Abstract:
Objective：To investigate the imaging features of multi slice spiral CT (MDCT） in the lung adenocarcinoma of the ground glass density nodule.Methods：To analyze the pathology of ground glass density nodules (GGNs） in adenocarcinoma of lung cancer in 31 cases with complete MDCT data，the MPR and multi window processing，of GGNs morphology (round or oval，irregular shape)，lung tumor interface (clearly rough，fuzzy unbounded)，edge shape (short dense burr，shallow lobulation，cusp sign)，internal structure (solid components and bronchial air sign)，and adjacent structures change (pleural indentation sign，blood vessel bundle syndrome） and enhance the performance of the in-depth were analyzed.Results：In 29 cases of tumor body round and ovoid，lung tumor interface clearly was found in 27 cases，leaf syndrome in 19 cases，spiculation in 14 cases，pleural indentation sign in 13 cases，vacuole sign in 11 cases，vascular convergence sign in 8 cases，7 cases of air bronchogram，GGNs solid components enhanced amplitude 40~60Hu in 15 cases.Conclusion：Careful identification of the MDCT features of lung adenocarcinoma with glass density nodule is of good value in improving the diagnosis and differential diagnosis of GGNs lung adenocarcinoma.
