title: Simulation of abnormal pulmonary thallium-201 activity following mastectomy.
abstract: Increased uptake of activity in one lung field was found on postexercise Tl-201 images in a woman who had undergone a previous mastectomy on that side. This was probably related to a partial loss of normal tissue attenuation following surgery, resulting in a simulation of abnormal pulmonary activity.
