To evaluate the diagnostic performance of a new two-dimensional shear wave speed (SWS) imaging (i.e. Toshiba shear wave elastography, T-SWE) in differential diagnosis of breast lesions. 225 pathologically confirmed breast lesions in 218 patients were subject to conventional ultrasound and T-SWE examinations. The mean, standard deviation and ratio of SWS values (m/s) and elastic modulus (KPa) on T-SWE were computed. Besides, the 2D elastic images were classified into four color patterns. The area under the receiver operating characteristic (AUROC) curve analysis was performed to evaluate the diagnostic performance of T-SWE in differentiation of breast lesions. Compared with other quantitative T-SWE parameters, mean value expressed in KPa had the highest AUROC value (AUROC = 0.943), with corresponding cut-off value of 36.1 KPa, sensitivity of 85.1%, specificity of 96.6%, accuracy of 94.2%, PPV of 87.0%, and NPV of 96.1%. The AUROC of qualitative color patterns in this study obtained the best performance (AUROC = 0.957), while the differences were not significant except for that of Eratio expressed in m/s (AUROC = 0.863) (P = 0.03). In summary, qualitative color patterns of T-SWE obtained the best performance in all parameters, while mean stiffness (36.05 KPa) provided the best diagnostic performance in the quantitative parameters.

“…This pattern corresponds to an Italian elastosonographic score of 3 or 4 [6]. This appearance may depend on the amount of fibrous tissue present in hamartomas; in fact, the different tissues that make up the breast have distinct elastographic features, with fibrous and glandular tissues displaying greater stiffness than fat tissue [7,8] (Figs. 4, 5, 6).…”

Hamartomas, also known as fibroadenolipomas, are rare, benign formations that can develop in various organs, including the breast. They present clinically as a soft, mobile nodular lesions and are generally asymptomatic. They may be discovered incidentally during imaging studies performed for other reasons. Owing to the increasingly widespread use of mammographic screening, the diagnosis of breast hamartomas is on the rise. The masses are associated with specific mammographic and sonographic features that reflect their diverse tissue components. They also appear to present reproducible features on elastography. This article reviews the typical features of breast hamartomas seen on these three imaging modalities.Keywords Breast hamartoma Á Ultrasound Á Breast elastography Sommario L'amartoma, o fibroadenolipoma, è una rara formazione benigna che può insorgere in diversi organi, tra i quali la mammella. Clinicamente si presenta con aspetto nodulare soffice e mobile rispetto ai piani circostanti; generalmente asintomatico, può rappresentare un riscontro occasionale nel corso di esami strumentali, in particolare la diffusione dei programmi di screening mammografico ha comportato un maggiore riscontro di tale lesione. Presenta caratteristiche mammografiche ed ecografiche peculiari, legate alle differenti componenti tissutali che lo costituiscono. Anche l'elastonosografia mostra aspetti riproducibili.Vengono presentati gli aspetti tipici di questa lesione con ecografia, mammografia ed elastosonografia.

Elastography ultrasound for breast lesions: fat-to-lesion strain ratio vs gland-to-lesion strain ratio

Abstract: FLR was higher than GLR in both malignant and benign breast lesions. Both FLR and GLR were higher in malignant than in benign breast lesions. FLR yielded better diagnostic performance than GLR in breast lesions.
