Physics and Practical Considerations of CEDM
This chapter covers the physics theory underlying iodine contrast enhanced digital mammography. We cover two methods of imaging iodine, baseline subtraction and dual energy subtraction. The chapter discusses the x-ray absorption properties of iodine, and imaging x-ray filters and x-ray tube kilovoltages needed for the dual energy subtraction method, as well as typical radiation doses for the procedure. The imaging workflow and time sequence of the procedure are shown. The known clinical performance of iodine breast imaging is briefly reviewed, and the procedure is compared to the common gadolinium breast MRI method. The differences between 2D and 3D iodinated contrast mammography are discussed. Finally, example images are shown that illustrate the subtraction process, and imaging in dense breasts.
