摘　　要：目的分析DCE-MRI联合钼靶X线对直径≤2 cm乳腺小结节良恶性的鉴别诊断价值。方法92例直径≤2 cm乳腺小结节患者(92个病灶)均接受DCE-MRI、钼靶X线检查,以病理结果作为金标准,分析DCE-MRI、钼靶X线及二者联合对直径≤2 cm乳腺小结节良恶性的鉴别诊断效能。结果病理诊断结果显示,92例乳腺小结节中恶性结节28例,良性结节64例;DCE-MRI联合钼靶X线鉴别诊断直径≤2 cm乳腺小结节良恶性的灵敏度、准确度、阳性预测值、阴性预测值均高于单独诊断(P<0.05)。结论DCE-MRI联合钼靶X线对直径≤2 cm乳腺小结节良恶性的鉴别诊断效能较高。Objective To analyze the value of DCE-MRI combined with molybdenum target X-ray in the differential diagnosis of benign and malignant small breast nodules with diameter≤2 cm.Methods 92 patients with small breast nodules with diameter≤2 cm(92 lesions)underwent DCE-MRI and molybdenum target X-ray examinations.The pathological results were used as the gold standard to analyze the differential diagnosis efficacy of DCE-MRI,molybdenum target X-ray and their combination for benign and malignant small breast nodules with diameter≤2 cm.Results The results of pathological diagnosis showed that there were 28 cases of malignant nodules and 64 cases of benign nodules in 92 cases of small breast nodules.The sensitivity,accuracy,positive predictive value and negative predictive value of DCE-MRI combined with molybdenum target X-ray in the differential diagnosis of benign and malignant small breast nodules with diameter≤2 cm were higher than those of single diagnosis(P<0.05).Conclusions DCE-MRI combined with molybdenum target X-ray has high efficacy in the differential diagnosis of benign and malignant small breast nodules with diameter≤2 cm.
