目的旨在探讨多层螺旋CT容积 再现成像在诊断四肢骨折中的应用价值。 方法 选取我院2017年4月-2017年12月收 治的59例四肢骨折患者，均行CT检查，收 集患者影像学资料集临床资料，比较CT 平扫、CT容积再现成像对不同部位骨折的 成像质量水平，分析多层螺旋CT容积再现 成像在诊断四肢骨折中的应用价值。结果 共59例患者，肘关节骨折19例，腕关节 骨折12例，膝关节骨折9例，踝关节骨折 8例，股骨骨折者11例。在不同骨折部位 图像质量评分比较中，VR对肘、腕、膝、 踝关节骨折、股骨骨折的图像质量评分均 明显高于CT平扫，差异具体统计学意义(t 分别为3.807、4.143、4.346、2.971、 4.660，P<0.05)。VR图像质量优良率为 100%，CT平扫图像质量优良率为98.30%， 两者数据差异无统计学意义(χ2 =1.009， P=0.315)。结论 多层螺旋CT容积再现成 像可清晰显示四肢骨折的具体情况，图像 成像质量高，更有利于影像准确诊断，值 得临床推广。

Objective To explore the application value of volume rendering of multislice spiral CT in the diagnosis of limb fractures. Methods A total of 59 patients with limb fractures admitted and treated in our hospital from April 2017 to December 2017 were selected. To compare the imaging quality of CT non-enhanced scan and CT volume rendering for different parts of fractures, and to analyze the application value of volume rendering of multi-slice spiral CT in diagnosing limb fractures. Results The clinical data of 59 patients showed that there were 19 cases of elbow fracture, 12 cases of wrist fracture, 9 cases of knee fracture, 8 cases of ankle fracture and 11 cases of femoral fracture. In comparison of image quality scores of different fracture sites, VR showed significantly higher image quality scores of elbow fracture, wrist fracture, knee fracture, ankle fracture and femur fracture than that of CT non-enhanced scan, and the differences were statistically significant (t value was 3.807, 4.143, 4.346, 2.971, 4.660, P<0.05). The excellent and good rate of VR image quality was 100%, and the excellent and good rate of CT non-enhanced scan image quality was 98.30%. The difference between the two data had no statistical significance (χ2 =1.009 P=0.315). Conclusion The volume rendering of multi-slice spiral CT can clearly and comprehensively show the specific conditions of limb fractures, and the imaging quality is high, which is more conducive to the accurate diagnosis of image and worthy of clinical promotion.
