The (left?) IJV looks much smaller to my completely untrained eye. Is that just a normal one side dominant thing like being right handed?
Thanks for putting up all these pics in these different threads Mark, very interesting stuff. Do you have any posted of a non-ms'er system? I'm just wondering what a normal one would look like?
ETA: Ok, so I played around in photoshop a bit so that I could ask you some questions about these Mark. Hope you and Leetz don't mind.
I can't remember what setting I clicked to get all that shading, but that's how photoshop sees it. The one thing I can't get over after looking at it for a while is the lack of symetry. Are all MRI/MRV images like this? I'm thinking that maybe if there were other slices that were taken closer and further from the origin you might see more symetry in them. So anyways, my questions:
The triangular area: Why does it look so different? Is it simply not going to look the symetrical to the other side because of the angle or depth at which the picture was taken? Sort of like what I was saying above?
What veins are the two in the middle?
I'm guessing that this picture was taken looking at Leetz's face. So right would be left and left would be right?
With that in mind her left IJV looks much thinner than the right. The left also has the triangular area which almost seems swollen in these pics, but that could be explained away by my questions above about slices and angles that the pictures were taken at.
Ok, I was playing around again to figure out how I did that last picture. I used the magic wand to highlight the veins and then made a new layer. Then I replaced the colour on the layer to whatever photoshop had it defaulted too. I guess it was black because that's how all the shading came about. I really have no idea how photoshop does any of that, I'm really just messing around here. Here's another view with more of the veins selected:
