Enhanced proton magnetic resonance imaging of experimental mammary tumors

The proton magnetic resonance imaging contrast of experimental mammary tumors in rats has been dramatically improved. The technique developed combines T 2 weighting and chemical‐shift imaging in order to suppress the thoracic wall, muscle, and subcutaneous fat contributions to the image. The technique is demonstrated using the R3230AC mammary adenocarcinoma in F344 rats at 4.7 T. © 1988 Academic Press, Inc.
