Multi-slice spiral CT Diagnosis of peripheral small Lung Cancer(Analysis of 40 Cases)

Purpose: To explore multi-slice spiral CT (MSCT) manifestion of peripheral small lung cancer (PSLC) and evaluate CT diagnostic accuracy of MSCT in lung cancer. Materials and methods: MSCT signs of 40 cases of pathologically proved lung cancer were in were studied retrospectively. Results: PSLC of 40 cases had one of the following patterns: adenocarcinoma(32), squamous carcinoma(5), small cell carcinoma(3). Among 40 cases with PSLC,main sign on CT were found to be deep lobulation sign in 30,marginal speculated sign in 25,vacuole sign in 5, pleural indentation sign in 8, and vascularnotch sign in 7. Conclusion: MSCT signs of PSLC play an important role in the diagnose,it can improve the accuracy to diagnose PSLC.
