“Pulmonary Vein Sign” for Pulmonary Embolism Diagnosis in Computed Tomography Angiography
2017
Purposes
Considering that pulmonary arterial obstruction decreases venous flow, we hypothesized that filling defects in pulmonary veins can be identified in areas adjacent to pulmonary embolism (PE). This sign was named the “pulmonary vein sign” (PVS), and we evaluated its prevalence and performance for PE diagnosis in computed tomography pulmonary angiography (CTPA).
