A vascular imaging method and device are provided according to the embodiments of the present disclosure. The method includes: scanning a region where a vessel is located to obtain a noncontrast enhanced scan image and a contrast enhanced image, and performing subtraction on the contrast enhanced image by using a bone region in the noncontrast enhanced scan image to obtain a subtraction image then detecting a vascular region of the vessel in the contrast enhanced image finally, combining the subtraction image with the vascular region of the vessel to obtain an angiography image of the vessel. According to the present disclosure, the vascular region in which the vessel passes through the bone is maintained in the subtraction image.
