ANALYSIS OF CT FEATURES OF NON SMALL CELL LUNG CANCER OF DIFFERENT PATHOLOGICAL TYPES

Objective: To analyze the CT features of non small cell lung cancer of different pathological types. Methods: The CT features of 117 cases non small cell lung cancer patients(squamous carcinoma 60 cases, adenocarcinoma 57 cases) were retrospectively analyzed.Results: In adenocarcinoma, the occurrence rate of ground glass opacity, speculation, pleural indentation, vascular convergence sign, air-bronchogram were obviously higher than squamous carcinoma(P0.05). In squamous carcinoma, the occurrence rate of voids, necrosis, bronchial truncated sign, obstructive pneumonia or atelectasis were obviously higher than adenocarcinoma(P 0.05). There had no statistically signifi cant differences between squamous carcinoma and adenocarcinoma about age, plain CT value, growth of enhanced scanning, lobulation, vacuole sign, spinous sign and calcif ication(P 0.05).Conclusions: The CT features of non small cell lung cancer of different pathological types are different, which can be used as one of the objective evidence of clinical preliminary diagnosis, but still need carefully differential diagnosis.
