乳腺特殊类型恶性肿瘤的融合影像分析

Fusion Image Analysis of Special Types of Breast Malignant Tumor

目的对比分析X线、彩超、MRI及三者联合应用在诊断乳腺特殊类型恶性肿瘤中的价值。方法回顾性分析2013年2月至2020年3月于我院进行的乳腺恶性肿瘤切除术且术后病理证实乳腺特殊类型恶性肿瘤的患者。对比分析了56例的乳腺特殊类型恶性肿瘤患者的术前X线、彩超、MRI及三者联合应用的诊断结果,以此为基础讨论了联合应用三种影像检查手段在诊断乳腺特殊类型恶性肿瘤中的实际应用价值。结果本研究中共诊断56例患者。对比影像结果与病理结果,术前乳腺X线摄影灵敏度为62.5%(20/32),特异度为54.2%(13/24)。超声检查灵敏度为81.1%(30/37),特异度为52.6%(10/19)。MRI灵敏度为92.9%(39/42),特异度为71.4%(10/14)。结论不同检查方法测量结果与病理学之间均存在一定差异。三者联合应用诊断对乳腺特殊类型恶性肿瘤可显著提高其检出率和诊断准确率,效益比明显优于单一检查。

Objective To investigate the diagnostic effect of different imaging techniques on a special type of breast cancer.The utility of X-ray,MRI,and color Doppler ultrasound in the diagnosis of an early special type of breast cancer was compared and analyzed,and the diagnostic experience was summarized.Methods From January 2012 to September 2020,56 patients with a special type of breast cancer were diagnosed by operation and biopsy pathology.they were diagnosed by molybdenum target X-ray,MRI,and color ultrasound(probe frequency 6.5-13.0MHz).Three methods were used to judge breast cancer for comparative analysis to study its clinical medical value.The preoperative X-ray,ultrasound,and magnetic resonance examination results of 56 patients with breast cancer were studied retrospectively,and the imaging data obtained were compared and analyzed.Results A total of 56 patients were diagnosed in this study.Among them,the sensitivity of X-ray photography was(62.5%),the specificity was(54.2%),The sensitivity of ultrasound examination was(81.1%),the specificity was(52.6%),The sensitivity,specificity,of MRI were 92.9%,71.4%,The sensitivity,specificity,and correct rate of combined diagnosis were significantly higher than those of a single diagnosis(P<0.05),while the rate of missed diagnosis and misdiagnosis was significantly lower than that of a single diagnosis(P<0.05).Conclusion There are some differences between the results of different examination methods and pathology,and each method has its limiting factors in practical application.The combined diagnosis of the three can significantly improve the detection rate and diagnostic accuracy of an early special type of breast cancer,and the benefit ratio is significantly better than that of a single examination,which is worthy of wide clinical application.
