An oblique coronal multiplanar reformatted image (part A) shows the artery of Adamkiewicz (arrow) and the posterior branch (arrowhead) of the left 10th intercostal artery (ICA). An oblique sagittal partial maximum-intensity-projection image (part B) shows that the 10th ICA, the origin of the artery of Adamkiewicz, is occluded proximally at the aorta (arrowhead) and patent ICAs. It also shows collateral circulation from the 11th to 10th ICA (arrow). Imaging parameters are follows: 1.5-T imager, 3D fast spoiled gradient-echo sequence with chemical shift-selective fat suppression, 20-ms repetition time, 2.2-ms echo time, 408 flip angle, 1-mm partition thickness, 168 £ 240-mm field of view, and a 384 £ 512 matrix. The section orientation is sagittal. A total of 0.2 mmol/kg of body weight of gadopentetate dimeglumine is administered from an antecubital vein. T10: 10th thoracic vertebra.
