An angiographic examination method for performing a subtraction angiography for the detection of microembolizations includes capturing at least one pre-operative pre-contrast image and at least one pre-operative post-contrast image having a vascular tree filled with contrast medium. The method also includes subtracting the pre-contrast image and the post-contrast image in order to produce a pre-operative subtraction image. The method includes capturing at least one post-operative post-contrast image having a vascular tree filled with contrast medium, and subtracting a pre-contrast image and the post-operative post-contrast image in order to produce a post-operative subtraction image. The method also includes subtracting the pre-operative subtraction image and the post-operative subtraction image in order to produce a third subtraction image, and reproducing the third subtraction image.
