Fig. 2From: Correlation study between flash dual source CT perfusion imaging and regional lymph node metastasis of non-small cell lung cancerAn adenocarcinoma at the middle lobe of right lung without regional lymph node metastasis. (a) Functional maps of perfusion show that blood flow value was high (105.23 ml/100 ml/min). (b) CD34 staining showed microvessels with luminal vessels (thick arrow) and without luminal vessels (thin arrow) and the former accounted for the main part (× 200). (c) SMA staining showed more microvessels covered with completed layers of smooth muscle cells (arrows) (× 200)Back to article page
