The article presents information about a study that compares helical computed tomography (CT) and ventilation-perfusion (V/Q) scan in their ability to detect acute pulmonary embolism. The data for the study was derived from MEDLINE and EMBASE/Excerpta Medica. Selected articles on helical CT were limited to those published between 1990 and 2003, and articles on V/Q scan were limited to those published between 1985 and 2003. The study concluded that CT has greater discriminatory power than V/Q scan for excluding pulmonary embolism.
