中文摘要：目的:探讨与分析定量动态增强核磁共振成像(MRI)对骨肿瘤的诊断价值。方法:选取2021年4月—2023年1月我院收治的 72例骨肿瘤患者中为研究对象。经病理检查证实，所有患者都给予定量动态增强MRI检查，记录成像特征。以病理检查为诊断的金标准，判断定量动态增强MRI的诊断价值。结果:在 72例患者中，病理诊断为良性肿瘤 40例，恶性肿瘤 32例，2组的性别、年龄、体重指数、骨肿瘤位置、收缩压、舒张压对比，组间差异无统计学意义(P>0。05)。恶性肿瘤组的核磁共振成像骨质破坏、骨质边缘模糊、钙化、肢体受累占比分别为78。1%、93。8%、81。3%、90。6%，均高于良性肿瘤组的 35。0%、47。5%、40。0%、35。0%，组间差异有统计学意义(P<0。05)。恶性肿瘤组的核磁共振成像T 1WI序列、T 2WI序列低信号占比分别为 78。1%、81。3%，均高于良性肿瘤组的 47。5%、50。0%，组间差异有统计学意义(P<0。05)。恶性肿瘤组的定量动态增强核磁共振成像参数-血管外细胞外间隙容积分数、容量转运常数、速率常数均高于良性肿瘤组，组间差异有统计学意义(P<0。05)。在 72例患者中，定量动态增强MRI判断为恶性肿瘤 31例，良性肿瘤 41例，定量动态增强MRI对骨肿瘤良恶性的鉴别诊断敏感性与特异性分别为96。7%、92。9%。结论:恶性骨肿瘤患者在核磁共振成像中多伴随有骨功能下降，且多呈现低信号，伴随有定量动态增强参数的异常，定量动态增强MRI对骨肿瘤良恶性的鉴别诊断敏感性与特异性都比较高。

外文标题：Diagnostic Value of Quantitative Dynamic Enhanced MRI in Bone Tumors

外文摘要：Objective:To explore and analyze the diagnostic value of quantitative dynamic enhanced magnetic resonance imaging(MRI)in bone tumors.Methods:72 patients with bone tumor admitted to our hospital from April 2021 to January 2023 were selected as the study objects.It was confirmed by pathological examination that all patients were given quantitative dynamic enhanced MRI to record the imaging characteristics.The diagnostic value of quantitative dynamic enhanced MRI was evaluated with pathological examination as the gold standard.Results:Among the 72 patients,40 were pathologically diagnosed as benign tumors and 32 as malignant tumors.There was no significant difference between the two groups in gender,age,body mass index,location of bone tumors,systolic blood pressure and diastolic blood pressure(P>0.05).The proportions of bone destruction,bone margin blur,calcification and limb involvement on MRI in the malignant tumor group were 78.1%,93.8%,81.3% and 90.6%,respectively,which were higher than 35.0%,47.5%,40.0% and 35.0% in the benign tumor group,and the differences between groups were statistically significant(P<0.05).The low signal ratio of T1WI and T2WI sequences in the malignant tumor group was 78.1% and 81.3%,respectively,which were higher than 47.5% and 50.0% of the benign tumor group(P<0.05).The quantitative dynamic enhanced MRI parameters,such as extracellular space volume fraction,volume transport constant and rate constant,in the malignant tumor group were higher than those in the benign tumor group,and the differences between groups were statistically significant(P<0.05).Among the 72 patients,31 cases were malignant tumors and 41 cases were benign tumors.The sensitivity and specificity of quantitative dynamic enhanced MRI for differential diagnosis of benign and malignant bone tumors were 96.7% and 92.9% .Conclusion:Patients with malignant bone tumors are mostly accompanied by decreased bone function and low signal in MRI,accompanied by abnormal quantitative dynamic enhancement parameters.Quantitative dynamic enhancement MRI has high sensitivity and specificity in the differential diagnosis of benign and malignant bone tumors.
