ABSTRACT
BACKGROUND:
Both MRI and breast-specific gamma imaging are tools for surgical planning in newly diagnosed breast cancer. Breast-specific gamma imaging (BSGI) is used less frequently although it is of similar utility and lower cost. We compared the diagnostic and cost efficacy of BSGI with MRI.METHODS:
Retrospective review of 1,480 BSGIs was performed in a community breast health center, 539 had a new diagnosis of cancer, 75 patients having both MRI and BSGI performed within 2 months of each other. Institutional charges for BSGI ($850) and MRI ($3,381) were noted.RESULTS:
BSGI had a sensitivity of 92%, specificity of 73%, positive predictive value of 78%, and negative predictive value of 90%. This compared favorably with MRI that had sensitivity of 89%, specificity 54%, positive predictive value 67%, and negative predictive value 83%. The accuracy of BSGI was higher at 82% vs MRI at 72%. Total cost of MRI imaging was $253,575 vs BSGI at $63,750.CONCLUSIONS:
BSGI is a cost-effective and accurate imaging study for further evaluation of dense breast tissue and new diagnosis of cancer.Palabras clave
