| 摘 要： | 目的评价增强ＭＲＩ对乳腺良、恶性病变的诊断价值。方法对４８例乳腺病变患者进行ＭＲＩ平扫和增强扫描，并对照Ｘ线、Ｂ超及手术病理结果，分析比较了病变强化后形状、边界、内部信号、强化速度与程度以及强化消失快慢等特征。结果４８例乳腺病变患者８１个病灶的良、恶性诊断准确率为９２．６％。结论增强ＭＲＩ是鉴别乳腺良、恶性病变的一种有效的影像学诊断方法

| Abstract: | Purpose To evaluate the diagnostic value of contrast enhanced MRI for benign and malignant breast lesions. Methods 48 patients were scanned by conventional MRI and contrast enhanced MRI,all cases had of X ray,B ultrasound,surgery and pathologic examiantions. The authors analysed some characteristics of benign and malignant lesions after administration of Gd DTPA,such as,shape,border,signal intensity, degree of enhancement , speed of enhancement and washout,and so on. Results Correct diagnostic rate of 81 lesions in 48 patients with breast diseases for benign and malignant was 92.6%. Conclusion Contrast enhanced MRI is a new effective medical imaging method for differientiating benign and malignant breast lesions. |
