Overview
Chest CT scan and CT angiography may be helpful in the evaluation of a patient with hemoptysis. It is useful for 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, and assisting the interventional radiologist prior to treatment. CT scan is not helpful in unstable patients, patients with active bleeding who require bronchoscopy intervention, and patients with bilateral lung abnormalities.
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]
