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.

Diagnostic imaging method and apparatus for the anatomical region of the pelvic floor

An apparatus for magnetic resonance imaging of patients with limbs, particularly lower limbs, under natural stress, which apparatus includes a magnet structure having an open or closed annular shape, and a predetermined axial extension, which structure delimits a cavity for receiving at least a part of the patient body, with at least two or three open sides, the open sides providing access to the cavity. The open or closed annular magnet structure being disposed with the axis of the open or closed annular shape oriented with at least one vertical directional component and devices being provided for vertical translation of the magnet structure or the patient relative to the magnet structure.
