Abstract:
Objective:To study correlation of degree spiral CT enhancement and ultrastruction and density microvessel in peripheral lung cancer.Methods:31 cases of peripheral lung cancer comfirmed by operatien and pthology were examined with spiral computed tomography of enhancement with iodiated contrast meaterial before operaton.Ultrastructure and density microvessels were observed by transmission electron microscope and immunohistochemical method by factor Ⅷ on the specimens of the resected tumors.Results:①A increase in microvessel permeability of lung cancer resulted from gap between endotheliums of microvessel,lack of basement membrane of cracking,large cancer cell space.②The degree of spiral CT enhancement was correlated with microvessel density in peripheral lung cancer(r=0.926,?
