Abstract: In a methods and devices for magnetic resonance (MR) imaging, an MR data acquisition is implemented repeatedly in which an examination subject is exposed to an alternating magnetic field with a frequency before the readout sequence. The signal values acquired after the preparation of the magnetization with alternating fields of respectively different frequencies are evaluated. Magnetic field data that contain information about the curve of the basic field are used to implement the MR data acquisitions, such as to establish the frequencies, and/or in the evaluation of the signal values.

Abstract: In a magnetic resonance method and system to correct spatial shifts in MR data, at least two measurement data sets are acquired, the additional measurement data set or sets being acquired while switching an additional gradient relative to acquisition of the first measurement data set. For respective corresponding measurement points of the measurement data sets, a phase difference is initially determined from the first measurement data set and at least one additional measurement data set acquired with the additional gradient, with a spatial shift of the measurement points of the first measurement data set being determined from the spatial shift. The magnitude values of the initially measured measurement points are distributed to their correct spatial position corresponding to the determined spatial shifts, so a corrected image data set is created.

Abstract: In order to increase the signal to noise ratio, and thus increase the quality of images produced during pediatric MRI, a pediatric RF coil assembly includes a head coil and a flexible body coil in a single dedicated device shaped and sized for a child. The flexible body coil may be operable to at least partially surround and abut the body of the child located on the pediatric RF coil assembly, while the head coil may at least partially surround and abut the head of the child located on the pediatric RF coil assembly. In order to optimize workflow, the child may be positioned on the pediatric RF coil assembly in a first room and moved to a second room including an MRI system after the child is brought to sleep or sedated in the first room. The pediatric RF coil assembly and the child may be moved to the second room using a handle rotatably attached to the pediatric RF coil assembly, and may be positioned on a patient table of the MRI system when the imaging process is to begin.
