title: Acute and chronic pulmonary emboli: angiography-CT correlation.
abstract: 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.
  
  
  CONCLUSIONS
  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.
