METHOD FOR PREVENTING PARTIAL SATURATION OF IMAGE PORTION BY USING PRESATURATION OF DUAL BANDWIDTH

摘要

PURPOSE: Provided is a method for preventing partial saturation of image portion by using presaturation of TOF(Time of Flight) which is one method of magnetic resonance imaging for getting image of blood vessel, therefore regardless of blood flow rate, unexpected blood vessel signal is contained to image portion partially. CONSTITUTION: A method for preventing partial saturation of image portion comprises the steps of: preventing inflow of unexpected blood vessel signal as well as partial saturation of imaging slice by obtaining dual presaturation bandwidth having different bandwidth so as not to overlap with imaging slice when sending RF(radio frequency) from RF coil to object and receiving from the object; and displaying expected image according to the presaturation result.
