Imaging studies that can be used in the evaluation of antithrombin III deficiency include the following:

  • Echocardiography: This should be performed in all patients with antithrombin III deficiency, especially if they have evidence of arterial thrombus
  • Doppler ultrasonography: Doppler ultrasonography of the affected extremity with compression should be performed at diagnosis and then used in follow-up to determine resolution of an acute thrombus
  • Ventilation-perfusion scanning: Pulmonary thrombosis can be imaged with this modality
