Figure 4From: Peripheral pulmonary nodules: Relationship between multi-slice spiral CT perfusion imaging and tumor angiogenesis and VEGF expression (A-H) Inflammatory nodule found in segmentum basale anterius of inferior lobe of the right lung of a 46-year-old male. (A) Time density curve. (B-F) (original image, BF, BV, MTT, PS) TypeIII parametric maps, PS value was lower (5.63). (G) CD34 staining shows many expanded mature microvessels (× 200). (H) VEGF expression is negative (× 400).Back to article page
