摘　　要：目的 :参照X线摄影在乳腺疾病诊断方面的特点 ,评价用螺旋CT扫描乳腺技术的诊断价值。方法 :将外科手术证实的 15 6例乳腺疾病患者分为乳腺癌组和非乳腺癌组 ,观察X线摄影和螺旋CT扫描对乳腺良恶性疾病诊断的准确性 ,并比较各自的优缺点。结果 :15 6例有乳腺肿块的患者中 ,经手术和病理证实乳腺癌 65例 ,乳腺良性疾病 91例。 65例乳腺癌中有 10例乳腺X线摄影检查为阴性 ,其中 4例因腺体致密而不能确诊。这 4例中螺旋CT检出 2例阳性病变。乳腺X线摄影诊断的敏感性和特异性分别为 84.6%和 83 .5 % ,螺旋CT扫描为 83 .1%和 76.9%。乳腺X线摄影和螺旋CT扫描的阳性预测值分别为 78.6%和 72 .0 % ,其阴性预测值为 88.4%和 86.4%。结论 :对于乳腺良恶性肿瘤的检查 ,首选乳腺X线 ,必要时CT可作为补充。Objective:To assess the diagnostic accuracy of spiral CT (SCT) scanning as compared with that of mammography.Methods:156 patients had been examined by both mammography and SCT scanning before surgery.The patients were divided into two groups:cancer and non cancer.The diagnostic accuracy of these two modalities were calculated. Results: Of 156 patients,65 had breast cancer and 91 had benign lesions.The sensitivity and specificity for mammography were 84.6% and 83.5% respectively,and 83.1% and 76.9% for SCT scanning.The positive predictive values for mammography and SCT scanning were 78.6% and 72.0% respectively;the negative predictive values for these two modalities were 88.4% and 86.4%.Conclusion:SCT scanning,as an adjunct to mammography,can enhance sensitivity and predictive value of positivity in detecting breast cancer,especially in radiographically dense breast.
