Isn’t it best to keep trigger in Superior vena cava?

You can read me a ct?

Well we use superior vein cava which gives us results far more substantial

you use the SVC as the ROI for your pulmonary emboli studies? Can you explain how you do it? How much delay do you put?

@@ThoracicRadiology You don't even need to ROI the SVC. Turn the auto trigger/dynamic phase off and manually watch it yourself. Keep your initial slice at the location you are using now. Use a 3-5 second delay before monitoring. The very first large vessel in that monitoring slice (just off the RT pulmonary artery) that lights up real bright is the SVC. It is in your video you posted. Once you see that, you can manually start the scan yourself. I used this technique on a GE Lightspeed 16 slice I used to work on, and always hit all the contrast in the pulmonary phase with little or no Arterial flow. Beautiful studies. However, when using faster scanners like 64 or above, be careful because you can go too early on a patient with a very low cardiac output (e.g., elderly patient). On the 64 and 128 slices using ROI at the pulomary trunk I haven't had any late boluses. I have also used the RT atrium and RT ventricle as ROI's with similar results. Your technologists just have to remember blood flow from A&P: SVC-> R Atrium-->R Ventricle-->Pulmonary arteries. Hope that helps
