纳入标准:

Inclusion criteria

排除标准:

1. 钙化灶呈弥漫分布涉及多个象限,无法实现精准体表定位者; 2. 既往接受乳腺区手术或放疗导致组织严重瘢痕变形影响定位者; 3. 已知妊娠或哺乳期; 4. 存在严重系统性疾病无法耐受手术; 5. 研究者判断不适合参与者。

Exclusion criteria:

1. Diffuse microcalcifications involving multiple breast quadrants, making accurate body-surface localization infeasible; 2. Prior breast surgery or radiotherapy resulting in significant tissue scarring or breast deformity that could compromise localization accuracy; 3. Pregnancy or lactation; 4. Severe systemic comorbidities rendering the patient unsuitable for surgery; 5. Any condition deemed by the investigator to make the patient unsuitable for study participation.
