Objective To explore the application value of automated breast volume scanner (ABVS) and virtual-touch tissue imaging quantification (VTIQ) techniques in the diagnosis of benign and malignant breast lesions.
Methods A total of 260 breast lumps in 200 patients with breast diseases treated in Renhe Hospital, Baoshan District of Shanghai from August 2018 to July 2019 were selected. All patients were female and examined with ABVS and VTIQ. The sensitivity, specificity, and accuracy of the two methods in the differentiation of benign and malignant breast lesions were compared under single and combined application according to a gold operation or aspiration biopsy results.
Results Among the 260 masses, 68 were malignant nodules and 192 were benign nodules. The incidence of "fusion sign" on ABVS coronal view in malignant masses was significantly higher than that in benign masses (42.6% vs 2.1%, P < 0.05). The sensitivity, specificity, and accuracy were 36.83%, 91.73%, and 85.89%, respectively using "fusion sign" as the criteria for identifying benign and malignant breast masses. The mean shear wave velocity (SWV) of malignant masses was significantly higher than that of benign masses (5.92±1.53 m/s vs2.58±1.17 m/s, P < 0.01) by VTIQ test. The sensitivity, specificity, and accuracy were 94.99%, 69.82%, and 84.31%, respectively using SWV 3.65 m/s as a threshold for the identification of breast benign and malignant masses. The sensitivity, specificity, and accuracy of ABVS combined with VTIQ were 96.81%, 87.72%, and 96.78%, respectively. The area under the ROC (AUC) of ABVS combined with VTIQ in the differential diagnosis of breast benign and malignant masses was 0.983, which was higher than that of ABVS (0.852) and VTIQ (0.924).
Conclusions Both ABVS and VTIQ techniques have high value in differentiating breast benign and malignant masses. Moreover, the combined use of the two methods is more accurate in the diagnosis, which can be widely used in clinical practice.
