title: Synergistic cytotoxicity of iodinated contrast agents and x-radiation.
abstract: The synergistic cytotoxicity of iodinated radiologic contrast agents and x-radiation is discussed. Experiments are described illustrating the phenomenon and lending support to the view that it is mediated by energetic photoelectrons. Some of its practical implications are indicated.
