①目的探讨核素骨显像与Ｘ线平片对肺癌骨转移的诊断价值。②方法对８２例肺癌病人分别进行９９ｍＴｃ－ＭＤＰ骨显像及Ｘ线平片检查。③结果核素骨显像阳性者５５例（６０．０７％），检出骨转移病灶１２４个；骨Ｘ线平片阳性者３４例（４１．４６％），检出骨转移病灶４９个。两种方法阳性检出率相比较差异有显著性（χ２＝９．９１，Ｐ＜０．０１）。在３４例骨Ｘ线平片阳性者中，有４例骨显像为阴性，示骨显像假阴性为１１．７６％．对２１例骨显像阳性而Ｘ线平片阴性病人的随访结果表明，从骨显像阳性至骨Ｘ线平片示该部位骨质异常改变的最早期限为９６ｄ，最迟为２４０ｄ，中位数为１３５ｄ．④结论骨显像有早期诊断肺癌骨转移灶的价值。两种方法结合应用对肺癌骨转移的诊断有互补作用，可以提高诊断率。
Objective To investigate the value of radionuclide bone imaging and X-ray plain film in the diagnosis of bone metastasis of lung cancer. 2 Methods 82mTc-MDP bone scans and X-rays were performed on 82 patients with lung cancer. 3 Results Radionuclide bone imaging in 55 cases (60.07%), detected bone metastases 124; 34 cases of bone X-ray positive (41.46%), detected 49 cases of bone metastases. There was a significant difference in the positive detection rate between the two methods (χ2=9.91, P<0.01). In 34 cases of bone X-ray positive, there were 4 cases of bone imaging was negative, showing bone false negative was 11.76%. The follow-up results of 21 cases with positive bone imaging and negative X-ray film showed that the earliest period of bone abnormality change from bone imaging to bone radiography was 96 days, and the latest was 240 days. The number is 135d. 4 Conclusions Bone scintigraphy has the value of early diagnosis of bone metastases in lung cancer. The combination of the two methods has a complementary effect on the diagnosis of bone metastases in lung cancer and can improve the diagnostic rate.
