摘　　要：目的采用热层析成像对乳腺表面温度进行不对称分析,探讨乳腺热分布信息与内部疾病的关系,评价热层析成像在乳腺疾病中的诊断价值。资料与方法 179例乳腺疾病患者共222个病灶,均行热层析成像和彩色多普勒超声检查,并经病理结果证实,对比双侧乳腺热图色彩差别并行不对称分析,计算平均温差大小,寻找乳腺良、恶性病变的温差规律。结果 222个乳腺病灶中,恶性病灶95个,炎性病灶8个,其他良性病灶119个;热层析图像显示恶性病灶、良性病灶患侧与对侧乳腺区域平均温差分别为(1.9±0.3)℃、(0.7±0.2)℃,差异有统计学意义(P<0.01);8个炎性病灶患侧与对侧乳腺区域平均温差为(2.0±0.3)℃,与恶性病灶相比,差异无统计学意义(P>0.05)。结论乳腺病灶热分布信息的改变有助于乳腺病灶的检出,热层析成像有望成为乳腺癌的筛查手段之一。Purpose To discuss the relationship between temperature distribution of mammary glands and breast disease by detecting surface temperature change with thermal texture imaging, and to evaluate the value of thermal texture imaging technique in the diagnosis of breast diseases. Materials and Methods A total of 179 patients （222 lesions） with breast diseases confirmed pathologically were examined with ultrasound and thermal texture imaging technique. The asymmetry analysis was conducted on the themaal texture maps of bilateral breasts, and the mean temperature difference was calculated so as to find out the rule to differentiate benign and malignant lesions. Results Among all 222 lesions, 95 were malignant, 119 were benign and 8 were inflammatory masses. The thermal texture maps showed that the mean temperature difference between two breasts was （1.9 ± 0.3）℃ in malignant masses, and it was （0.7±0.2）℃ in benign masses （differences with statistic significance, P〈0.01）. In the 8 cases with inflammatory masses, the mean temperature difference was （2.0±0.3）℃, it showed no statistical difference compared with malignant lesions. Conclusion The temperature change of breast surface is contributory to the detection of breast lesions. Thermal texture maps are promising to be used in the screening of breast cancer.
