MRI of chemical species having different resonance frequencies using an ultra-short echo time sequence

摘要

The invention relates to a method of MR imaging of chemical species having at least two different MR resonance frequencies, the method comprising the steps of:- generating MR signals at that at least two different resonance frequencies of the chemical species by subjecting a portion of a body (10) to an imaging sequence of RF pulses and switched magnetic field gradients, which imaging sequence is an ultra-short echo time sequence;- acquiring the MR signals;- reconstructing a MR image from the acquired MR signals. Moreover, the invention relates to a MR device and to a computer program to be run on a MR device.
