“…Therefore, in the clinical observation of superficial tissue, gel pads are often used to increase the near-field distance and improve the permeability of media to achieve ultrasonic resolution in superficial tissue. Studies have shown that gel pads are superior to ordinary liquid coupling gels through the transmission of high-frequency sound energy, and with coupling gels, tiny bubbles are contained in liquid couplings, possibly causing ultrasonic artefacts and affecting the visibility of superficial skin structures [ 12 , 13 ]. Furthermore, some masses in superficial tissues are raised to the skin surface, irregularly shaped or located in uneven skin sites, which creates contact difficulty between the ultrasound probe and tissue, limiting the image display range.…”

Objective This study aimed to compare the repeatability and diagnostic efficiency of shear wave elastography (SWE) while using coupling gel and gel pads in the diagnosis of superficial breast lesions. Methods Two experienced sonographers, trained in SWE, used different methods to perform the maximum Young’s modulus (Emax) measurement of the lesion while using coupling gel SWE and gel pad SWE at different time points. All 80 lesions were in the superficial layer of the breast. The interclass correlation coefficient (ICC) was calculated to evaluate the intraobserver and interobserver repeatability. Meanwhile, the receiver operating characteristic curve (ROC curve) was used to calculate the sensitivity, specificity and area under the curve of the two methods. Results In the 80 breast lesions, the intraobserver and interobserver reproducibility of SWE measurements using coupling gel were considered good, and the ICCs were 0.728 (95% CI: 0.509–0.813) and 0.702 (95% CI: 0.492–0.795), respectively. The intraobserver and interobserver reproducibility of the SWE measured by the gel pad were also considered good, and the ICCs were 0.745 (95% CI: 0.501–0.801) and 0.713 (95% CI: 0.498–0.802), respectively. The sensitivity, specificity and area under the curve were 0.711 and 0.737, 0.929 and 0.905, and 0.873 and 0.878, respectively. Conclusions In the SWE measurement of superficial breast lesions, the use of a gel pad does not affect the repeatability and diagnostic efficiency of the measurement.
