肺结节患者多螺旋CT胸部低剂量扫描临床分析

目的:探讨肺结节患者多螺旋CT胸部低剂量扫描临床诊断效果。方法:收治肺结节患者108例,同时给予常规剂量和低剂量多螺旋CT胸部扫描,对比两种诊断方法对患者治疗的效果。结果:通过对比得出,常规剂量检查出肺结节164枚,低剂量检查得出162枚,两种剂量检查方法得出肺结节数量差异无统计学意义(P>0.05)。对常规剂量与低剂量CT扫描肺结节形态特征展开比较,患者的空洞、分叶征、胸膜粘连等一系列数量差异无统计学意义(P>0.05)。结论:多螺旋CT胸部低剂量扫描具有辐射危害小、成本低等特点,是临床检查肺结节病症的首选办法。

Value of multidetector spiral CT in diagnosis of acute thoracolumbar spinal fracture and fracture-dislocation

Objective: To investigate the diagnostic value of multidetector spiral CT (MSCT) in acute thoracolumbar spinal fracture and fracture-dislocation. Methods: CT imaging files of 152 consecutive traumatic patients with thoracolumbar fractures were retrospectively reviewed. MSCT scannings were performed with a collimation of 3-5 mm and a pitch of (5.5). The postprocessing included sagittal and coronal multiplannar reconstruction, and 3-D reconstruction.Results: There were 88 cases of compression fracture, 54 cases of burst fracture and 10 cases of fracture-dislocation. Transverse images of MSCT could visualize all fractures directly and determine whether spinal canal was intact. Postprocessing image was helpful in depicting the displacement of fragment and orientation of dislocation.Conclusions: MSCT plays an important role in diagnosis and management of acute thoracolumbar spinal fracture and fracture-dislocation.
