Abstract：Objective To analyze CT appearances and pathological basis of the solid components of mixture ground -glass ( MGGO) nodules in adenocarcinoma in situ ( AIS) and minimally invasive adenocarcinom ( MIA) .Methods CT appearing as MGGO of AIS group (20 cases) and MIA group (20 cases) were retrospectively analyzed, and the morphology, distribution, bor-der, number and edge of the solid components in the two groups were analyzed and compared with pathological results .Results The real component of the AIS group was found to be a cord like , it seemed to be a thickening of the lung texture , the state was clear, mainly located in the center of the glass lesions , and the edge of the lesion was not divided leaves , burr, pleural indentation and other malignant signs .MIA solid component showed multiple patchy , cluster distribution and situation of mutual gather , irreg-ular in shape , the realm of vague , also the edge of the lesions prone to lobulation , spiculation , pleural sag signs of malignancy . Conclusion Comprehensive analysis of AIS and MIA in the real components of the CT performance may help to the diagnosis and differential diagnosis of MIA and AIS .The characteristic of the real components of the tissue pathology is the basis of the differ-ence between the two images .
