中央型肺癌MSCT三维重建、支气管镜及其病理对比研究

Contrast study of multi-slice spiral CT 3D reconstruction, bronchoscopy and pathology in central lung carcinoma

目的研究中央型肺癌(CLC)多层螺旋CT(MSCT)三维重建、支气管镜及其病理组织学表现,并对诊断结果进行对比。方法82例CLC患者,经MSCT平扫、增强动静脉期扫描、二维多平面及曲面重建(MPR及CPR)、三维容积重建(VR)、最大密度投影(MIP)及仿真内镜重建(CTVE)检查后,经支气管镜及其病理检查证实,52例又经术后病理证实。并将MSCT诊断结果与支气管镜及手术病理结果进行统计学对比分析。结果82例CLC的手术分型:腔内结节型7例,环状狭窄型27例,偏心狭窄截断型48例。MPR及CPR、MIP、CTVE诊断结果与横断扫描相比,差异无显著性;VR差异则有显著性。MSCT三维重建诊断结果与支气管镜及其病理相比,差异无显著性。结论MSCT三维重建能准确分型诊断CLC,评价气管、支气管树肿瘤侵犯程度与范围,同支气管镜具有相同的诊断效果。

[Objective] To study and assess the diagnosis result of multi-slice spiral CT 3D reconstruction, bronchoscopy and pathology in central lung carcinoma. [Methods] 82 cases with CLC were scanned using 16 spiral CT. Using non-enhanced axial scanning and enhanced scanning consisting of A phase, V phase, 2D MPR (multiplanar reformation) and CPR (curial reformation), 3D VR (volume rendering), MIP (maximum intensity projection), VE (virtual endoscopy), reconstruction images were acquired. Then the results of scanni...
