目的 探讨多层螺旋CT(MSCT)多平面重建(MPR)、容积再现(VR)技术对外伤性肋骨骨折的诊断价值。方法 回顾性分析 2022 年 1-10 月四川大学华西医院龙泉医院收治的 90 例外伤性肋骨骨折患者的MSCT图像，根据轴位薄层图像分别结合MPR、VR重建图像进行诊断，比较两种重建技术对肋骨骨折的诊断价值。结果 90 例患者共 371 处肋骨骨折，其中错位骨折 254 处，MPR及VR的诊断敏感度率分别为 98。03%(249/254)、96。85%(246/254)，误诊率分别为 0。40%(1/250)、0。40%(1/247)，MPR及VR对肋骨错位骨折诊断的敏感度及误诊率比较，差异无统计学意义(P>0。05)。MPR及VR对 117 处无错位骨折的诊断敏感度分别为 88。03%(103/117)、74。36%(87/117)，误诊率分别为 2。83%(3/106)、5。43%(5/92);MPR及VR对总的肋骨骨折诊断敏感度分别为 94。88%(352/371)、89。76(333/371)，误诊率分别为 1。12%(4/356)、1。77%(6/339);MPR对无错位骨折及总的肋骨骨折诊断敏感度高于VR，差异有统计学意义(P<0。05)，而误诊率差异无统计学意义(P>0。05)。VR平均诊断时间(174。59±21。64)s短于MPR平均诊断时间(211。66±27。70)s，差异具有统计学意义(P<0。05)。结论 VR诊断用时短，MPR对无错位骨折敏感度更高，合理利用两种重建技术能提高肋骨骨折诊断效率和准确性。
The diagnostic value of MPR and VR reconstruction techniques of multi-slice spiral CT in traumatic rib fractures
Objective To explore the diagnostic value of multiplane reconstruction(MPR)and volume rendering(VR)techniques of multi-slice spiral CT(MSCT)for traumatic rib fractures.Methods A retrospective analysis was conducted on the MSCT images of 90 patients with traumatic rib fractures who were treated at West China Longquan Hospital of Sichuan University from January to October 2022.The axial images with thin lamina were combined with MPR and VR reconstruction images for diagnosis,and the diagnostic value of the two reconstruction techniques for rib fractures was compared.Results A total of 371 rib fractures were found in 90 patients,including 254 dislocation fractures.The diagnostic sensitivity rates of MPR and VR were 98.03%(249/254)and 96.85%(246/254),respectively,with misdiagnosis rates of 0.40%(1/250)and 0.40%(1/247).The sensitivity and misdiagnosis rates of MPR and VR in the diagnosis of rib dislocation fractures were compared,without statistically significant differences(P>0.05).The diagnostic sensitivity of MPR and VR for 117 non-dislocation fractures was 88.03%(103/117)and 74.36%(87/117),respectively,with misdiagnosis rates of 2.83%(3/106)and 5.43%(5/92).The diagnostic sensitivity of MPR and VR for total rib fractures was 94.88%(352/371)and 89.76(333/371),respectively,with misdiagnosis rates of 1.12%(4/356)and 1.77%(6/339).The sensitivity of MPR in the diagnosis of non-dislocation fractures and total fractures was higher than that of VR,with statistically significant difference(P<0.05),but without statistically significant difference in terms of misdiagnosis rate(P>0.05).The average diagnostic time of VR(174.59±21.64)s was shorter than that of MPR(211.66±27.70)s,with statistically significant difference(P<0.05).Conclusion VR images have shorter diagnostic time,and MPR is more sensitive to non-dislocation fractures.Reasonable use of the two reconstruction techniques can improve the diagnostic efficiency and accuracy of rib fractures.
