SPECT核素骨显像联合MRI增强成像鉴别诊断骨转移瘤100例临床观察

目的评估SPECT核素骨显像（以下简称ECT）联合磁共振（MRI）增强成像检查鉴别及确诊骨转移瘤的价值，并探讨两者检查的优劣势，以便优势互补，提高诊断率。方法选择100例先行骨显像后行MRI增强检查的患者，分别阅读各自发现的病灶，再两者对比阅读发现的病灶，甚至随访直到确诊。验证两者结合检查对提高诊断率的可行性。结果ECT核素骨显像的准确性93％，MRI的准确性为99％，两者比较，差异有统计学意义（P〈0．05）。结论联合应用ECT及MRI增强成像检查，可以提高骨转移瘤的早期诊断率及鉴别诊断。

Clinical Observation on Diagnosing and Differentiating Bone Metastases in 100 Cases by SPECT Bone Imaging Combined with CE- MRI

Objective To evaluate the value of SPECT Radionuclide Bone Imaging （ECT） combined with Contrast Enhancement Magnetic Resonance Imaging（ CE-MRI） in diagnosing and differentiating bone metastases. Methods 100 patients were first checked by radionuclide bone imaging and contrast enhanced MRI. The patients were then followed until the metastases were confirmed. The results of the bone imaging and MRI were compared independently to the clinical results. Results The accuracy of ECT and CE - MRI was 93% and 99% , respectively, and the differences were statistically significant （ P 〈 0.05 ）. Conclusion The combination of ECT and CE - MRI may improve the accuracy of diagnosis and differentiation of early bone metastases.
