ABSTRACT

Objective:To explore the application value of 16-slice spiral CT multi-planar reconstruction(MPR), surface occlusion display and other image post-processing techniques in the diagnosis of peripheral lung cancer.Methods:From April 2017 to April 2019, a total of 98 patients with peripheral lung cancer admitted to the Affiliated Hospital of Hangzhou Normal University and the First People's Hospital of Jiashan County were selected.The detection rates of various signs of MPR, surface occlusion display and other image post-processing techniques in the diagnosis of peripheral lung cancer were analyzed and compared.Results:MPR in the diagnosis of peripheral lung cancer, the lobulated sign was 94.9%(93/98), the vascular bundle sign was 85.7%(84/98), the fine and short burr was 93.9%(92/98). The detection rate of vascular bundle sign and fine burr sign was higher than that of thin layer scan (χ 2=5.351, 5.023, 5.777, all P<0.05). There was no statistically significant difference between MPR and thin-layer scan in vacuolar sign and pleural indentation (χ 2=1.356, 1.333, all P>0.05). The surface occlusion in the diagnosis of peripheral lung cancer, showed 90.8%(89/98) lobulated sign and 74.5%(73/98) pleural indentation.The detection rates of lobulated sign and pleural sag were higher than those of thin layer scanning (χ 2=5.450, 6.002, all P<0.05). The detection rate of vacuole sign by surface occlusion in peripheral lung cancer diagnosis was lower than that of thin layer scan ( χ 2=5.013, P<0.05). The surface occlusion had no statistically significant difference compared with thin layer scan in the detection rate of vascular bundle sign and thin and short burr sign in the diagnosis of peripheral lung cancer (χ 2=1.256, 1.302, all P>0.05). Conclusion:In the diagnosis of various signs of peripheral lung cancer, the detection rate of 16-slice spiral CT MPR technique is high and worthy of application.
