Fig. 2B Localized increase in vascular resistance in 69-year-old woman with
breast cancer who has right-sided talc pleurodesis. CT pulmonary angiogram 3
days after A using 110 mL of Isovue 370 at 4 mL/s and 22-second
scanning delay. Note good opacification of right lower lobe pulmonary arteries
(arrows). This image illustrates that peripheral vascular resistance
can be overcome with large volume of contrast material injected rapidly and by
acquiring images at very end of injection.
