Abstract

The proton magnetic resonance imaging contrast of experimental mammary tumors in rats has been dramatically improved. The technique developed combines T2 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.

摘要

大鼠实验性乳腺肿瘤的质子磁共振成像对比度得到了显著改善。所开发的技术结合了T2加权和化学位移成像，以抑制胸壁、肌肉和皮下脂肪对图像的贡献。该技术在4.7T场强下，以F344大鼠的R3230AC乳腺腺癌为例进行了演示。
