Cortical veins under 7 tesla MRI

It seems that they are able to detect oxygen percentages and to use it as biomarker.

Quantitative oxygen extraction fraction from 7-Tesla MRI phase: reproducibility and application in multiple sclerosis.

Abstract
Quantitative oxygen extraction fraction (OEF) in cortical veins was studied in patients with multiple sclerosis (MS) and healthy subjects via magnetic resonance imaging (MRI) phase images at 7 Tesla (7 T).

Flow-compensated, three-dimensional gradient-echo scans were acquired ...

% definition of technical failure of vein angioplasty

http://www.sciencedirect.com/science/ar ... 140602297X

Primary patency was defined as a patent central vein without recurrent stenosis or the need for further intervention within the central veins. Assisted primary patency was defined as a patent central vein that underwent further intervention to improve patency. Loss of patency was defined according to accepted reporting standards.

Technical failure was defined as <50% gain in luminal diameter. Early failure was defined as an inability ...

Questions - help!

Do any of you feel a pain in the front or sides of your neck? What the heck is that?!


Have you ever noticed that your symptoms are posture related? Any time I have to lean forward, especially w/arms out, symptoms flare afterward. This is: driving, pushing stroller, working on computer. What does this mean???

Flow & anatomical abnormalities in MS vs Controls using MRI

Hello everyone,

I am delighted to present this work fresh off the presses. Within the paper lies clear differences in venous anatomy in the MS and HC samples, but most importantly in jugular flow between the two. Also elucidated are the pitfalls of the Rodger and Traboulsee studies. Specifically, using individual IJV flow and percent stenosis method, instead of total IJV (and normalized IJV flow to arterial flow) and using fixed area for determining stenosis. ...

Muscle compression?

Hi--

If one is found to have IVJ compressed by sternocleidomastoid or some other muscle, then what??? Is there a procedure to divide this muscle? Should be.

Crowdfunding.

This article speaks about groups of patients that have succesfully managed to set up a clinical trial via crowdfunding.

Interestingly, they did it for MS.

Maybe it could be a possibility for us to do it for CCSVI

Researchgate

Researchgate: it sounds like a Watergate scandal, but it was described to me as "Facebook for scientists"

Accounts are free & scientists put the full text of their research articles on their pages.

http://www.researchgate.net/publication ... CSVI_in_MS

Clicking the above link and choosing "join for free" gets you in, but they want it to be scientists only (sigh) and so you need a department, institution, and institutional email.

CCSVI and cancer

http://www.sciencedaily.com/releases/2012/06/120621113329.htm

Seems to uneducated me:
One of the known features of CCSVI (not saying anything about "MS") is the presence of many collateral veins. The reason for these, as discovered in studies concerning flow rates in collateral and jugular veins, is likely to be the presence of a stenosis, with resulting hypoxia, and the generation of replacement venous capacity to replace what was lost to the stenosis.

I have my own opinion that the collateral ...
