Use of isotope scanning as an aid to the diagnosis of pulmonary embolism in the accident and emergency department.

Twenty-five patients with a clinically suggestive diagnosis of pulmonary embolism were referred directly from the accident and emergency department for a ventilation and perfusion isotope scan. On the basis of a negative scan, the authors were able to discharge 19 patients. The advantages of having direct access to isotope imaging are described.
