PROBLEM TO BE SOLVED: To prevent a reference section containing both a needling start position and a target from being shifted due to breathing and body motions of an object. SOLUTION: A magnetic resonance imaging system used for interventional MRI involving operations of a device to be inserted into an object and for obtaining an image of a section from an MR signal acquired through application of magnetic fields on a predetermined pulse sequence on the object, the magnetic resonance imaging system includes positional detection means and control means. The positional detection means detects positional information of the device. The control means controls imaging parameters included in the pulse sequence on the basis of the positional information of the device so that the section always contains the device.
