Benign versus malignant breast disease: comparison of contrast-enhanced MR imaging and Tc-99m tetrofosmin scintimammography.

Although both techniques accurately differentiate benign from malignant palpable breast masses, scintimammography is more accurate in the posttreatment breast. Because of lower cost, wider availability, and high patient acceptance, scintimammography may provide a valuable alternative to MR imaging for noninvasive characterization of palpable breast disease.
