CT、MRI在诊断软骨母细胞瘤中的临床价值

Clinical Value of CT and MRI in the Diagnosis of Chondroblastoma

目的探讨CT、MRI在诊断软骨母细胞瘤中的临床应用价值。方法回顾性分析2009年1月~2015年2月我院收治的20例软骨母细胞瘤患者的临床资料,患者均行CT及MRI检查,比较两种诊断方式对软骨母细胞瘤的临床诊断价值。结果 CT和MRI检查软骨母细胞瘤的临床特征各具特征性。CT与MRI对膨胀性病变和软骨母细胞瘤的准确诊断率相较无明显差异(P>0.05);但CT对边界清晰伴边缘硬化(80.00%vs.50.00%)、病灶内钙化检出率(75.00%vs.35.00%)显著高于MRI的检出率。关节积液(5.00%vs.50.00%)、骨膜水肿(0 vs.85.00%)及瘤周围水肿(0 vs.20.00%)的检出率,差异有统计学意义(均P<0.05)。结论 CT、MRI在诊断软骨母细胞瘤诊断中各具优势,CT在软骨母细胞瘤的边界清晰伴边缘硬化及病灶内钙化诊断更具优势,而MRI在软骨母细胞瘤的关节积液及骨膜水肿的诊断中更具优势,而联合应用两种技术利于提高软骨母细胞瘤的准确诊断率。

Objective To investigate the clinical value of CT and MRI in the diagnosis of neuroblastoma. Methods The clinical data of 20 patients with chondroblastoma treated in our hospital from January 2009 to February 2015 were retrospectively analyzed. All patients were examined with CT and MRI. The clinical value of these two methods in the diagnosis of chondroblastoma was compared. Results The clinical features of chondroblastoma detected by CT and MRI were different. The detection rate of expanding lesions and the accuracy in the diagnosis of chondroblastoma showed no statistically significant difference between CT and MRI （P〉0.05）. The detection rates of clear boundary with marginal sclerosis （80.00% vs. 50.00%） and calcification within the lesions （75.00% vs. 35.00%） by CT were significantly higher than those by MRI. While the detection rates of joint effusion （5.00% vs. 50.00%）, periosteal edema （0 vs. 85.00%） and peritumoral edema （0 vs. 20.00%） were lower than those by MRI （P〈0.05）. Conclusion CT and MRI have their own advantages in the diagnosis of chondroblastoma. CT has more advantages in the diagnosis of clear boundary with marginal sclerosis and calcification, while MRI has more advantages in the diagnosis of joint effusion and periosteal edema. The combined use of these two methods can improve the accuracy rate of diagnosis of chondroblastoma.
