WebOligemia, or a decrease in the flow rate due to acute pulmonary embolism, is often identified on angiography [34, 35]. In my experience, this finding is more often seen on angiography than on CT; this discrepancy is thought to be related to the larger temporal window of IV contrast material for CT as compared with angiography.

WebOct 12, 2012 · Depending on the CT resolution needed, you can use a 22g where you needed a 20g or 18g and still get good images. We occasionally even use a 24g for those patients who only have tiny veins. This is a really excellent product because it doesn't piston nearly as much as a distal open end catheter so it doesn't infiltrate nearly as easily. WebThe flow rate during high-pressure injection was determined using a Medrad Mark V ProVis® Power Injector and Medrad 60" coiled tubing with contrast media at room temperature. The contrast media was delivered at various flow rates while the pressure was recorded at the injector and at the catheter. Two
