For those who are curious how Dr. Zamboni is now measuring CCSVI, as he discussed in Matt Embry's video, below is the scientific explanation of his video clip technology.
"Dr. Zamboni's work with the International Space Station has helped him refine a new, operator independent means of measuring venous flow. He admitted that a major problem and a cause of controversy in CCSVI diagnostics has been the fact that using ultrasound as a diagnostic tool is completey dependent on the training of the operator. And this has been confusing and has kept the science from moving forward. The main difficulty is that the jugular vein is a pulsatile (or moving and pulsing) vessel, and it has different measurements during the cardiac cycle, depending on how much blood is going through at any one time. Also, the jugular vein is ellyptical, and not a circle, which has also confused cross sectional (CSA) measurement.
His new method of measurement looks at flow velocity and how the jugular venous pulse (JVP) is synchronized with the carotid artery and heartbeat. By looking at normal subjects, we can see how all three of these measurements are synchronized in a determinate interval of time. The venous pulse begins with the heart contraction, giving a positive wave up to the brain. Each movement of the heart is reflected in the jugular vein.
Dr. Zamboni trained astronauts in how to use B mode ultrasound to take video clips of their venous return and JVP on the space station. These video clips are purely data, which were then transmitted to vascular researchers to extrapolate the hemodynamics of flow. The beauty of this new video clip method is that it's just numbers...like an EKG readout. You can't give a neurological "opinion" on numbers. It is, or it isn't, normal. Dr. Zamboni is already seeing that the distance of waves is much wider and more regular in normals, than in patients with CCSVI. This new non-invasive method will give us a precise picture of the heart-brain axis, and help end the diagnostic controversy of CCSVI. It will also help clarify who should be looked at further with venogram, and can be used as a follow-up method for patients after venoplasty treatment."
I hope this pans out. A more precise measurement, bypassing neurologist's opinions for precise quantitative measurements, and a means of follow-up method for patients after treatment...all good!!
