Contrast-enhanced endoscopic ultrasonography

Figure 1 Contrast enhanced endoscopic ultrasonography exam of lung adenocarcinoma. A: Non-enhanced power Doppler image of a lung adenocarcinoma visualized in the aorto-pulmonary window from the mid-esophagus, with discrete Doppler signals in the periphery of the mass and embedding of a large branch of the left pulmonary artery; B: Same tumor visualized after contrast-enhancement with SonoVue, with a better depiction of the vascular peripheral signals and the possibility of quantification of the vascular index. The relationship to the aorta and pulmonary artery is clearly depicted.
