CESM is a technique to detect abnormal contrast enhancement by dynamic iodinated contrast medium study via intravenous injection using digital mammographic unit on the basis of subtraction of low and high energies. The dynamic images are displayed to evaluate the depletion. The breast cancer will depict the contrast. The result is more sensitive and specific than CE-MRI. The other advantages to CE-MRI are lower cost of equipment, examination, contrast medium, shorter time of study and claustrophobia to MRI. It is recommended for the detection, extension of breast cancer or problem cases.
