Figure 7From: Effect of lung flooding and high-intensity focused ultrasound on lung tumours: an experimental study in an ex vivo human cancer model and simulated in vivo tumours in pigsNicotinamide adenine dinucleotide phosphate (NADPH)-diaphorase staining. There is a sharp demarcation between vital lung tissue (A) and ablated tumour tissue (B). Immediately after ex vivo high-intensity focused ultrasound application, NADPH-diaphorase staining showed a lack of uptake of the vitality stain in finger-shaped tumour extensions (B).Back to article page
