X线平片和CT诊断骨样骨瘤的能力:64层CT后处理的价值

目的:分析骨样骨瘤的X线和CT表现,探讨64层CT对骨样骨瘤的诊断价值.方法:经手术病理证实的骨样骨瘤19例,男13例,女6例,年龄12～44岁,平均21.5岁.所有病例均行X线检查,同时行CT检查者12例,其中行64层CT检查者4例.分析骨样骨瘤的X线和CT表现,分析2种检查方法对瘤巢和瘤巢周围改变的显示能力.结果:19例病灶均表现为一圆形或卵圆形透亮区,直径0.4～1.7cm(平均10.2cm),其周围有不同程度的骨质硬化,5例周围软组织肿胀.19例中X线平片显示瘤巢14例,12例行CT检查者均清楚显示瘤巢,X线和CT对瘤巢的显示率分别为73.7% (14/19)和100% (12/12).结论:X线平片是诊断骨样骨瘤的重要检查方法,64层CT结合其后处理技术对发现瘤巢和正确诊断骨样骨瘤有重要价值.

Efficacy of Radiography and CT in the Diagnosis of Osteoid Osteoma:Value of Post-processing Techniques with 64-slice Spiral CT

Objective:To analyze the radiography and CT manifestations and to discuss the value of 64-slice spiral CT (MSCT) in the diagnosis of osteoid osteoma.Methods:Nineteen cases of osteoid osteoma proved by surgery and pathology were collected,including 13 males and 6 females,with the age ranged from 12 to 44 years,the average age was 21.5 years.All of the 19 patients were examined by X-ray plain films and 12 patients had CT scanning,including 4 cases had MSCT.The radiographic and CT findings and the ability of t...
