I saw that the correction of partial volume effects can be used to create the maps (Shafee, Buckner & Fischl, 2015)*. Can I use the PVC functions of PetSurfer for this purpose? And in case I can: Should I apply PVC only on T1? Or also in T2? Which T1 should I use? The original T1 or the T1 with corrections (for example, the nu.mgz file that is corrected for variations in intensity)? Any other advice for calculating myelin maps would be welcome. Thank you in advance, Marina *Link: MailScanner has detected a possible fraud attempt from "secure-web.cisco.com" claiming to be https://secure-web.cisco.com/1u63hhRf89DUCFEbAiJgcglonczMMzDanUvnXz0DR2W2P39ddbeTTd8zOdP-ChfOveA6XCFA9OL0oSXezE1e96Zfb3KxYR2LDlW-jMoaOoDyQzXJ1Go8H55H3p9wb-PUnVAgkSARhLETfdcQE1Jy3gqRrJtBfJp0CHVh3heFHtl4qp4F98--n6sY0supjb4IKVTOS7yXscz0-PWIge3FA_BDxgUHKOMICIqgiNYDKcVpC3Hr1WYj-GctL7TMtCW-fB7qAj4t3Gaf-ErOb_DKx5g/https%3A%2F%2Fwww.ncbi.nlm.nih.gov%2Fpmc%2Farticles%2FPMC4262571%2F%23R48<https://secure-web.cisco.com/1JlAz9aQioBCdg379E7idALB4EltLyOBrORvLMLOKKAfsOZ5T86whDDL8Q-4ZOYG7rMgwoBYIyC4d5BsThH9nR2UT-_82NU3WKyCZrii6txF4QxCWh-K6Hy6aC2vsOwRupJhTnA_Menjtq1hXOSwjndsWxN3BBnw625eBs0OgB8t1ZM0uY7sLR_VuAuMcsvNsQQ9qofNHMaLp6aidYJh3yhta2kwGeWzCXmtyE1XOS-Z2uiDZa5gqmp9A0egHtAOC68aEN1v8l0S-ikEhif20Qg/https%3A%2F%2Fwww.ncbi.nlm.nih.gov%2Fpmc%2Farticles%2FPMC4262571%2F%23R48> ________________________________ The materials in this message are private and may contain Protected Healthcare Information or other information of a sensitive nature.
