CT三维重建对可疑膝关节骨损伤的临床应用价值

The CT three dimensional reconstruction the clinical practice value which damages to the suspicious knee joint bone

目的：探讨螺旋CT表面遮盖显示（SSD）、多平面重组（MPR）和容积再现（VRT）技术针对平片诊断的可疑膝关节骨损伤的临床应用价值.方法：对24例平片X线检查诊断可疑膝关节骨损伤的病例,行螺旋CT扫描后,运用SSD、MPR和VRT技术重建膝关节三维图像.结果：所有平片诊断可疑膝关节骨损伤的病例在行螺旋CT扫描经过三维重建处理后都得到了明确的影像诊断结果.尤其是对骨折病例的骨折分型、骨折范围、移位程度的描述上大大优于平片X线检查.减少了影像科检查的误诊和漏诊率,并为临床医师制定治疗方案提供可靠依据.

Objective： Discusses the screw CT surface cover to demonstrate （SSD）, the multilevel reorganize （MPR） and the volume reappear the （VRT） technology the clinical practice value which damages in view of the even piece diagnosis suspicious knee joint bone. Methods：Case of illness which damages to 24 example even piece X inspection diagnosis suspicious knee joint bone, after the good screw CT scanning,utilizes SSD, MPR and the VRT technology reconstruction knee joint three dimensional image. Results： All e^en piece diagnosis suspicious knee joint bone damages case of ill- ness was an expert to good expert the screw CT scanning to pass through three dimensional reconstruction processing all to obtain the explicit phantom diagnosis result. In particular to in the bone fracture case of illness bone breakdown, the bone fracture scope,the shifting degree description greatly surpasses the even piece X inspection. Reduced the phantom branch inspection error diagnostic and the rate of missed diagnosis,and formulates the treatment plan for clinician to provide the reliable basis.
