Abstract:
Objective To investigate the value of multi-slice spiral CT in the diagnosis of small lung adenocarcinomas. Methods Fourteen patients underwent thin multi-slice spiral CT scan. Images were post-processed and 2 kinds of postprocessing images including multiple planar reconstruction (MPR) and minimum intensity projection (MinIP) were performed. The image characteristics of the tumors assessed by multi-slice spiral CT were correlated with the clinical/pathological manifestation. Results In 14 cases of small lung adenocarcinoma, tumor density had two forms. Four of five cases with localized bronchioloalveolar carcinoma (LBAC) showed total or partial ground-glass opacity, and 9 adenocarcinomas showed solid attenuation. 3 cases with LBAC showed partial ground-glass opacity mixed with airway dilatation. MPR in 14 patients clearly showed interlobar pleura and image characteristics of the tumors. MinIP in 10 cases were able to demonstrate 5～6 scale bronchial divisions and presented air bronchogram of tumors in a vivid way. Conclusion Thin multi-slice spiral CT scan and reconstruction images can play an important role and are the valuable method in the diagnosis of small lung adenocarcinomas.
