Key result
Computed tomography findings of pulmonary artery expansion were present in 86% of patients with pulmonary artery sarcoma compared to 3% of patients with pulmonary embolism (P<0.0001).
Why the study?
Can computed tomography (CT) findings differentiate pulmonary artery sarcoma from pulmonary embolism?
Observational (n=47)
Blinded to diagnosis
Can computed tomography (CT) findings differentiate pulmonary artery sarcoma from pulmonary embolism?
Absolute Event Rate: 86% vs 3%
p-value: p=<0.0001
CT imaging features such as complete luminal occupation, artery expansion, and extraluminal extension can reliably differentiate rare pulmonary artery sarcomas from common pulmonary embolisms.

May aid CT differentiation of pulmonary artery sarcoma from embolism; leaves open prospective validation before clinical adoption.
Yi et al. (2004) conducted an observational in Pulmonary artery sarcoma and pulmonary embolism (n=47). Pulmonary artery sarcoma vs. Pulmonary embolism was evaluated on Expansion of the pulmonary arteries on CT (p=<0.0001). Computed tomography findings of pulmonary artery expansion were present in 86% of patients with pulmonary artery sarcoma compared to 3% of patients with pulmonary embolism (P<0.0001).
