Abstract:
Objective To explore the value of diffused optical tomography(DOT)with ultrasonography (US)in differential diagnosis of breast benign from malignant neoplasms.Methods One hundred ard twenty-three breast neoplasms from 113 patients were checked use the optical tomography image ultrasonography(OPTIMUS).The diagnosis results of the system were compared with pathological study.Two-dimensional ultrasound features in breast neoplasms were digitalizated,and HBT and SO_2 were detected by DOT.At last,synthesis diagnostic index(SDI)was obtained by both US and DOT.Statistic process was carried out in sensitivity,specificity,and the rate of accuracy respectively by US,DOT and OPTIMUS system.Results Among breast neoplasms of 123 mass studied pathologically,78 of them were benign and the rest were malignant.HBT in benign lesions(153.02±105.78)was significantly less than malignant lesions(232.95±78.22),SO_2 in benign lesions(1.0332±0.1641)was significantly elevated compared with malignant lesions(0.8794±0.1814),SDI in benign lesions(147.26±53.76)was significantly less than malignant lesions(243.98±57.27),significant differences were found between the two groups(P＜0.05).The sensitivity of differential diagnosis of breast neoplasms by the OPTIMUS system was 93.33%,the specificity was 83.33%,and the rate of accuracy was 86.99%.Conclusions OPTIMUS can improve the specificity and the rate of early diagnosis.
