2. Fig. 1
Representative example of instantaneous hepatic arterial flow velocity profile as assessed by intravascular Doppler flowmetry of a patient at (A) baseline and (B) during infusion of 40 μg · min−1 · kg body wt−1 adenosine into the hepatic artery. Note the different scales for flow velocities (cm/s) as displayed on the right margins.

(A) Right hepatic arteriogram with (B) magnification and diameter assessment. The vessel is perfused with adenosine via the IA catheter (visible on A). Intravascular Doppler flowmetry is performed as described. The Doppler wire (not visible on the films) is advanced under fluoroscopic control to focus Doppler insonation to the point at which diameter assessment (B) is performed. A catheter is also present in the hepatic vein.
