D-dimers, PE studies, and covid

By

I understand that it’s very common for a patient who tests positive for covid to have a high d-dimer value. The facility I’m currently working in orders CT PE studies on all of these patients. (I have yet to see a positive scan, but that’s besides the point.) My question is, is it reasonable to suspect a PE in a covid positive patient just because their d-dimer is elevated? Or am I correct in thinking that the elevated d-dimer stems from the covid infection but does not indicate an increased risk for PE?

Onetonline salary search change?

By
Did this change? I am having a hard time finding the same lists I saw 2 months ago. https://www.onetonline.org/link/summary/29-2034.00#AdditionalInformation https://www.onetonline.org/link/localwages/29-2034.00?st=OR&p=hourly I used to be able to see wage by area and sort it by state and see the differences per state and per city in every state. I can't seem to find this same list anymore. I can see a bell curve but I can't sort by state or wage or anything.

Question regarding ultrasound

By
Hello radiologists, I have a quick question regarding ultrasounds of the scrotum. (Not asking for medical advice just wondering about something). I’ve done an ultrasound of the scrotum and the radiologist only took pictures of the right side of the testicle and then the left side but not in between so my question is, do ultrasounds show all “angles” of a testicle or does the device need to be held at various areas to show a full testicle? Because if only one side of the testicle is seen then wouldn’t the other side be as important in diagnosing something? Thanks! submitted by /u/doomyboomy [link] [comments] source https://www.reddit.com/r/Radiology/comments/oi2nmk/question_regarding_ultrasound/
