Quantitative CT Evaluation of Small Pulmonary Vessels in Patients with Acute Pulmonary Embolism

Conclusions Although the absolute %CSA < 5 and CT obstruction index were not significantly correlated, the changes in the values of the two parameters had a significant correlation. Changes in %CSA < 5, which can be obtained easily, can be used as biomarker of therapeutic response in patients with acute PE.
