目的评价胸部MRI在肺癌肋骨转移检测的价值,尤其在术前的检测价值。方法回顾性搜集54例在本院行全身骨显像、胸部CT和胸部MRI三项检查并经病理组织学和/或细胞学证实为肺癌的患者资料,比较三项影像学检查对肋骨转移病例和病灶检出的敏感性、特异性和准确性,并采用χ2检验。结果 54例中,有30例患者(120个病灶)确诊为多发性肋骨转移。MRI与CT、骨显像间对病灶检出的敏感性和准确性有统计学差异(χ2=14.294,P=0.001;χ2=15.181,P=0.001;均P<0.05)。结论 MRI对肺癌肋骨转移的检出优于CT和骨显像,MRI对肺癌肋骨转移的筛查、监测、临床诊断尤其是术前诊断具有肯定的临床价值。
Objective To evaluate the value of chest MRI in the detection of rib metastases in lung cancer, especially in preoperative detection. Methods The data of 54 patients who underwent bone imaging, thoracic CT and thoracic MRI in our hospital were retrospectively collected. The histopathological and / or cytological findings of lung cancer were retrospectively analyzed. Three cases of rib metastasis were compared And lesion detection sensitivity, specificity and accuracy, and using χ2 test. Results Of the 54 patients, 30 (120 lesions) were diagnosed with multiple rib metastases. The sensitivity and accuracy of MRI, CT and bone imaging were statistically different (χ2 = 14.294, P = 0.001; χ2 = 15.181, P = 0.001; all P <0.05). Conclusion MRI is superior to CT and bone imaging in the detection of rib metastases of lung cancer. MRI has certain clinical value in screening, monitoring, clinical diagnosis, especially preoperative diagnosis of lung cancer.
