| 目的 探讨围型肺癌胸膜凹陷征的MSCT及PET/CT特征,及其评估胸膜侵犯的价值。方法 收集屏气胸部CT见胸膜凹陷征、经手术病理证实的周围型肺癌72例,对所有患者行18F-FDG PET/CT全身显像和MSCT,根据MSCT表现,将胸膜凹陷征分为Ⅰ、Ⅱ和Ⅲ型,测定肿瘤胸膜连接部最大标准摄取值(SUVmax)。比较不同胸膜凹陷征类型患者胸膜侵犯发生率差异,比较不同胸膜凹陷征类型SUVmax差异,比较代谢增高、有患者中无胸膜侵犯患者SUVmax差异。结果 胸膜凹陷征Ⅰ型22例、Ⅱ型20例、Ⅲ型30例,Ⅲ型胸膜侵犯发生率[93.33%(28/30)]高于Ⅰ型和Ⅱ型[63.64%(14/22)、65.00%(13/20),P均<0.05],Ⅰ型和Ⅱ型间差异无统计学意义(P>0.05);24例胸膜侵犯患者局部胸膜摄取18F-FDG增高,其中Ⅰ型7例、Ⅱ型6例、Ⅲ型11例,三者SUVmax差异无统计学意义(1.64±0.48、1.33±0.20、1.48±0.53,P>0.05);代谢增高患者中有、无胸膜侵犯病例SUVmax差异无统计学意义(1.49±0.45 vs 1.34±0.22,P>0.05)。结论 MSCT中周围型肺癌胸膜凹陷征Ⅲ型提示肿瘤胸膜侵犯,而肿瘤胸膜连接部18F-FDG代谢状态不能反映肿瘤胸膜侵犯。 |

| Objective To analyze the MSCT and 18F-FDG PET/CT features of pleural indentation in peripheral lung cancer and investigate the value of them in detection of pleural invasion.Methods Totolly 72 patients of peripheral lung cancer confirmed by surgery pathology with pleural indentation in breath-hold CT underwent 18F-FDG PET/CT and MSCT. According to the MSCT features, the pleural indentation were divided into type Ⅰ, Ⅱ and Ⅲ and the maximum standardized uptake value (SUVmax) of the junction of the pleural and tumor was measured in PET/CT. The pleural invasion rate among different pleural indentation types, the SUVmax among different pleural indentation types in pleural invasion patients, the SUVmax between pleural invasion and pleural non-invasion patients with increased 18F-FDG uptake were compared. Results There were 22 of type Ⅰ, 20 of type Ⅱ and 30 of type Ⅲ pleural indentation, the pleural invasion rate of type Ⅲ (93.33% [28/30]) was higher than that of type Ⅰ and type Ⅱ (63.64%[14/22] and 65.00%[13/20], both P<0.05) and there was no difference between type Ⅰ and type Ⅱ (P>0.05). There were 24 pleural invasion patients with increased 18F-FDG uptake, among them 7 was type Ⅰ, 6 was type Ⅱ and 11 was type Ⅲ and no significant differences of SUVmax were found among them (1.64±0.48, 1.33±0.20, 1.48±0.53, P>0.05). There were no differences of SUVmax between pleural invasion and pleural non-invasion patients with increased 18F-FDG uptake (1.49±0.45 vs 1.34±0.22, P>0.05). Conclusion Pleural indentation of type Ⅲ in MSCT suggests pleural invasion, while 18F-FDG metabolic state of connecting part between the pleura and tumor can not reflect pleura invasion in peripheral lung cancer. |
