多层螺旋CT多期增强扫描对肺癌多发骨转移的诊断价值

Value of Multislice CT Multiphase Enhancement Scanning in Diagnosis of Patients with Multiple Bony Metastasis of Lung Cancer

目的旨在探讨多层螺旋CT(MSCT)多期增强扫描对肺癌多发骨转移的诊断价值。方法收集2015年7月—2016年12月收治的78例肺癌多发骨转移患者的临床资料,均进行了MSCT平扫及多期增强扫描,将MSCT平扫及多期增强扫描对肺癌多发骨转移检出率与正电子发射计算机断层显像(PET-CT)检查结果进行对比,分析MSCT多期增强扫描对肺癌多发骨转移的诊断价值。结果 78例患者PET-CT扫描共发现骨转移病灶181个,分别为椎体转移62个,肋骨等附件转移52个,股骨转移34个,肩胛骨转移29个,颅骨转移4个。MSCT平扫对肺癌骨转移检出率为78.45%(142/181),MSCT多期增强扫描对肺癌骨转移检出率为95.58%(173/181)。CT平扫对肺癌骨转移椎体转移检出率、肩胛骨转移检出率及总检出率明显低于MSCT多期增强扫描(P<0.01)。结论 MSCT多期增强扫描对肺癌多发骨转移检出率高,可为临床制定治疗方案提供影像资料。

Objective To investigate value of multislice CT （MSCT） multiphase enhancement scanning in diag- nosis of patients with multiple bony metastasis of lung cancer. Methods Clinical data of 78 patients with multiple bony metastasis of lung cancer during July 2015 and December 2016 was collected. All patients underwent MSCT plain scan- ning and multiphase enhancement scanning, Dectection rates of plain scanning and multiphase enhancement scanning for multiple bony metastases of lung cancer were compared with the results by positron emission tomography-computed tomo- graphy （PET-CT） examination, and the value of MSCT multiphase enhancement scanning in diagnosis of patients with multiple bony metastasis of lung cancer was analyzed. Results A total of 181 metastatic bone lesions were found in 78 patients with lung cancer by PET-CT examination, which included 62 cases of vertebral metastasis, 52 cases of ribs and other accessories metastasis, 34 of femoral metastasis, 29 eases of scapular bony metastasis and 4 cases of skull metasta- sis. Detection rates for bony metastasis of lung cancer were 78.45% （142/181） by MSCT plain scanning and 95.58% （ 173/181 ） by MSCT multiphase enhancement scanning respectively. Detection rates of vertebral body and scapula me- tastasis and the total detection rate by CT plain scanning were significantly lower than those by MSCT multiphase enhance- ment scanning （P 〈 0. 01 ）. Conclusion MSCT muhiphase enhancement scanning has high detection rate in diagnosis of patients with multiple bony metastasis of lung cancer, and it may provide imaging data for clinical treatment.
