原发动脉瘤样骨囊肿的CT和MRI表现与诊断价值

Diagnosis Value and Findings of CT and MRI in Primary Aneurysmal Bone Cyst

目的探讨CT检查和MRI检查原发动脉瘤样骨囊肿表现和诊断价值差异。方法整群选取于2011年1月—2015年1月来院治疗的原发动脉瘤样骨囊肿52例作为研究对象,均经手术病理证实,并行CT检查和MRI检查,比较两种影像学检查方法影像学表现及诊断准确率。结果该组患者中CT诊断准确率为90.38%,MRI诊断准确率为94.23%,两种诊断准确率比较差异无统计学意义(P>0.05);CT检查和MRI检查诊断囊腔数目、液-液平面及病理骨折等方面比较差异有统计学意义(P<0.05)。结论 CT检查和MRI检查方法在原发动脉瘤样骨囊肿诊断方面均具有良好的临床价值;但MRI检查在诊断微小病变方面具有更高敏感性。

Objective To investigate the difference of diagnosis value and findings of CT and MRI in primary aneurysmal bone cyst. Methods 52 cases of primary tumor bone cyst treated in our hospital from January 2011 to January were selected as the research object, and were confirmed by operation and pathology. The imaging features and diagnostic accuracy of CT and MRI were compared. Results The diagnostic accuracy of MRI was 90.38%, the accuracy of CT was 94.23%, and the difference was statistically significant(P>0.05). The difference was statistically significant(P<0.05). CT and MRI were significantly different in the diagnosis of capsule cavity number, the liquid- liquid plane and the pathological fracture, and the difference was statistically significant(P<0.05). Conclusion CT and MRI have good clinical value in the diagnosis of primary tumor bone cyst, but MRI examination has a higher sensitivity in the diagnosis of small lesions.
