探讨CT、MRI在诊断软骨母细胞瘤中的临床应用价值

Study on Clinical Application Value of CT and MRI in Diagnosis of Chondrobla Stoma

目的分析研究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2014年1月—2017年11月到信阳职业技术学院附属医院接受诊治的40例软骨母细胞瘤患者,均应用CT及MRI检查,对比二者在诊断软骨母细胞瘤中的应用价值。结果研究所选40例软骨母细胞瘤患者中,21例(52.50%)为病灶边缘硬化、25例(62.50%)病灶内钙化、9例(22.50%)软组织肿胀、9例(22.50%)骨膜反应、3例(7.50%)关节积液。应用增强扫描可观察到轻度及中度强化。MRI检测:病灶区域呈卵圆形,边界清晰可视,T1W1显示低信号、T2W1混杂信号。其中16例(40.00%)有片状及斑点状钙化,14例(35.00%)出现低信号硬化带,边缘硬化检测不如CT。21例(52.50%)骨髓腔发现水肿信号,较CT更广泛。9例(22.50%)骨膜反应,与CT一致。17例(42.50%)关节腔积液,优于CT。CT及MRI在检测膨胀性改变、骺板穿越及窗格样变化方面差异无统计学意义(P>0.05)。CT在边界清晰及边缘硬化、病灶钙化方面检出率显著高于MRI(P<0.05);CT在骨髓水肿上的检出率明显不如MRI(P<0.05)。结论 CT与MRI在软骨母细胞瘤的检测中均有一定应用价值,CT在检出边界清晰及边缘硬化、病灶钙化方面具有优势,MRI能更有效地检测出骨髓水肿,诊断检测时宜综合使用。

Objective To analyze and study the clinical application value of CT and MRI in diagnosis of chondrobla stoma.Methods 40 cases of patients with chondrobla stoma diagnosed in our hospital from January 2014 to November 2017 were selected and the application value of the two in diagnosis of chondrobla stoma was compared. Results Of 40 cases, there were 21 cases with lesion marginal sclerosis（52.50%）, 25 cases with calcification in the lesion（62.50%）, 9 cases with soft tissue swelling（22.50%）, 9 cases with periosteal reaction（22.50%） and 3 cases with joint effusion（7.50%）, and the mild and moderate enhancement was observed by the enhanced scanning, and the MRI test showed that the lesion region showed the ovary, and the boundary was clear, and the T1 W1 showed the low signal, and the T2 W1 showed the mixed signal, and 16 cases（40.00%）had the flaky and spotted calcification, 14 cases（35.00%） showed the low signal sclerosis band, and the marginal sclerosis test was lower than the CT, and 21 cases（52.50%） showed the edema signal in the bone cavity, wider than CT, and 9 cases（22.50%）had periosteal reaction, consistent with CT, and 17 cases（42.50%）had the arthroedema, better than CT, and there were no obvious differences in the test rate of swelling change, epiphysial disk and pane sample changes between the CT and MRI（P〈0.05）, and the test rate of CT in the clear boundary, border sclerosis and lesion calcification was obviously higher than that of MRI（P〈0.05）, and the test rate of CT in bone marrow edema was obviously lower than that of MRI（P〈0.05）. Conclusion CT and MRI in diagnosis of chondrobla stoma has a certain application value, and the CT is better in diagnosis of clear boundary, border sclerosis and lesion calcification, and the MRI can more effectively test the bone marrow edema, and the two methods can be properly applied in diagnosis.
