Overview

CT scan

  • Chest CT scan may be helpful in the evaluation of a patient with hemoptysis. It is useful for:[1][2][3][4]
    • Assessing the cause of hemoptysis
    • Localizing the origin of the blood
    • Providing prognostic information by correlating between the extent of lobar involvement on high-resolution CT and the amount of bleeding
    • Assisting the interventional radiologist prior to treatment
  • CT scan is not helpful in the following patients:[5]
    • Unstable patients
    • Patients with active bleeding who require bronchoscopy intervention
    • Patients with bilateral lung abnormalities
  • CT angiography may be helpful in the diagnosis of hemoptysis.[6]
