ABSTRACT
Objective To investigate the clinical value of multi-slice spiral CT (MSCT)in the diagnosis of focal pulmonary ground-glass opacity nodules(fGGO)of 1 cm or less.Methods The MSCT examination data of 95 patients with subcentimeter fGGO was analyzed and compared with pathology results.The different pathological types of fGGP lesion size,internal solid component size,mixed type ground glass nodules (mGGO)proportion and pleural sag,lesion shape,grave leaves,burr,cavitation and the boundary conditions were compared. According to the relationship of the lesions and the surrounding blood vessels,3 types were classified,and the relationship of fGGO and blood vessel were analyzed.Results The minimal lesion was 0.41 cm of 95 cases and the maximum was 0.99 cm.There was statistically signifi-cant difference in the lesion size,solid component sizes,mGGO and lobulation occupied the percentage of the group before infiltrating and the adenocarcinoma group (P 0.05).The difference was statistically significant in the leaflet occupied the percentage of the benign group com-pared with the adenocarcinoma group,and the differences of the remaining features were not statistically significant compared with the adeno-carcinoma group(P >0.05).According to the relstionship between fGGO and the vessels,patients in the benign group were type Ⅰ or typeⅡ,type Ⅲ was found in 10 cases of the group before infiltrating (25.6%),and type Ⅲ in 17 cases of the adenocarcinoma group (39.5%), the proportion of type Ⅲ of the group before infiltrating and the adenocarcinoma group was higher than that of the benign group (P <0.05). Conclusion The qualitative diagnosis of pulmonary fGGO is difficult,and the relationship between the morphology of the lesions under the MSCT and the surrounding vessels have some value for the diagnosis of the lesions.
