Abstract
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%; <i>p</i> = .04) and reduced fluoroscopy time (23.7 to 16.3 minutes; <i>p</i> = .03) and dose area product (532,195 to 91,403 mGy ∙ cm<sup>2</sup>; <i>p</i> = .006).
