Canadian Agency for Drugs and Technologies in Health
Record ID 32011000949
Authors' recommendations: Data from one retrospective study that compared V/Q scan using Technegas to CTPA in pregnant women indicated that V/Q scan have a higher diagnostic accuracy than CTPA for pulmonary emboli. No evidence on the cost-effectiveness of V/Q scan versus CTPA for diagnosing pulmonary embolism in hospitalized patients was identified.
