RESUMEN
OBJECTIVE: To determine the clinical value of breast thermal tomography and high frequency ultrasound imaging in diagnosing breast cancer. METHODS: Breast thermal tomography and high frequency ultrasound imaging were performed in 298 patients with breast lumps. The results were compared with pathological diagnosis. RESULTS: The ultrasound imaging had a sensitivity, specificity and the area under the curve (AUC) of 99.02%, 62.78% and 0.814, respectively, compared with 83.33%, 83.16% and 0.830 of thermal tomography, for diagnosing breast cancer. The two imaging results showed statistical significance in the test of non-inferiority (P < 0.001). A combination of the two imaging results produced a sensitivity, specificity and AUC of 83.33%, 89.79% and 0.866, respectively. CONCLUSION: Thermal tomography is not inferior to ultrasonography in detecting breast cancer. The two combined can improve specificity and accuracy of the diagnosis of breast cancer.
