【摘要】 目的:比较X线、CT和MRI在骨折中的诊断价值。方法:回顾分析168例骨折患者的影像资料(包括X线平片、CT和MRI)。应用X2检验对X线平片、CT和MRI显示骨折敏感度进行统计分析。结果:168例患者的408处骨折中,X线平片、CT和MRI显示骨折数目分别为298、396和406处。CT和MRI显示骨折敏感度相近(x2=0.17,P>0.05),2者均优于X线平片(x2值分别为15.01和14.46,P值均<0.05)。MRI除显示骨折外,显示骨挫伤163例,韧带损伤65例,脊髓损伤37例,关节腔及关节囊积液(血-液平)46例,骨折累及软骨33例。结论:MRI能发现X线平片和CT不能显示的骨髓、软骨、韧带及脊髓等损伤。骨折合并症及骨折分期诊断价值优于X线平片和CT。更多还原

【Abstract】 Objective: To compare X- ray,CT,and MRI in detection of bone fracture. Methods: 168 cases of bone fracture with imaging diagnosis( including X- Ray,CT and MRI) were analyzed retrospectively. The Chi- square test was used to analyze the uniformity of bone fracture detected by X- ray,CT,and MRI. Results: Of the 408 bone fracture in 168 patients,298 bone fractures were found by X- ray,396 bone fracture by CT and 406 bone fracture by MRI. With regard to the detection of bone fracture,there was no difference between CT and MRI( x2= 0. 17,P > 0. 05) and there was significant difference between CT and X- ray or MRI and X- ray( x2= 15. 01 and 14. 46,P < 0. 05). MRI was better than other X- ray and CT in detect of bone fracture. The else changes of bone fracture were determined by MRI,which included bone contusion in 163 patients,ligaments injuries in 65 patients,spinal cord injuries in 37 patients,articular cavity hydrops in 46 patients and cartilage injuries in 33 patients. Conclusions: MRI could detect the else changes of bone fracture that can not display by X- ray and CT. Compared with radiography and CT,MRI might be more useful in detection of the else changes of bone fracture and staging of bone fracture.更多还原
