Objective: The objective of our study was to review the classic direct and indirect angiographic signs of acute and chronic pulmonary embolism (PE) and correlate these findings with MDCT.
Conclusion: CT and angiography have complementary roles in the accurate diagnosis of acute and chronic thromboembolic disease. Conventional angiography should be used as a problem-solving technique after CT angiography has been performed because CT angiography is less invasive.
