"Lung Scintigraphy has a superior sensitivity combined with adequate specificity and low rate of non-diagnostic tests. The low radiation dose, the possibility to quantify the degree of embolism and to use the test for follow-up treatment of embolism and its feasibility in very sick patients contribute to the priority of Lung Scintigraphy over Computed Tomographic Pulmonary Angiography".
