Abstract:
Objective To evaluate the feasibility and the diagnostic value of virtual touch tissues quantification(VTQ) in discriminating breast benign and malignant solid tumors.Methods A total of 72 patients with 76 breast solid tumors and the normal glandular tissues were examined by means of VTQ technique.The reproducibility of VTQ values was analyzed with intraclass correlation coefficient (ICC).Compared with the pathologic diagnosis,the cut-off point of VTQ value was determined by receiver operating characteristic curve.Results All VTQ values measured in normal glandular tissue and solid tumors of patients were with good reproducibility.The cut off point of VTQ value was determined as 6.37 m/s,sensitivity was 96.3 %,specificity was 91.8 % and accuracy was 93.4 %.Conclusions It was stable for VTQ technique appling in breast,,which is a new quantitative and helpful method in discriminating breast benign and malignant solid tumors.
