AbstractAbstract
[en] SAR(specific adsorption rate) regulates the quantity of the heat caused by the RF radiation to human body. This SAR is dependent on the waveform of the RF-pulse and MR Pulse Sequence. Especially SAR become high value on T1W which images the wide distance by short TE and thin slice. We succeeded in reducing the SAR value on T1W by improving the RF-pulse waveform. The reduction of the SAR value also improve the T1W contrast in the multi- slice imaging
