Title:
T2/T2*の重み付けを低減した中位の磁場強度における水分および脂肪のMR画像の区別および識別
Document Type and Number:
Japanese Patent JP4166527
Kind Code:
B2
Abstract:
A magnetic resonance imaging (MRI) method is disclosed for generating and identifying water and fat separated MR images. Image data is first acquired to obtain two echo images with the water and fat signals orthogonal in the first echo image, and parallel/anti-parallel in the second echo image. The effect of background field inhomogeneties are removed, and water and fat images are separated from each other. The separated water and fat images are identified according to the difference of their precessing frequencies.
