Emergency nuclear medicine

Despite the widespread clinical acceptance of new imaging modalities in the evaluation of acutely ill patients, there are still a number of applications for radionuclide scintigraphy. The unique ability of tracers to evaluate organ function or localized tissue dysfunction often can provide more useful information than strictly anatomic imaging modalities. Although the ventilation-perfusion study probably remains the dominant emergency procedure in most nuclear medicine laboratories, other procedures, such as those described herein, play an important role and should be available for acutely injured or ill patients.
