranges (I am assuming I will create an average paediatric template across 1-18 years old following the above stated methodology). My main concern is that I would like to create PET templates based on the MRI one, hence the metabolism is very different across ages.
Thank you very much,
Kind regards,
Bianca
