Comparison of MR Imaging Breast Coils¹

¹ From the Department of Imaging Research, Sunnybrook and Women’s College Health Sciences Centre, 2075 Bayview Ave, Toronto, Ontario, Canada M4N 3M5 (N.B.K., E.A.R., M.J.B., D.B.P.); and Department of Medical Biophysics, University of Toronto, Ontario, Canada (M.J.B., D.B.P.). Received July 25, 2000; revision requested August 21; final revision received September 5, 2001; accepted September 4.

In one volunteer, five breast coils were evaluated for signal-to-noise ratio (SNR), uniformity, comfort, subject orientation, access to the breast, and unilateral imaging options. The four-coil arrays provided superior SNR, imaging flexibility, and access. Uniformity and comfort were issues with all coils. Substantial design differences exist between coils; purchasers should ensure that their specific requirements are met.
