  		Fig. 3. —CT angiogram of 52-year-old man with chronic thromboembolic pulmonary hypertension shows three dilated bronchial arteries (arrows). Each individual vessel was followed down to hili for adequate position to measure cross-sectional area using double-threshold of 100-3072 H.

  		Fig. 4. —Scatterplot of shunt volume and cross-sectional area of bronchial arteries shows high correlation between shunt volume, as determined by phase-contrast MR imaging, and cross-sectional area of bronchial arteries, as determined by helical CT. Measuring cross-sectional area of dilated bronchial arteries allows estimation of postoperative increase in pulmonary blood flow.
