64层螺旋CT三维重建和多平面重建诊断鼻骨骨折应用价值探讨

目的：探讨64层螺旋CT三维重建（3D）和多平面重建（MPR）技术在鼻骨骨折中的应用。方法：对医院近期102例鼻区骨折患者采用64排螺旋CT轴位薄层螺旋扫描,在工作站上使用三维重建（3D）和多平面重建（MPR）技术观察鼻区骨折影像表现。结果：鼻骨骨折102例,错位性骨折47例,非错位性骨折55例,双侧鼻骨骨折46例,单侧22例（左侧13例右侧9例）,鼻中隔骨折15例,鼻骨骨折伴发上颌骨额突骨折13例,单纯缝合分离6例（鼻上颌缝分离3例、鼻额缝分离2例、两侧鼻骨间缝分离1例）。所有鼻骨骨折经3D及MPR成像后均能立体显示骨折的部位、形态、类型、塌陷程度及三维空间信息。结论：64层螺旋CT3D及MPR技术可以提高鼻骨骨折诊断的准确性,并为临床医师选择治疗方案提供更有价值的信息。

Clinical Application of 64-Slice CT with 3D and MPR for Detecting Nasal Bone Fracture

Objective To discuss 64-slice CT three-dimensional reconstruction （3D） and MPR （MPR） in the application of the nasal bone fracture. Mothods 102 patients with recent nasal fracture in our hospital underwent 64-slice CT scan axial thin spiral. Nasal fracture imaging was observed using workstations in the three-dimensional reconstruction （3D） and MPR （MPR）. Results 102 cases of nasal bone fracture, dislocation fractures in 47 cases, non-fracture dislocation of the 55 cases, 46 cases of bilateral nasal bone fracture, unilateral 22 cases（13 cases the left side of the right of nine cases）, 15 cases of fracture of the nasal septum, nasal bone fracture associated with maxillary The amount of bone fracture in 13 cases, only six cases of separation suture. All the nasal bone fractures 3D imaging and after the MPR can display three-dimensional fractures of the location, shape, type, degree of collapse and three-dimensional information. Conclusion 64-slice CT3D and MPR technology can improve the accuracy of diagnosis of the nasal bone fracture, and provide valuable information for clinicians in the choice of treatment program.Chinese Medical Equipment Journal,2009,30（9） ：77-78]
