The somewhat bizarre story of my cerebral angiography

[Jules]

I’ve just commented on another discussion with info that JustBreathe, who knows loads about jugular compression & testing posted:

Jugular ultrasound

Natty, Here is a bit more information to start. Velocity of greater than 50 are considered abnormal. Diameter readings are usually compared from the jugular foramen, C1, and a few points below to the omohyoid muscle looking for stenosis. There is little evidence describing normal active data. Keep in mind that this testing is very limited for a few reasons: it can vary greatly depending on the sonographer’s technique and pressure applied to the probe more importantly the readings are taken …

There’s a few discussions going on at the moment about jugular compression, so the link might be helpful- JustBreathe gave info about how the ultrasound test results may be limited.
