YNiC seminar today

by Rebecca E Millman

Dear Users Today (4-5 pm YNiC open plan) Miriam Johnson from the Hull York Medical School will give a talk on "Magnetoencephalography appearances in breathless patients with and without air flow directed to the face." Everyone is welcome to attend. Best wishes Rebecca Background: Intractable breathlessness is a common and devastating consequence of many diseases. Breathlessness affects all aspects of life, causing major distress for both patient and caregiver. Many patients face psychological, social and physical repercussions of persistent breathlessness, which require, long-term NHS support especially out of hours. Research into possible mechanisms for the perception of breathlessness has largely concentrated on peripheral pathways. However there is a growing interest in functional brain imaging using positron electron tomography scanning and functional MRI (fMRI), mainly in induced breathlessness in healthy volunteers. Similarities with pain perception are striking. However, little is known of these processes in patients with chronic breathlessness due to lung disease, indeed, one study suggests that patients with asthma demonstrate habituation and down-regulation of perceived unpleasantness due to breathlessness. Moreover we know nothing of the effect of interventions to improve breathlessness; patients with chronic breathlessness tolerate fMRI poorly. Magnetoencephalography (MEG) scanning is a possibly tolerated method but has not been tried. There is some clinical evidence that the use of a handheld fan reduces the sensation of breathlessness and may reduce the need for nebulisers and oxygen. The fan directs airflow to the area innervated by the 2nd and 3rd branches of the trigeminal nerve. It is universally available, cheap, non-invasive and easy to use in any setting alongside any other breathlessness intervention with no contra-indications. As the cost to the NHS of oxygen, nebulisers and inhalers and hospital admission are considerable, this area warrants research both with regard to clinical effect but also to mechanism of action. -- Dr. Rebecca E.

Re: BET settings

by Chris Racey

I ran 3 identical first level FSL analyses of a localiser scan in order to compare the different bet settings (applied to all structural and functional images). I can confirm that BET with the recursive flag (-R) produces the best outcomes with higher Z values when transformed to standard space. The -B option looks good when examining the resulting BET images, and deals nicely with residual neck artefacts, but actually produces worse results at the level of the statistics. Below are images showing zstats from each first level analysis (face-place localiser), converted to standard space and displayed on the MNI brain. PPA (blue), FFA (orange), standard space - BET with no options http://i.imgur.com/q3FdX.png PPA (blue), FFA (orange), standard space - BET with -B option http://i.imgur.com/QC9al.png PPA (blue), FFA (orange), standard space - BET with recursive option (-R) http://i.imgur.com/Nqob1.png Activation is more extensive and more significant with the -R option. Images of the structural scans after each bet extraction can be seen in the album below http://laserdragon.imgur.com/brainimaging It seems that the standard pipeline involves using the -R option anyway, but I thought people might be interested to see the difference it makes, and that the -B option turns out to be pretty bad.

As Andre says, changing the starting co-ords can also help - for the record, the standard automatic cleanup for the structural scans currently uses -c 90 116 166 but doesn't use -R. I'm not entirely sure why it doesn't as I thought it did (and was about to say it did until I double checked). I'll probably change this to use -R by default (for the automatic ones) unless someone can remind me why it doesn't... Mark -- Mark Hymers York Neuroimaging Centre

Re: BET settings

by Andre Gouws

the -c option flag too can be useful and has virtually no cost .. this simple sets the centre of gravity to which the initial sphere is fitted. find the coordinates of the AC in your participant (slice numbers) set the -c flag to this and usually the initial extraction is vastly improved.

