Thanks for writing, Miriam. You can tell there is an embolus because you see a "filling defect" in the pulmonary artery. This means that where you expect to see contrast filling the lumen of a pulmonary artery, you see clot (embolus) displacing contrast (filling defect). I hope this helps. dm
Yes. That is something we always are mindful of, and we do our best to optimize the imaging parameters to minimize the radiation. It is important that we remain very cautious in our use of x-rays, especially in CT. At the same time, we should balance this with an understanding that the radiation we use in radiology has a theoretical risk to patients, largely based on the extrapolation of data from atomic bombs dropped in Japan at the end of WWII, and the Chernobyl disaster in Russia.
Very good question. The IV contrast we administer goes into systemic veins, and therefore goes first to the Right Atrium and then the Right ventricle, and then to the pulmonary arteries. So, the pulm arteries will normally appear "white" (dense like contrast). If there is a blood clot, it produces a "filling defect", which is an object (blood clot) which prevents contrast opacified (dense) blood from opacifying that part of the lumen of the pulmonary artery. Does that help?
I hope more will be stressed towards hemodynamics. RV dysfunction, RV/LV size, IVC and hepatic veins. These things could potentially discriminate aggressive versus non-aggressive treatment. Still, a great and expertly done presentations. I think these cases were not shock cases.
Hi I'm a 38 yr old and I just had my 6th confirmed DVT and a third suspected PE. The information provided is very informative but I am afraid that as I get older I will be more at risk of not catching it in time. Where can one reach out to as a support group or organization. Would like to get more info please. Can anyone reach out please?
Thank you very much for having the time to make these great videos and your slow style is of paramount importance

I love how you take the time to identify all of the anatomy. Thanks for sharing this.
Just saw this. I am glad to hear that you are finding my videos useful.

my question is, how can you tell there is an embolism? is it because of the white patches?
very useful....tnx 4 ur kind efforts
Just saw this. Thanks for your support!
great explanation thank you!
Just saw this. I'm glad you found it useful.
my reply was not directed towards you but the person who 'wants to go get tested!'
too many clinicians practice cya vs logical diagnosing
I agree.
Fantastic
Scary such low survival rates makes me want to go get tested!
thank you
You are welcome!
I am glad you are finding my videos useful.
I AM lorning pulmonary angio how to plaining wer from to wer
I am so glad you find these videos useful.

radiation exposure can do more harm than good sometimes
Yes. Agree. We need to be more cautious about ordering CT scans.
plz sending immegs
this is very very very useful
Thanks very much. More to come.
