摘要:
目的 分析1.5T磁共振成像（MRI）与乳腺X线摄影在乳腺良恶性肿瘤诊断中的应用价值与特征。方法 选取2014年1月-2020年12月于我院就诊的75例乳腺病变患者，分别给予1.5T MRI检查与乳腺X线摄影检查，比较两种检查方式的影像学特征，并以病理学检查为金标准，比较1.5T MRI与乳腺X线摄影的正确诊断率、过度诊断率、漏诊率，分析其在乳腺良恶性肿瘤诊断中的诊断效能（灵敏度、特异度、准确性）。结果 MRI表现中，良、恶性乳腺病灶的部位、形态及边界特征比较，差异有统计学意义（P＜0.05）；乳腺X线表现中，良、恶性乳腺病灶的边界、形态及间接征象对比，差异有统计学意义（P＜0.05）；MRI对乳腺良恶性病变的正确诊断率高于乳腺X线摄影检查，而过度诊断率与漏诊率低于乳腺X线摄影检查，联合诊断乳腺良恶性病变的正确诊断率高于单一的MRI及X线摄影，差异有统计学意义（P＜0.05）。MRI对乳腺良恶性病变的诊断灵敏度、特异度及准确性均高于乳腺X线摄影诊断，而联合诊断乳腺良恶性病变的诊断灵敏度、特异度及准确性均高于单一MRI及X线摄影，差异有统计学意义（P＜0.05）。结论 1.5T MRI对乳腺良恶性病变的诊断定性能力高于乳腺X线摄影，二者在影像学表现方面存在一定的共性与差异，乳腺X线摄影对钙化等征象的检出率较高，而1.5T MRI则具有更高的诊断准确性。
Abstract:
Objective To analyze the application value and characteristics of 1.5T magnetic resonance imaging (MRI) and mammography in the diagnosis of benign and malignant breast tumors.Methods A total of 75 patients with breast lesions who were treated in our hospital from January 2014 to December 2020 were selected and given 1.5T MRI and mammography respectively. The imaging characteristics of the two methods were compared, and pathological examination was used as the gold standard, the correct diagnosis rate, excessive diagnosis rate and missed diagnosis rate of 1.5T MRI and mammography were compared, and the diagnostic efficacy (sensitivity, specificity and accuracy) in the diagnosis of benign and malignant breast tumors was analyzed.Results In MRI, the location, morphology and boundary characteristics of benign and malignant breast lesions were statistically significant (P<0.05). In the breast X-ray manifestations, the boundary, morphology and indirect signs of benign and malignant breast lesions were compared, and the difference was statistically significant (P<0.05). The correct diagnosis rate of MRI for benign and malignant breast lesions was higher than that of mammography, while the overdiagnosis rate and missed diagnosis rate were lower than those of mammography, the correct diagnosis rate of combined diagnosis of benign and malignant breast lesions was higher than that of single MRI and mammography, and the difference was statistically significant (P<0.05). The sensitivity, specificity and accuracy of MRI in the diagnosis of benign and malignant breast lesions were higher than those of mammography, and the sensitivity, specificity and accuracy of combined diagnosis of benign and malignant breast lesions were higher than those of single MRI and X-ray photography, the difference was statistically significant (P<0.05).Conclusion 1.5T MRI is superior to mammography in the diagnosis of benign and malignant breast lesions. There are some similarities and differences in imaging findings between the two, mammography has a higher detection rate of calcification and other signs, while 1.5 T MRI has higher diagnostic accuracy.