BET settings

by Chris Racey

Hi all, I was having some problems bet extracting some of my structural scans, I was getting a lot of left over neck that was screwing up the alignment. I noticed the current version of bet has a new option flag (to me at least), which focuses on cleaning up the neck. The option is -B . When using this flag the processing takes considerably longer, something along the lines of 10-15 mins per scan. However, not only did it resolve the issue, but the resulting image looks cleaner and more precise than I would expect from a normal bet. I've attached a comparison image so you can see the effect. I did similar comparisons running this flag with functional data and it also shows improvements. At the moment I'm re-processing my data files in this way before running my analysis. I thought I'd mention this in case it might be a useful option for other people to use, but also in case anyone knows any reason why it might be problematic. I'd be keen to know if anyone knows of any reason why I shouldn't use it? I notice the overall intensity seems slightly lower when this flag has been used, is this likely to be a problem? Cheers, Chris Racey

Early onset?

by Philip Quinlan

We recently carried out an MRI study and (to keep it simple) we compared two conditions A and B. We found two regions that preferred A to B, region 1 and 2, respectively. I was keen to explore the time series a little further. So what I did was take the A-B difference for each subject in each of the regions and compute the 95%CI for each 2 sec interval from the start of the stimulus presentation. We get a difference time series for each region and for each point we have a 95%CI. I have plotted the CIs for each point on each function (one for region 1 and one for region 2). Now I note at which time point the CIs reflect a sig diff (i.e., dont cross the x axis) and what I find is that the critical difference occurs earlier for region 1 than 2. At last a window on the time course of psychological functioning? I, of course, now want to claim my Nobel Prize but suspect this is completely flawed. Please advise. Philip. ******************************************************************** Philip Quinlan E-Mail: ptq1(a)york.ac.uk Department of Psychology FAX: (01904) 433181 The University of York Tel: (01904) 430000 Ext. 3135 Heslington Direct : (01904) 433135 York YO10 5DD U.K. ********************************************************************

Today in YNiC

by Gary Green

There is an additional seminar today At 2pm There will be a talk entitled "NMR and MRI sensitivity enhancement by Parahydrogen Induced Polarization" by Kerstin Münnemann Max Planck Institute for Polymer Research, Mainz, Germany Despite its wide applicability in chemistry, biology and medicine, Nuclear Magnetic Resonance (NMR) spectroscopy still suffers from its inherently low sensitivity. Exploiting the large signal enhancements associated with hyperpolarization techniques, such as Parahydrogen Induced Polarization (PHIP), however, NMR or MRI qualify for monitoring dynamic processes in real time. In this lecture, the synthesis and hyperpolarization of several biocompatible molecules like barbiturates, Vinylpyrrolinidon (blood plasma expander) or Dimethylcarboxylat (precursor to fumarate) will be presented. Polarization transfer to 13C in these molecules by using adequate pulse sequences is demonstrated. Moreover, constant NMR signal enhancement of 1H and 13C is shown using a continuous delivery of parahydrogen by hollow fiber membranes. This allows the acquisition of two-dimensional NMR experiments requiring multiple excitations with constant initial polarization. The membrane technique can be easily extended to produce a continuous flow of a hyperpolarized liquid as will be shown for MRI applications. All welcome

Matlab versions

by Mark Hymers

Hi, As I mentioned a while back, just before the start of next term (September 2010) we'll change the default Matlab version to R2010a (7.10). This is just a reminder that it would be helpful if people could quickly check that any extra toolboxes or scripts which they rely on still work under 7.10 and let me know of any problems they see. If we don't get any reports, we'll assume that it's all ok. R2009a (7.8) will still be available until September 2011 as shown at: https://www.ynic.york.ac.uk/doc/ITPages/FAQ/Misc/SupportedVersions#Matlab Thank you, Mark -- Mark Hymers York Neuroimaging Centre

Visitors to YNiC

by Sam Johnson

Hello all, Just to let people know there there are a couple of visits to YNiC this week that might have an impact on you. Tomorrow (Tuesday) between 1:30 and about 2:30, and Wednesday morning, between 10 and 11 there will be groups in open plan. Both groups are pretty small and won't be using the computers so hopefully it won't be too disruptive. There will however be presentations, so you may rather have a late lunch tomorrow and a prolonged coffee on Wednesday. Thanks, and apologies for any inconvenience, Sam
