In a method for improving the contrast of magnetization-transfer-prepared magnetic resonance imaging (MRI), an acquisition scheme comprising a plurality of inversion-recovery (IR)-imaging modules in an interleaved arrangement is selected, a number of magnetization-transfer (MT)-preparation modules is selected, a pulse sequence is generated by arranging at least one MT-preparation module of the number of MT-preparation modules between two successive IR-preparation modules of the interleaved IR-imaging modules or in front of the first IR-preparation module of a group of interleaved IR-imaging modules, and the pulse sequence for an MRI examination is applied or saved. Each IR-imaging module may include an IR-preparation module and a slice acquisition module.

The disclosure relates to techniques for an improved recording of scan data, which can be recorded from at least two slices of an examination object simultaneously by means of a magnetic resonance system. The technique includes selecting a desired simultaneous recording of scan data from at least two slices (S1, Sn), determining an artifact-preventing minimum RF pulse duration (dRF) for a desired recording, considering desired recording parameters (PA), and performing the desired recording using the determined minimum RF pulse duration.

The present disclosure relates to systems and methods for magnetic resonance imaging. The method may include obtaining primary imaging data associated with a region of interest (ROI) of a subject and obtaining secondary data associated with the ROI. The method may also include determining secondary imaging data based on the secondary data by using a trained model. The method may further include reconstructing a magnetic resonance image based on the primary imaging data and the secondary imaging data.

An angle adjuster for nuclear magnetic resonance (NMR) includes a linear motion member composed of a shaft and a support member, a rotary member, a conversion mechanism, and a spring. The linear motion member is a member that serves to change, in an NMR probe device, an angle of a sample tube by a linear motion. The rotary member is rotated by a motor. The conversion mechanism converts a rotary motion of the rotary member into a linear motion of the linear motion member. The spring provides, at a portion where the linear motion member and the rotary member are in engagement with each other, a force that urges the linear motion member in one direction toward the rotary member.

An excitation region setting method according to an embodiment includes: receiving a designation of a first region from a user, the first region being designated in a distortion-corrected image that is a magnetic resonance image in which an effect of a distortion of a magnetic field has been corrected; calculating an actual excitation region where a subject is to be excited, based on the designated first region and the effect of the distortion of the magnetic field; and correcting imaging conditions including at least one of an orientation of a slice plane that defines the actual excitation region, or a frequency of a high-frequency magnetic field applied to the subject, in such a manner that the calculated actual excitation region becomes closer to an ideal excitation region represented as the first region.

A magnetic resonance imaging apparatus comprises a scanning unit for performing a pulse sequence PS including a MT (Magnetization Transfer) pulse b for lessening signals from the cerebral parenchyma (white matter and gray matter). The scanning unit performs the pulse sequence PS in periods of time P1 and P3 in the pulse sequence PS so that the MT pulse b is applied every repetition time TR, while it performs the pulse sequence PS in a period of time P2 in the pulse sequence PS so that no MT pulse b is applied.

The subject matter disclosed herein relates to a method for determining dopamine function in a subject, the method comprising acquiring one or more neuromelanin-Magnetic Resonance Imaging (NM-MRI) scans of the subject's dopamine-associated brain region of interest.

A method includes displaying a position of a distal end of a medical probe that is being navigated in an organ of a patient on a three-dimensional (3D) map of the organ. In response to an event, a plane of interest including the distal end is selected, a real-time Magnetic Resonance Imaging (MRI) slice of the organ is acquired at the selected plane, and the MRI slice is displayed overlaid on the 3D map.
