| titleOfInvention | Chemical exchange saturation transfer imaging method for eliminating fat artifact |
| abstract | The invention discloses a chemical exchange saturation transfer imaging method for eliminating fat artifacts, which comprises the steps of image acquisition and image reconstruction, wherein the image acquisition is to acquire a mode image and a phase image of magnetic resonance imaging by adopting a multi-echo gradient echo sequence under the condition of no saturated radio frequency irradiation and under the condition of irradiation of saturated radio frequencies with different frequencies; the image reconstruction: reconstructing a water map, a fat map, a field map and a data set acquired under illumination of unsaturated radio frequencies based on a multimodal fat model A drawing; updating the fat model in the data acquired after the saturated radio frequency irradiation with different frequencies by using a numerical method; reconstructing a water map and a fat map based on the updated fat model for data acquired under the saturated radio frequency irradiation of different frequencies; the accurate water-fat reconstruction of the invention ensures that no fat signal interference exists in the water map, effectively eliminates fat artifacts appearing in the chemical exchange saturation transfer imaging, and can improve the accuracy of the chemical exchange saturation transfer imaging. |
