摘要
目的:分析磁共振动态增强在早期乳腺癌影响诊断中的应用效果。方法:选取2020年9月至2021年9月于阜宁县人民医院影像科进行检查的106例疑似乳腺癌患者,回顾性分析其临床资料,根据患者病理结果分为乳腺良性病变组(58例)与乳腺癌组(48例),所有患者术前均行磁共振动态增强扫描,观察两组患者影像学特征,对比两组患者的回流速率常数、转运常数、容积分数血流参数。结果:乳腺癌患者病灶形状不规则、毛刺征、血管影增多、强化不均匀、边界模糊占比率高于乳腺良性病变组(P<0.05)。乳腺癌组患者的回流速率常数、转运常数、容积分数明显高于乳腺良性病变组,高度恶性乳腺癌患者的回流速率常数、转运常数、容积分数高于低度恶性乳腺癌患者(P<0.05)。结论:采用磁共振增强扫描可以提高早期乳腺癌检出率,还能借助血流参数定量分析病灶血流特征,为判断病情、评估预后提供参考。
Objective:To analyze the application effect of MR dynamic enhancement in the influence diagnosis of early breast cancer:Methods:Selected in September 2020-106 patients of suspected breast cancer in September 202021,the clinical data,according to the pathological results were divided into benign breast lesion group(58 cases)and breast cancer group(48 cases),all patients preoperative magnetic resonance dynamic enhancement scan,observe the imaging characteristics of two groups,compare the reflux rate constant,transport constant and volume fraction flow parameters of the two groups.Results:In breast cancer patients,irregular shape,burr sign,increased vascular shadow,uneven enhancement,and blurred margins were higher than those in the group with benign breast lesions(P<0.05).The reflux rate constant,transport constant,and volume fraction were significantly higher than those of benign breast lesions,and the reflux rate constant,transport constant,and volume fraction of highly malignant breast cancer patients were higher than those of low-grade malignant breast cancer patients(P<0.05).Conclusion:Magresonance enhanced scanning can improve the detection rate of early breast cancer,and quantitatively analyze the blood flow characteristics with flow parameters to provide reference for judging the condition and prognosis.
