热断层（TTM）技术在乳腺癌鉴别及诊断中的应用 [1] [2] [1] [2] 罗勇 郑延松 李平 郝保云 [1]华西医院, [2]解放军总医院 [摘要]背景和目的：乳腺癌是全世界女性发病率最高的恶性肿瘤在我国乳腺癌已成为城市 女性发病最高的恶性肿瘤。我们利用TTM 检测乳腺包块的女性患者，与术后病检相对照， 探索TTM 在乳腺癌的诊断及与良性包块的鉴别上的价值。设备和方法：设备：1.TSI-2000 型热断层扫描系统；2.TTM V7.0 版专用图像处理系统。方法：1.入组常规检查诊断为乳腺 包块的术前患者；2.收集患者术前病史查体、乳腺彩超、钼靶、及CT 图像资料；3.采集图 像后采用单盲法传至TTM 研发单位进行分析；4.将TTM 结果与临床资料、影像及病检结果 对照，分析得出结论。结果：TTM 在乳腺癌的诊断中灵敏度97.73%，特异度93.75%，阳性 预测率97.73%,诊断符合率96.67% ;对淋巴结的诊断灵敏度92.31%；特异度100%，诊断符 合率94.74%。对淋巴转移灶的诊断符合率100%。结论：1.对乳腺癌与良性病变鉴别及诊断 上有较好的效果。2、在恶性病变淋巴转移的诊断有较大的临床适用价值。3.对良、恶性病 变血供情况判断具有一定意义。 关键词：热断层(TTM);扫描成像; 乳腺良恶性肿瘤 Abstract Background and purpose: Breast cancer is the highest incidence of women around the world of malignant tumor, In our countrys breast cancer has become the highest incidence of female malignant tumor in city,china. We use TTM detection breast masses of female patients,and comparison with postoperation pathology report, Explore the value of TTM in the diagnosis and identification of breast cancer and benign tumor . Equipment and Methods: Equipment: 1 .TSI - 2000 type Thermal Texture Maps System. 2 .TTM V7.0 Image processing system. Methods :1. Patients are routine inspection diagnosis of breast masses of preoperative patients. 2. Collect history ,physical examination, breast colour to exceed, breast X-ray and CT image data. 3. A After collecting image using blind TTM method for image analysis. 4.Will TTM results and clinical data, image and disease inspection results comparison, analysis conclusion. Results: 1.TTM in breast cancer diagnosis of sensitivity = 97.73%, specific degrees = 93.75%, positive prediction rate = 97.73%. Diagnosis coincidence rate =96.67%.2.Lymph nodes diagnosis sensitivity 92.31%; Specific degree 100%, diagnostic coincidence rate 94.74%. Conclusions:1.TTM in the diagnosis and identification of breast canc
