Feedback from Research Groups in February 2008
Memory and Knowledge (12 February 2008)
Sensitivity artefacts in MRI
- Combined spin echo and gradient echo images does not yield improvements in areas subject to sensitivity artefacts. Request for a tool to provide parameters for a sequence optimized for imaging a specific area.
Action: ChristianSchwarzbauer will talk to RikHenson about this.
Source control for software development
Action: MatthewBrett will give a Methods Group talk on Code Version Control on 14 February (see MethodsGroupMeeetings).
Imaging with patients
Advice on best practice in co-registration of brains with lesions: relative merits of manual masking of areas of lesion versus SPM5's default method.
Action: MatthewBrett will talk to KaralynPatterson about this.
Query about coregistration with MEG, and the use of MRI of lesioned brains to constrain MEG source solutions. Highlighing difficulty for SPM or MNE if there is a lesioned area on the cortical surface.
Action: None at present as MEG is outside the Methods Group's current range of expertise.
Methods Group's role in MEG development
Action: None at present as MEG is outside the Methods Group's current range of expertise. However noted that OlafHauk and OlegKorzyukov are active in expanding this expertise, and will look into case for expanding resources in this direction. Methods Group meetings will continue to provide a forum for sharing of experience and developing understanding.
