摘要： A method for magnetic resonance imaging, in which a magnetic resonance imaging device employs a multi-echo imaging sequence, includes the steps of: applying, to one of the multiple echoes, a first number of steps of phase encoding, applying a readout gradient, and collecting the data of this echo to reconstruct an anatomical image; and applying, to another one of the multiple echoes, a second number of steps of phase encoding, applying a readout gradient, and collecting the data of this echo to construct a temperature image. The method is capable of obtaining at the same time both a temperature image with high time resolution and an anatomical image with high spatial resolution.

摘要： A method for generating a spatially resolved magnetic resonance dataset using a coil arrangement includes providing at least one correction datum based on receiver characteristics of the coil arrangement. The method also includes providing a magnetic resonance dataset with spatially resolved signal intensity data, and correcting the at least one signal intensity datum in the magnetic resonance dataset by the correction datum before or after providing the magnetic resonance dataset.
