| titleOfInvention | Method for accurately quantifying fat content through magnetic resonance imaging |
| abstract | The invention discloses a method for accurately quantifying fat content by magnetic resonance imaging, which comprises the following steps: 1) acquiring an image by adopting an MRI gradient echo sequence, and converting a multi-echo mode value image and a phase image into multi-echo complex value image data; 2) importing the multi-echo complex value image data into an IDEAL algorithm, solving the initial ratio of water and fat, and using the initial value of the water-fat ratio for the module value reconstruction; 3) taking the initial water-fat ratio as the initial value of LM (Linear model) module value fitting algorithm to obtain the water-fat ratio estimation after module value reconstruction and an image; 4) dividing multi-echo complex value image data by Attenuation coefficient of to obtain Attenuation corrected complex-valued image data: 5) importing the corrected complex value image data into an IDEAL algorithm to obtain a water-fat ratio estimation after complex value reconstruction; 6) and weighting the results obtained in 3) and 4) to obtain a final mixed weighted PDFF image. The invention can obtain the water-fat separation result with higher signal-to-noise ratio and more accurate fat quantification. |
