I also wonder where is the role of D-dimer. We use it a lot to exclude PE. Sometimes we do D dimer first, if it's normal, no further PE workup. In our clinic setting, V/Q scan not often done, b/c it requires NL lung, most of pt at PE age has COPD, asthma or pulmonary hypertension d/t sleep apnea. So most of the time we do chest CT to see PE.
Thanks for the detailed clarification. I looked up in master the boards and you're right it clearly states that Spiral CT is the test of choice if CXR is abnormal.
It wont let me post the link it keeps saying "error" but if you look at this link and take out the spaces you will see another source outside of uptodate. e m e d i c i n e . m e d s c a p e . c o m / a r t i c l e / 3 6 1 1 3 1 - o v e r v i e w
I think your sources are antiquated. CT is only 86% sensitive for proximal emboli and 63% sensitive for subsegmental vessels and is therefore not the 1st line, however the only disadvantage of VQ scan is that it tends to miss peripheral emboli, however it is still preferred. My source is uptodate.
thank you soooooooo much ...its realy a great video
