Image fusion-augmented angiography to guide cannulation during adrenal vein sampling (AVS) entails fusion between preprocedural CT images on which ring markers indicate adrenal vein ostia and live digital subtraction angiography fluoroscopic images. In patients who underwent adrenal vein sampling (18 without, 23 with image fusion-augmented angiography), image fusion-augmented angiography increased the success rate of right adrenal vein cannulation (55.6% to 87.0%; = .04) and reduced fluoroscopy time (23.7 to 16.3 minutes; = .03) and dose area product (532,195 to 91,403 mGy ∙ cm; = .006).
图像融合增强血管造影指导肾上腺静脉采样 (AVS) 时，需要将带有环标记的表示肾上腺静脉口的术前 CT 图像与实时数字减影血管造影荧光透视图像融合。在接受肾上腺静脉采样的患者中（18 例未进行图像融合增强血管造影，23 例进行图像融合增强血管造影），图像融合增强血管造影增加了右侧肾上腺静脉插管的成功率（55.6%至 87.0%； =.04），并减少了透视时间（23.7 至 16.3 分钟； =.03）和剂量面积乘积（532195 至 91403 mGy ∙ cm； =.006）。
