目的探讨多层螺旋CT多平面重建(MPR)对周围性肺癌的早期诊断价值。方法对18例经临床病理确诊的、直径≤3cm的周围性肺癌病例进行多层螺旋CT扫描并MPR,分析其影像特征。结果18例中具有深分叶征15例,短毛刺征13例,空泡征5例,支气管截断5例,局部狭窄或增厚4例,胸膜局限性增厚、胸膜凹陷征8例,血管受侵犯4例,血管束征6例,细支气管气相8例。结论16层螺旋CT的MPR技术对周围性肺癌的早期诊断具有重要价值。
Objective To investigate the value of multislice spiral multiplanar reconstruction (MPR) in the early diagnosis of peripheral lung cancer. Methods 18 cases of clinically and pathologically diagnosed peripheral lung cancer with a diameter of less than 3 cm were examined with multi-slice spiral CT and MPR to analyze their imaging features. Results Among the 18 cases, there were 15 cases with deep lobulation, 13 cases with short spiculation, 5 cases with vacuolization, 5 cases with bronchial truncation, 4 cases with local stenosis or thickening, thickened pleural, 8 cases with pleural indentation, 4 cases of violations, 6 cases of vascular bundle signs, bronchial gas phase in 8 cases. Conclusion The 16-slice spiral CT MPR technique is of great value in the early diagnosis of peripheral lung cancer.
