摘要
目的探究磁共振成像(MRI)与多层螺旋CT(MSCT)动态增强在乳腺癌及其远隔转移情况的诊断价值。方法回顾性分析184例乳腺包块患者临床及影像学资料,比较MRI动态增强和MSCT动态增强诊断乳腺癌及其远隔转移结果,并与穿刺活检的病例结果相比较,评估两种动态增强在诊断乳腺癌及其远隔转移方面的各自优势。结果 184例乳腺包块患者经穿刺活检证实为乳腺癌113例,乳腺良性病变71例。MRI动态增强共诊断准确179例(97.28%),Kappa值0.931,一致性极强;MSCT动态增强共诊断准确145例(78.80%),Kappa值为0.541,一致性中度。MRI动态增强诊断的灵敏度、特异度、阳性预测值、阴性预测值、准确率均高于MSCT动态增强(P<0.05)。在113例乳腺癌患者中,远隔转移共17例;MRI动态增强诊断4例(23.53%),MSCT动态增强诊断17例(100.00%);MRI动态增强诊断乳腺癌远隔转移准确率低于MSCT动态增强(P<0.05)。结论 MRI与MSCT动态增强对乳腺癌及其远隔转移诊断,MRI对肿瘤定性诊断价值更高,MSCT对远隔转移诊断更优,两种检查方法互补性强。
Objective To explore the diagnostic value of magnetic resonance imaging(MRI)and multi-slice computed tomography(MSCT)dynamic enhancement in the diagnosis of breast cancer and its distant metastases.Methods The clinical and imaging data of 184 patients with breast masses were retrospectively analyzed.The results of MRI dynamic enhancement and MSCT dynamic enhancement were compared in the diagnosis of breast cancer and its distant metastases and were compared with results of needle biopsy.The adva ntages of the two examination methods in diagnosing breast cancer and its distant metastases were evaluated.Results Among184 patients with breast masses,there were113 cases of breast cancer and 71 cases of benign breast lesions confirmed by needle biopsy.179 patients(97.28%)were accurately diagnosed by MRI dynamic enhancement,and the Kappa value was 0.931,with strongly high consistency.145 patients(78.80%)were accurately diagnosed by MSCT dynamic enhancement,and the Kappa value was 0.541,with moderate consistency.The sensitivity,specificity,positive predictive value,negative predictive value,and accuracy rate of MRI dynamic enhancement diagnosis were higher than MSCT dynamic enhancement(P<0.05).Among 113 cases of breast cancer,there were a total of 17 distant metastases,and 4 vases(23.53%)were accurately diagnosed by MRI dynamic enhancement,and 17 cases(100.00%)were accurately diagnosed by MSCT dynamic enhancement.The accuracy rate of MRI dynamic enhancement was lower than that in MSCT dynamic enhancement in diagnosing distant metastases of breast cancer(P>0.05).Conclusion MRI and MSCT dynamic enhancement have higher diagnostic value in diagnosing breast cancer and its distant metastases.MRI has a higher diagnostic value for the qualitative diagnosis of tumors,and MSCT has a higher diagnostic value for distant metastases,and both methods have complementa rity.
