摘要

目的：

评价最大标准化摄取值(maximum standardized uptake value，SUVmax)在肿瘤患者肋骨转移病灶诊断中的价值。

方法：

选取2016年5月2016年11月于同济大学附属东方医院核医学科行SPECT/CT融合显像并经随访明确诊断为肿瘤肋骨转移的21例患者共42个病灶，以及明确诊断为肋骨损伤性病变的12例患者22个病灶，病灶对侧的正常肋骨作为对照，测定SUVmax，采用t检验和受试者工作特征(receiver operating characteristic，ROC)曲线进行分析。

结果：

转移组SUVmax平均值为24.05(SD=11.84)，对照组为5.25(SD=1.63)，损伤组为13.71(SD=5.61)，三组之间比较有统计学差异。肋骨病变(转移、损伤)的ROC曲线下面积为0.990，最佳诊断阈值为7.96，灵敏度为95%；肋骨病变中，肋骨转移的ROC曲线下面积为0.808，阈值为20.45时其灵敏度为57%，特异度为91%。

结论：

SPECT/CT融合显像中SUVmax值可作为肿瘤肋骨转移的辅助诊断依据。

Abstract

Objective：

To evaluate the value of maximum standardized uptake value (SUVmax) in the diagnosis of rib metastasis.

Methods:

From May 2016 to November 2016

SPECT/CT fusion imaging and follow-up diagnosis of rib metastasis were performed in 21 patients with 42 rib metastasis lesions and 12 patients with 22 rib injury lesions. The contralateral normal ribs were used as controls

and SUVmax values were measured. t-test and receiver operating characteristic (ROC) curve analyses were performed.

Results:

The mean SUVmax was 24.05 (SD=11.84) in the metastasis group

13.71 (

SD=5.61) in the injury group

and 5.25 (SD=1.63) in the control group. There were significant differences among three groups (P0.001). The area under the ROC curve was 0.990 and the cutoff value was 7.96 when SUVmax was used to diagnose rib lesions. But the area under the ROC curve was 0.808 and the cutoff value was 20.45 when SUVmax was used to diagnose rib metastasis.

Conclusion:

SUVmax is more valuable in SPECT/CT fusion imaging for the diagnosis of rib metastasis.
