摘要： A magnet structure for an MRI apparatus utilizing a permanent magnet, which apparatus has an inverted U shape with two essentially parallel opposed pole pieces, which are supported at a predetermined distance from each other by an inverted U-shaped magnetic yoke, which pole pieces and/or at least a portion of which yoke delimit a cavity for receiving at least a part of the patient's body, whereas a partial volume is generated in the volume of said cavity, which has such magnetic field values as to provide MRI images of a sufficient quality to enable the use thereof as diagnostic images, i.e. a so-called imaging volume. According to the invention, the distance (D1) between the pole pieces (1, 2) of the magnet structure is of 36 to 42 cm, and the pole pieces (1, 2) have a surface area of 4500 to 5500 cm2. The invention also relates to an MRI imaging apparatus, particularly designed for the spine region, or a part thereof, and which has a magnet structure as described above.

摘要： A method for determining information for a diagnosis of pathologic conditions of the anatomical region of the pelvic floor by MRI imaging includes acquiring a sequence of MRI images along one or more predetermined section planes or inside a predetermined three-dimensional area, which planes intersect or which three-dimensional area contains at least a part of the pelvic floor. The image sequence is acquired for a time interval coinciding with or including at least a part of the length of the physiological process evacuating natural solids or liquids carried out on the basis both of a natural stimulation and an induced stimulation or during a simulation of physiological processes evacuating solids or liquids by introducing foreign bodies or substances simulating natural products. The method further includes generating a film of the cinematographic type by using as individual frames one or more images of the sequence and displaying the film for visually verifying the dynamic-morphologic behavior of organs of the pelvic floor.

摘要： Method for displaying MRI images including the following steps: displaying a plurality of different images one after the other obtained by nuclear magnetic resonance image acquisition, each of which images is different with respect to at least a part of the other images due to the fact that the plane of the displayed image corresponds to a different section plane through a body or part thereof under examination having a predetermined different position and/or a predetermined different orientation with respect to the body under examination and to a reference system; and the passage from displaying an image to display a further image is achieved by control means which define the position and/or orientation of different section planes of different images.
