Figure 1

Pulmonary transit time (PTT). Time-resolved atrial short-axis SSFP CMR images (TR/TE 2.5/1.2 ms; flip angle 50°) bisecting the pulmonary trunk (PT) and the left atrium (LA) acquired during the first pass of an intravenous bolus of CMR contrast agent (Gd-DOTA). Panels A-C show the passage for 2 mL contrast bolus through the PT to the LA. Contrast intensity was measured in a region of interest in the PT and the LA, respectively. Time (t) is shown in seconds (s) in the lower corner on right hand side of the respective panel. A: time of contrast bolus injection, B: contrast bolus passing through PT, and C: arrival in LA. Note the change in signal intensity over time in the respective regions of interest.
