| ［摘要］ 目的 探讨16排螺旋CT扫描并多平面重建（MPR）在孤立性肺结节(SPN)影像诊断中的价值。方法 回顾性分析经病理证实的周围型小肺癌21例和良性SPN 29例的CT影像资料，所有患者均行16排螺旋CT容积扫描并MPR。结果 MPR图像比常规横断位扫描更能显示病灶的特殊征象，如胸膜凹陷、血管集束、小钙化、毛刺征、空泡征、棘状突起等。结论 16排螺旋CT扫描并MPR发现SPN的特殊征象更多，对区分SPN的良恶性具有重要价值。 |

| ［Abstract］ Objective To evaluate the diagnostic value of using 16-slice spiral CT scan and Multi-planar reconstruction(MPR) on solitary pulmonary nodules(SPN).Methods 21 patients with small peripheral lung cancer and 29 patients with benign SPN were confirmed by pathology and analyzed retrospectively using CT imaging data. All patients underwent 16-slice spiral CT volume scanning and MPR.Results MPR images could display more special features of lesions than conventional transverse scanning, such as pleural indentation, vascular bundle, small calcification, spicule sign, vacuole sign, spinous protuberance etc.Conclusion 16-slice spiral CT scan and MPR shows more signs of SPN than conventional transverse scanning. It is valuable to use this technique to scan SPN and distinguish between benign and malignant lung tumors. |
