| 目的 探讨多层螺旋CT后处理技术对局灶性肺炎的诊断价值。方法 多层螺旋CT扫描经病理证实的局灶性肺炎35例,分析薄层重建、多平面重建(MPR)及容积显示技术(VRT)对局灶性肺炎征象的显示及价值,并与常规横断面对比分析。结果 35例病灶均位于肺野周边部,病变以宽基底与胸膜相连26例,病变边缘呈锯齿状或有粗长毛刺28例,具有周围血管充血聚拢25例,多层螺旋CT薄层重建、MPR及VRT在显示局灶性肺炎的形态、支气管血管集束征及与胸膜的关系方面优于常规横断面。 |

| Objective To evaluate the value of multi-slice spiral CT (MSCT) post-processing technique in diagnosing focal pneumonias. Methods Thirty-fivepatientswith focalpneumonia proved pathologically were studied with MSCT. After scanning,retrospective thin-slice reconstruction, multi-planar reconstruction (MPR) and volume rendering technique (VRT) images were obtained. These images were analyzed and compared with conventional axial images. Results All 35 lesions were located in peripheral lung field. Extensive pleural thickening was found in 26, 28of 35 lesions had an irregular margin or large coarse spicule, convergence of vessels in 25.Thin-slice axial reconstruction, MPR and VRT was superior to conventional axial reconstruction in judging the shape, bronchovascular convergence and relation to the pleura of focalpneumonia. Conclusion By combination with thin-slice reconstruction, MPR and VRT, MSCT can demonstrate more intuitionisticly and tridimensionally pathognomonic signs of focalpneumonias, providing more information for the diagnosis of focalpneumonias. |
