<B>B1+</B> and <B>E</B> field inside a birdcage coil with and without a high-dielectric tube insert were investigated by finite difference time domain method. The high-dielectric insert can help to increase <B>B1+</B> field and decrease <B>E</B> field, which means high-dielectric insert has potential to increase signal to noise ratio.
