[An evaluation of the risks of pulmonary scintigraphy (author's transl)]

Scintipulmography is a method for testing cardiopulmonary function in diagnosis and control. Standardized X-ray examinations are preferable from a radio-hygienic view. In perfusion scintigraphy microspheres are better for examining terminal vessels and are of lower risk. Short-lived radionuclides, e.g., 99mTc or 113mIn, should be used as markers. Recent physiologic findings indicate injection by bolus during the middle phase of inspiration while the patient holds his breath. General and individual risks and the diagnostic advantages of this method are discussed. Normally, the advantages outweigh the risks, as demonstrated in a case of artificial pulmonary embolism. For high-risk patients, however, inhalation scintigraphy should be made available as a standard radiologic method.
