This video is intended for non-radiologists. The focus is NOT imaging interpretation. Instead, high yield imaging related information is reviewed through clinical scenarios and review of associated imaging related considerations.
This video was extremely well-presented and informative as a non-radiologist. Thank you very much for the time and insight you've provided.
Great video. I'm a resident and this has been extremely helpful.
Amazing. Best video I've seen on CT imaging. Please keep up the good work, very helpful!
Excellent work. Concise, clear, and well presented.
This video was immensely helpful for a US tech trying to branch out. Thank you!
Extremely helpful & informative
Thank you very much, very informative.
Thank you very much, very informative
what a great video. Thank you
Very well presented ,thank you
Thanks you are life saver
"Different radiologists say different things about the same poo." -best line in this video
Great lecture
Boss video again!
quite useful, thx
As a logo of your site i suggest a ruder x ray :) thanks for your videos
Good
9:25 so losing gray white differentiation isn't that useful, if you can see that, that part of the brain is already dead, right? (cytotoxic edema happens right around cell death). Conversely, a hyperdense artery clot doesn't mean you have an infarction since the brain has redundant/collateral blood supply. So for ischemic stroke, CT diagnosis doesn't seem to provide much useful information in the moment.
10:48 CT perfusion scans have very high radiation doses, I wonder if that has anything to do with a 5% stroke rate within 48 hours of a transient ischemic attack which isn't really a serious problem except when considering that supposed stroke risk. radiation therapy cancer patients had a 70% higher stroke risk than surgery patients, a total of 8% had a stroke after radiation therapy.
Stroke After Radiation Therapy for Head and Neck Cancer: What Is the Risk? 2016
12:46 I found it interesting that arterial blood clots as in ischemic stroke come from ruptured arterial plaque, while venous clots such as in DVT and PE primarily are the result of surgery, or a state of hypercoagulability, per
Risk factors for venous and arterial thrombosis, 2011,
and so the risk factors are totally different: hyperlipidemia for arterial clots, surgery and hypercoagulability for venous.
25:09 how come d-dimer, which is residuals after a blood clot is degraded by fibrinolysis, is taken as a sign of PE, but not as a sign that the body is already taking care/removing the blood clot, by definition of d-dimer? It seems in that scenario, time only improves the status.
25:33 saddle PE is no more critical than any other PE. In a patient group studied the fewest deaths were actually in the saddle PE group, and no surgical interventions were tried.
Short term clinical outcome of acute saddle pulmonary embolism, 2003
It's pretty logical too: there's no way a clot could block a high flow area like the pulmonary artery, and obviously the patients still have blood flow otherwise the heart would have stopped.
Note that amongst all the scanning technologies, CT seems to be highest risk because of potentially large doses of radiation and especially and inexplicably, no standard protocol.
Is Computed Tomography Safe? 2010
"Finally, CT tech- nologists receive no consistent education about what doses are excessive and, in many U.S. states, are not certified."
Ok
Thank you, very informative.
