摘要
A method for producing an image of a subject with a magnetic resonance imaging (MRI) system is provided. Image data is acquired at a sequence of multiple echo times occurring within two or more repetition times (TRs). Odd-numbered echoes are sampled during odd-numbered TRs, and even-numbered echoes are sampled during even-numbered TRs. Images are reconstructed and used to calculate the respective signal contributions of two or more chemical species using, for example, an IDEAL separation technique. The respective signal contributions are then used to produce images that depicts substantially only one of the chemical species. For example, separated water and fat images may be produced.
