Abstract:

Objective To investigate the influence of ultrasound imaging parameters on the diagnosis of S?Detect technology. Methods Between October 2021 and March 2022, a total of 143 breast nodules from 133 patients were included in this study. Five ultrasound imaging parameters were set, including basic parameter (single focus, focus located at the middle level of the lesion, and suitable depth of the lesion), dual focus parameter, superficial focus location, over?depth focus location, and scanning over?depth parameter. The ultrasound images were preserved in different ultrasound imaging parameters to obtain the results of S?Detect. The consistency of diagnosis and ultrasonographic feature interpretation under different ultrasound imaging parameters were investigated. And the diagnostic performance under the four parameters were compared with the basic one. The pathologic results were used as a “golden standard”. Results The diagnostic consistency (kappa = 0.771) of the scanning over?depth parameter was lower than the other settings. The consistency of interpretation of the two ultrasonographic features [shape (kappa = 0.489) and internal echo (kappa = 0.442)] were also lower than the other settings. Meanwhile, the diagnostic performance of the scanning over?depth parameter (AUC = 0.716) was the lowest among those ultrasound imaging parameters, and it has the largest gap with the diagnostic efficacy of the basic parameter setting. The other parameter conditions was consistent with the basic parameter, and there was no significant difference between the diagnostic efficacy and basic parameter setting. Conclusions As compared with the basic imaging parameter setting, the consistency of diagnosis, the ultrasonographic feature interpretation and diagnostic performance of the scanning over?depth setting were lower than other ultrasound imaging settings. Therefore, the scanning over?depth settings should be avoided when applying the S?Detect technology.
