From the patient answer to the reader written in Russia, we can see dr. Weinberg is really patient and kind. It is lucky to have an opportunity to work with him as resident or fellows.
Hi there I hope you are well. Please may I ask you a question. If there is an aneurysm in a condylar vein should that be reported or is it ignored by radiologists? Thanks
Рассматривать КТ и МРТ снимки конечно можно и нужно , но имея возможность делать 3д построения , лучше пользоваться для оценки именно 3д . Да и шире пользоваться возможностью контрастирования , для более чёткого выдиления показываемых патологий .
My apologies because I am relying on a computer translation of this comment, but yes, I agree with you, 3D reconstructions are a valuable adjunct tool to assess these vascular pathologies. For me, it's usually not the primary review tool, but I do use them a lot.

@@sergeyshchurko9541 No problem for you writing in Russian, but I have to translate so hopefully the meaning is close. Yes, I definitely agree that scanning in certain position leads to differences in imaging. For arterial imaging, it probably doesn't make much difference. For venous imaging, the venous outflow of the head is significantly different laying down versus standing up. For disc in the spine, it is a HUGE difference. What may look like a small disc protrusion may be much bigger when loaded. Unfortunately, we don't have a lot of tools to deal with this. There are some MRIs that scan in the standing position, but they are prone to motion and usually lower quality magnets.

@@sergeyshchurko9541 Thanks for the explanation. That makes sense. I think it is even more important outside the brain, where venous pressures change much more with position.
Hi there please can you help me . I recently had a CT angiogram of head and neck with contrast but the report says everything is normal , it only mentions the arteries there is no mention whatsoever of the veins . I’ve been doing a lot of research and it looks like the right internal jugular vein is being compressed at the C1 vertebrae level really quite badly but there is absolutely no mention of this on the report. Why do you think this may be ?
CT angiograms are really designed to look at arteries and not veins, although you can often see veins well. It is very unusual to have any meaningful narrowing or occlusion of the jugular veins in the neck if you don't have cancer or infection that you already know about. I doubt any further investigation is warranted but you can talk about it with your doctor.
Thanks so much for the reply I really appreciate it . I have a connective tissue disorder and have been diagnosed with Atlanto axial instability, I have heard that if there is a stenosis of internal jugular vein it’s usually at the C1 level , as you say it’s not very common to have it but do you think that’s why it might be easily missed by radiologists
Sorry for more questions but can I also ask this . I understand that CT angiograms are done to mainly look at arteries but if a radiologist could see a significant narrowing of a vein would they normally report it or completely ignore it ?
Yeah this hinges on what people think is significant. Anything short of a clot sitting in the vessel or major extrinsic compression, people won't mention. The reason for that is because it doesn't usually mean anything. People have been blaming venous narrowing for all sorts of ills for decades and nothing has panned out, except maybe elevated intracranial pressure.
I follow up your lectures, thumb them up. Persistent effort to upload free, high quality lectures is really not easy. Thank you so much.

awesome lecture
thank you so much. I was struggling with how to read cta head and neck for 1 year, you have dome amazing job.
Glad it was helpful!
thank you , that is very informative and helpful
Please use maximal pointers and image sizes when possible. Some of us are old. Thank you.
That's a great idea! I'll try to pay more attention to that in the future!
Many thanks
You are welcome
Nice 👍
Thanks for the visit
Great!
Thanks for checking out the videos. Hope you enjoy the rest of the channel and website!
tnx .. great like always
Thanks again! Always great to see you on the channel!

That's usually not something important. Veins can often have little outpouchings or variations that are not really very significant in most cases.
Thank you so much , I really do appreciate it.

I can’t thank you enough for replying, you have provided great insight . I hope the doctors can get to the bottom of my problems .
