BET settings
by Chris Racey 13 Sep '10

13 Sep '10

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

YNiC seminar 16th September
by rem 13 Sep '10

13 Sep '10

Dear Users This week (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.

Early onset?
by Philip Quinlan 27 Aug '10

27 Aug '10

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 29 Jul '10

29 Jul '10

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 27 Jul '10

27 Jul '10

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

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

Important issue about scanning
by Gary Green 14 Jul '10

14 Jul '10

Dear Users At this time of year it can be hard to recruit participants. It is therefore very tempting to recruit close friends and relatives. One of the ethical issues that arises from taking this route for recruitment is that it might be difficult for a friend or relative to turn down your request. Unfortunately, if they accept then it then places you and us in a rather difficult position if an anomaly is spotted on the scan. This is extremely difficult to deal with if the investigator is in the control room when the anomaly is detected. We already have a policy that prevents staff from scanning relatives. We now will extend this to the scanning of all close relatives. I hope that you can understand the reasons behind this decision. The radiographers have been asked to, politely, refuse to scan relatives of investigators.

Dear Users Today (4 pm in YNiC) there will be a talk by Lee Harrison from YNiC. The title of Lee's talk is "Bayesian Inference in Neuroimaging". Abstract: "Analyzing data involves quantifying the uncertainties inherent in their production, e.g. measurement noise. A way to achieve this is to formulate models in terms of probabilities, in other words, Bayesian models. A Bayesian approach provides a language to formally represent such uncertainty and the tools necessary to manipulate these notions in a coherent manner. The aim of this talk is to give an overview of some of the ideas and rhetoric used in constructing Bayesian models, estimating them and applying them to neuroimaging problems. The talk is based on an introduction to Bayesian inference given at the Statistical Parametric Mapping (SPM) short course. The emphasis will be on applications and not the equations. For example, using Dynamic Causal Models (DCM) to ask questions about interactions between cortical regions and spatial models to implement a computational model of how an observer represents uncertainty in a sequence of events."
