Figure 4. — 50-year-old male with adenocarcinoma. (a) Thin-section CT shows lung cancer (arrow) in right posterior segment. (b). Thin-section contrast-enhanced multiplanar reformatted images obtained at mediastinal (left) and lung (right) window settings clearly show that posterior segmental artery (arrows) branches directly from pulmonary arterial trunk (visualization score, 5; variation probability score, 5). (c) Pulmonary arterial phase (left; time, 4.0 s), parenchymal phase (middle; time, 8.0 s), and venous phase (right; time, 12.0 s). 4D contrast-enhanced MR angiography images clearly show that posterior segmental artery (arrows) branches directly from pulmonary arterial trunk (visualization score, 5; variation probability score, 5). (d) Anterior (left) and posterior (right) cine MRI shows that posterior segmental artery (arrow) branches directly from pulmonary arterial trunk (visualization score, 4; variation probability score, 5). (e) Fresh blood imaging clearly shows that posterior segmental artery (arrow) branches directly from pulmonary arterial trunk (visualization score, 5; variation probability score, 5). (f) Time-spatial labeling inversion pulse image clearly shows that posterior segmental artery (arrow) branches directly from pulmonary arterial trunk (visualization score, 5; variation probability score, 5).
