| 目的 探讨64排螺旋CT图像后处理技术在肋骨及肋软骨骨折中的临床应用价值。方法 回顾性分析30例55处肋骨及10处肋软骨骨折病例,采用VR、SSD、MIP和MPR(包括曲面重建)技术进行肋骨及肋软骨重建,并与X线胸片(CR/DR)和常规轴位CT图像对照。结果 在64排螺旋CT重建后发现的55处肋骨及10处肋软骨骨折中,X线平片发现肋骨骨折38/55处(69.1％),肋软骨骨折0处;常规轴位CT发现肋骨骨折 45/55处(81.8％),肋软骨骨折3/10处(30％) |

| Objective To discuss the clinical applying value of the image post-processing technique of 64-row helical CT in rib and costal cartilage fracture. Methods To review and analyze 65 points fractures of 55 points ribs and 10 points costal cartilages in 30 cases,which were performed multislice spiral CT (MSCT) scanning chest and used the volume rendering (VR), the surface-shaded display (SSD), the maximum intensity projection (MIP) and the multi-planar reformation (MPR, including curved surface reconstruction) reconstruction techniques, which compared with the chest plain film and the conventional axial CT scan. Results In 65 points fractures of 55 points ribs and 10 points costal cartilages in 30 cases, we found out 38/55(69.1％) points rib fractures, 0 point costal cartilage fracture in the chest plain film by DR/CR (digital radiography/computed radiography)and 45/55 (81.8％) points rib fractures, 3/10 (30％) points costal cartilage in the conventional CT axial scans. All rib and costal cartilage fractures were confirmed by the 64-MSCT image post-processing technology. There has statistical difference between the two groups (P＜0.01). Conclusion The 64-row helical CT image post-processing technology obviously surpasses conventional X-ray plain film and CT axial scans in rib and costal cartilage fracture. The 64-row helical CT image post-processing technology was especially hopefully for diagnosing fractures of the costal cartilage and became a sort of "the best diagnosis criteria" of costal cartilage fractures. |
