目的探讨X线和CT扫描对诊断成软骨细胞瘤的价值。方法选择2007年6月~2013年12月江门市第三人民医院收治的46例成软骨细胞瘤患者作为观察对象。将X线检查的结果设为X线组,而CT检查结果设为CT组,比较两种影像检查方法的结果差异。结果患者术后经病理确诊成骨细胞瘤阳性42例,阴性4例。X线检查阳性38例,阴性8例。其中2例误诊为阴性,6例误诊为阳性。X线检查的敏感性为91.9%(34/37).X线检查特异性为11.1%(1/9);CT检查阳性45例,阴性1例。其中3例误诊为阴性。CT检查的敏感性为93.3%(42/45)。CT检查特异性为100.0%(1/1);CT检查敏感性为93.3%稍高于X线检查91.9%,比较无统计学差异(P>0.05)。而CT检查特异性为100.0%显著高于X线检查11.1%,比较有统计学差异(χ2=4.44,P<0.05)。结论 X线及CT扫描对诊断成软骨细胞瘤具有较高的诊断敏感性。但CT检查较X线具有更高的诊断特异性。临床应结合两者的诊断优势对该病进行鉴别诊断,值得临床选择。
Objective To investigate the value of X-ray and CT scan in the diagnosis of chondroblastoma. Methods From June 2007 to December 2013, 46 patients with chondroblastoma admitted to the Third People’s Hospital of Jiangmen City were selected as observation subjects. The result of the X-ray examination was set as the X-ray group, and the CT examination result was set as the CT group, and the difference between the results of the two image examination methods was compared. Results The patients were pathologically confirmed 42 cases of osteoblast tumors, negative in 4 cases. X-ray examination positive 38 cases, negative in 8 cases. Two of them were misdiagnosed as negative and 6 were misdiagnosed as positive. The sensitivity of X-ray examination was 91.9% (34/37), the specificity of X-ray examination was 11.1% (1/9), the positive of CT examination was 45 cases and the negative was 1 case. Three of them were misdiagnosed as negative. The sensitivity of CT examination was 93.3% (42/45). The specificity of CT examination was 100.0% (1/1). The sensitivity of CT examination was 93.3%, which was slightly higher than that of X-ray examination (91.9%). There was no significant difference (P> 0.05). The specificity of CT examination was 100.0%, which was significantly higher than that of X-ray examination (11.1%) (χ2 = 4.44, P <0.05). Conclusion X-ray and CT scan have high diagnostic sensitivity to diagnosis of chondroblastoma. But CT examination has higher diagnostic specificity than X-ray. Clinical diagnosis should be combined with the advantages of both the differential diagnosis of the disease, it is worth the clinical choice.
