摘要
目的探讨乳腺三算子及血氧功能成像技术在乳腺癌诊断中的应用价值。方法对146例患有乳腺疾病的妇女行体格检查、三算子及血氧功能成像，超声和（或）乳腺X线检查。共发现153个病灶。在这些病灶中，四项检查中至少有一项提示需要接受手术，通过与术后病理对比，得出各自影像学诊断的准确性。结果146例中61例为恶性。超声检查的敏感性为80．33％，特异性为89．41％，准确性为85．61％，阳性预测值84．48％，阴性预测值86．36％。乳腺x线检查的敏感性为57．89％，特异性为80．36％，准确性为69．03％，阳性预测值75．00％，阴性预测值65．22％。三算子及血氧功能成像检查的敏感性为91．80％，特异性为83．53％，准确性为86．99％，阳性预测值80．00％，阴性预测值94．67％。结论三算子及血氧功能成像检查对乳腺病灶诊断的敏感性、准确性、阴性预测值均优于乳腺X线检查和超声检查，特异性和阳性预测值介于两者之间，对乳腺癌的筛查及诊断有较大应用价值。
Objective To evaluate thri-operators and the blood-oxygen functional image technology in diagnosing breast cancer. Methods One hundred and forty-six patients were admitted to hospital for operation due to one hundred and fifty-three suspicious lesions detected in their breasts. These lesions were detected by physical examination, thri-operators and the blood-oxygen functional image, mammography uhrasonography. The sensitivity and specificity of each diagnostic method were obtained and the radiologic-pathologie correlation was meanwhile calculated. Results Sixty one（41.8% ）breast lesions were diagnosed as malignancy. The sensitivity, specificity, accuracy,positive prognostic value and negative prognostic value of ultras onography were 80. 33%, 89.41%, 85.61%, 84. 48% and 86. 36%. Such data of mammography were 57. 89%, 80. 36%, 69. 03%, 75. 00% and 65.22%. And those of thri-operators and the blood-oxygen functional image technology were 91.80% ,83.53% , 86.99% ,80.00% and 94.67%. Conclusions Thri-operators and the blood-oxygen functional image technology is superior to uhrasonography and mammography in diagnosing breast lesions with its sensitivity accuracy and negative prognostic value, while specificity and positive prognostic value were between them, have greater value in screeninging and the diagnosing breast cancer.
