Table 1 Sonographic examination of lung tumours before and after lung flooding

From: Lung flooding enables efficient lung sonography and tumour imaging in human ex vivo and porcine in vivo lung cancer model

  1. Fourteen resected human lung lobes were assessed for tumour detection rate, sonomorphology, and limitations due to residual gas. CT Computed tomography, LLL Left lower lobe, LNM Lymph node metastasis, ML Middle lobe, RLL Right lower lobe, RUL Right upper lobe.
