Figure 3From: Lung flooding enables efficient lung sonography and tumour imaging in human ex vivo and porcine in vivo lung cancer modelAdenocarcinoma in the central right inferior lobe of an excised human lung. ( a ) Computed tomography scan shows a central, peribrochial tumour. ( b ) Sonography under atelectasis: the tumour appears homogenous and is poorly demarcated (isoechogenic) from lung tissue. ( c ) Sonography after flooding: homogenous tumour tissue is hypoechoic, irregularly configured with fringe-like processes, and is well-demarcated from the normal lung parenchyma. Bronchial destruction is evident (arrow).Back to article page
