Study Arms (1)

All eligible patients

OTHER

All patients undergo the same CT protocol in addition to standard care.

Diagnostic Test: Dual energy / spectral portal venous chest computed tomography

Interventions

Each patient undergoes an additional dual energy / spectral chest CT in addition to standard care CTPA. The intervention is performed immediately after standard care CTPA.

All eligible patients
