Radionuclide section scanning of the lungs in pulmonary embolism

A new approach to the radionuclide imaging of the lungs is illustrated in this paper, describing four patients who were subjected to section scanning of the chest in addition to conventional planar imaging. The significance of this new method in the investigation of patients suspected of having pulmonary embolism is discussed. The main advantages of the new approach include increased information with depth, clearer definition of the mediastinal space, and the detection in some instances of new lesions not seen by conventional means.
