Fig. 1. —Time-density curve of common femoral artery and vein at level of greater trochanter after completion of CT pulmonary angiography in one patient. Note baseline or unenhanced value. Density measurement at time T₀ was obtained immediately after CT pulmonary angiography. Subsequent density measurements were obtained at 30-sec intervals for 5 min. Note difference in shape of two curves. Arterial peak occurs earlier than venous peak and arterial enhancement subsequently decreases more rapidly. Eventually the two curves decrease to same level.
