多层螺旋CT在周围型肺癌和局灶性机化性肺炎鉴别诊断中的价值
Value of multi-slice spiral CT in the differential diagnosis of peripheral lung cancer and focal organizing pneumonia
摘要
Abstract
Objective: To explore the diagnosis value of multi-slice spiral CT (MSCT) on peripheral lung cancer (PLC) and focal organizing pneumonia (FOP).Methods: CT examination and clinical data of 78 patients with PLC (PLC group) and 35 patients with FOP (FOP group) were collected, and the features of CT scan and enhanced imaging were analysed contrastively.Results: The outer zone distribution rate of the PLC group was lower than that of the FOP group (44.87% vs. 80.00%), while the inner zone distribution rate was higher than that of the FOP group (24.36% vs. 0), the differences were both statistically significant (P<0.05); there were statistically significant differences in large lesions cavity (25.71% vs. 73.68%), close to the pleura (22.86% vs. 84.21%) between the two groups (P<0.05); and there were statistically signiflcant diflerences in vessel tract syndrome (large lesions 80.00% vs. 36.84%, small lesions 72.09% vs. 31.25%), burr, bronchial inflatable syndrome (large lesions 31.43% vs. 78.95%, small lesions 30.23% vs. 75.00%), structure loosing (large lesions 5.71% vs. 47.37%, small lesions 4.65% vs. 43.75%), pleural indentation (large lesions 0 vs. 52.63%, small lesions 20.93% vs. 81.25%) of the two groups (P<0.05), there were not statistical signiflcant diflerences in the rest signs between groups (P>0.05); the patients of the two groups underwent enhanced scan in arterial and venous phase, the arterial phase net added CT value [large lesions (18.61±9.55) Hu vs. (29.60±12.35) Hu; small lesions (19.34±9.06) Hu vs. (28.72±11.09) Hu] and the total added CT value [large lesions (32.76±10.91) Hu vs. (44.53±12.29) Hu; small lesions (29.45±10.70) Hu vs. (41.10±11.89) Hu] of the PLC group were lower than those of the FOP group (P<0.01), the diflerences were statistically significant.Conclusion: CT signs and strengthening characteristics of the PLC and the FOP have certain characteristic features and diflerences, the characteristic and diflerences can be clearly shown in MSCT, so it plays an important role in the diflerential diagnosis of the two types of lesions.关键词
