Comparative Study Clinical TrialPulmonary embolism revealed on helical CT angiography: comparison with ventilation-perfusion radionuclide lung scanning.
We compared helical CT angiography and ventilation-perfusion radionuclide lung scanning as initial tests in the diagnosis of acute pulmonary embolism. ⋯ Helical CT angiography could replace ventilation-perfusion radionuclide lung scanning as the initial test for screening patients who are clinically suspected of having pulmonary embolism.
