Objective To assess the correlation between spectral CT parameters and perfusion parameters in rabbit VX2 liver tumor model. Methods 24 rabbits with VX2 liver tumor underwent GSI perfusion one- stop CT scan to generate spectral images and perfusion images. The enhanced borders of tumors were stained immunohistochemically with CD34,MVD was shown by anti- CD34. The correlation of iodine concentration of tumor with perfusion parameters and MVD were analyzed by using Pearson's correlation analysis. Results The ...
lates strongly with perfusion parameters and MVD,which can reflect tumor blood supply changes.CT灌注成像(computed tomography perfusion,CTP)虽然可以定量评估肝内实质性病灶的血流动力学信息[1-2],但是其高辐射剂量限制了其在临床的推广使用[1,3]。近年来发展的CT能?
