Abstract:
Objective To explore the diagnostic performance and the distributive characteristics of me-diastinal lymph nodes in lung tumor with PET/CT examination .Methods Thirty-three cases of preoperative whole-body 18 F-FDG PET/CT examination revealed pulmonary lesions ,a radical surgery and lymph node dis-section patients were included in this study .PET/CT doctors read the image of PET/CT and recorded the lymph node short diameter,CT value,SUVmax,and analysed the patient′s visual graphics.The application of PET/CT a-nalysis was used for diagnosis of the mediastinal lymph nodes ,and compared with the pathological findings .Re-sul ts The diagnostic accuracy of mediastinal lymph nodes with the conventional CT method alone was 84 .1%, with the conventional PET method alone was 82.8%,with the conventional PET/CT analysis was 91.7%,with the PET/CT comprehensive analysis was 95.2%;Five benign lymph nodes were mis -diagnosed.In this study, there were eight cases of lung cancer with mediastinal or hilar lymph node metastasis ,all of the lymph nodes loca-ted in the right lung ,and in which five cases were in the inner zone .Conclusion The PET/CT comprehensive a-nalysis of lymph node performs better than either the CT method alone or the PET method alone (χ2 =9.10,P<0.05);The lesions in the inner zone are more prone to occur mediastinal lymph node metastasis .
