Breast-specific gamma imaging of invasive breast cancer: Clinicopathologic factors affecting detectability and correlation with mammographic findings

Purpose: To investigate the factors affecting detectability of invasive breast cancers on BSGI. Material and methods: We evaluated BSGI, mammography and pathologic reports of 89 patients with invasive breast cancers. Results: 87.6% were visible on BSGI. Cancer in old or postmenopausal women were more visible on BSGI (p = 0.003, 0.046). Cancers >= 1.0 cm in size were significantly more visible on BSGI than those < 1 cm in size (p = 0.002). Cancers in fatty breasts were more visible than those in dense breasts (p = 0.042). Conclusion: Invasive cancers in older, postmenopausal patients, cancers with size >= 1.0 cm, and those with fatty breast are better visualized by BSGI, than those in younger, premenopausal patients, with size < 1.0 cm and dense breast.
