Rotational C-arm angiographic computed tomography (CT) with a flat-panel radiography unit permits three-dimensional (3D) reconstruction of soft tissues and blood vessels. The usefulness of this C-arm technique during transcatheter arterial chemoembolization (TACE) is unknown. The authors analyzed the role of the C-arm technique in 18 patients with unresectable liver tumors during TACE. The technique altered the catheter position anticipated by attending interventional radiologists in seven of the 18 patients (39%; 95% confidence interval [CI]: 20%, 61%) and improved the diagnostic confidence in the selected catheter position in 14 of the 18 patients (78%; 95% CI: 55%, 91%). The technique provides CT-like images that are useful to interventional radiologists during TACE.
使用平板射线摄影装置的旋转C形臂血管造影计算机断层扫描（CT）可对软组织和血管进行三维（3D）重建。这种C形臂技术在经动脉化疗栓塞术（TACE）中的作用尚不清楚。作者分析了C形臂技术在18例不可切除肝肿瘤患者TACE过程中的作用。该技术改变了18例患者中7例（39%；95%置信区间[CI]：20%，61%）介入放射科医生预期的导管位置，并提高了18例患者中14例（78%；95%CI：55%，91%）对所选导管位置的诊断信心。该技术提供了类似CT的图像，对TACE期间的介入放射科医生很有用。
