Gamma imaging boasts highsensitivity for breast cancer

Breast-specific gamma imaging has the highest sensitivity for the detection of invasive lobular carcinoma, according to a study in the American Journal of Roentgenology.

Dr. Rachel Brem, from the radiology department at George Washington University in Washington, DC, and colleagues conducted a retrospective multicenter study of women with biopsyproven disease (2009;192:379-383).

Twenty-six women with 28 biopsy-proven invasive lobular carcinomas were included. All patients underwent mammography and breast-specific gamma imaging. Mammo-grams showed sensitivity of 79%, the researchers found. Gamma camera imaging showed a sensitivity of 93%.
