I am far from knowledgeable on this subject, however, my stab in the dark, with my eyes closed, is that the MR machine has a setting for what minimum diameter of vein to image, and below which size to ignore. I guess they used a standard setting, with the sensitivity turned all the way up, and hence the "cloudy" appearance because all the superficial veins were also imaged. Dr Dake knows he is looking at the larger veins, and so sets this control appropriately, where my guys used their standard settings. And if you forgot how this paragraph started, I don't know what I am talking about.cheerleader wrote:your pics look like the superficial/facial veins....Jeff's looked like the pics Marie linked to

I think they were focused (for the little area they did) deep enough, as all the veins appear in the image (from all depths), my guess is that they just had the sensitivity turned up to high in the part of the computer system that interprets what comes back from the scanner, into an image. After reading the first few posts, I took to the images with a photo manipulation software, and if you alter the brightness and contrast of the image, it heads towards the "expected image'.PeekaBoo wrote:my thoughts exactly...maybe a higher strength 7 tesla?
ohh, stop, I'd blush, but it may affect my next scan. I have to admit, I keep looking at these images, I mean, its not like its my reflection in a pool of water.Cheerleader wrote:Cure, you handsome devil!

On yours the jugs a look almost like a shadow instead of lighted up big and clear? I will be interested to hear What Dr D says about it
DR Dake wrote:...Unfortunately, the study itself is somewhat noisy with a lot of arterial overlap that obscures resolution of the venous anatomy. I looked at every image of every sequence and I can say that the left sided venous drainage is asymmetrically diminutive compared to the right. It is difficult to pinpoint focal severe lesions rather it is more diffuse in nature. Bottom line, before doing anything else I would proceed to have a CT venogram from the aortic root up to the top of the head. This will clearly delineate the venous anatomy. It is much more operator independent that MR, but it does involve some radiation....
