Figure 1 Anomalous coronary artery in patients with tetralogy of Fallot. A 3-dimensional volume-rendering view shows the left anterior descending artery arising from the right coronary artery and anteriorly crossing the right ventricular outflow tract. Right coronary ostium (∗), left anterior descending artery (). PT, Pulmonary trunk.

Figure 2 Benefit of 3-dimensional imaging. Three-dimensional volume rendering produces virtual anatomic images that are very helpful for the preoperative assessment of the patient's anatomy. Ao, Aorta; PA, pulmonary artery. ∗Infundibular stenosis.

Figure 3 Stair-step artifacts on sequential acquisitions. Three different acquisition sets (∗) are seen with a decrease in contrast over time and slight stair-step artifacts that do not impair image analysis.
