摘　　要：目的探讨3.0T磁共振联合乳腺磁共振计算机辅助系统(MRI-CAD)在良、恶性乳腺肿瘤鉴别诊断中的价值。方法分别利用3.0TMRI工作站(MRI法)和MRI-CAD(CAD法)对78例患者共93个乳腺病灶进行良、恶性鉴别诊断,内容包括形态学分析和时间信号曲线分析,比较两种方法的诊断正确率。结果在93个病灶中CAD法诊断正确率高于MRI法,差异有统计学意义(P<0.05);MRI法和CAD法在51例肿块样病变中诊断正确率差异无统计学意义(P>0.05);CAD法在42例非肿块样病变中诊断正确率高于MRI法,差异有统计学意义(P<0.05)。结论 MRI-CAD与利用MRI工作站比较,在良、恶性乳腺肿瘤特别是非肿块样病灶的鉴别诊断中具有明显优势。Objective To explore the clinical value of 3.0Tesla magnetic resonance imaging（MRI） combined with computer aided diagnosis（MRI-CAD） in differentiating benign and malignant breast tumors.Methods MRI and MRI-CAD were used in the diagnosis of a total of 93 breast lesions from 78 patients,including morphological and time-intensity-curve analysis.Accuracies of the two methods were compared.Results MRI-CAD had a statistically better accuracy than MRI（P0.05）.For 51 mass-like lesions,MRI and MRI-CAD had no difference in diagnostic accuracy（P0.05）,while for 42 non-mass-like lesions,MRI-CAD was statistically better（P0.05）.Conclusion MRI-CAD has a notable advantage over MRI in differential diagnosis of benign and malignant breast tumors,especially non-mass-like tumors.
