The invention relates to a method of MR imaging of an object positioned in an examination volume of a MR device (1). It is an object of the invention to enable T2-weighted MR imaging which is essentially free from interfering contributions from MR signals without T2 weighting. The method of the invention comprises the steps of: a) subjecting the object (10) to a first T2 preparation sequence (T2PREP1) comprising an excitation RF pulse (21), one or more refocusing RF pulses (22), and a tip-up RF pulse (23); b) subjecting the object (10) to a first readout sequence (RO1) comprising at least one excitation RF pulse and switched magnetic field gradients for acquiring a first set of MR signals; c) subjecting the object (10) to a second T2 preparation sequence (T2PREP2) comprising an excitation RF pulse (21'), one or more refocusing RF pulses (22'), and a tip-up RF pulse (23'), wherein at least one of the RF pulses (21', 22', 23') of the second T2 preparation sequence (T2PREP2) has a different phase than the corresponding RF pulse (21, 22, 23) of the first T2 preparation sequence (T2PREP1); d) subjecting the object (10) to a second readout sequence (RO2) comprising at least one excitation RF pulse and switched magnetic field gradients for acquiring a second set of MR signals; e) reconstructing a MR image from the first and second sets of MR signals. Moreover, the invention relates to a MR device and to a computer program for a MR device.L'invention concerne un procédé d'imagerie par résonance magnétique (RM) d'un objet placé dans un volume d'examen d'un dispositif à RM (1). L'invention a pour objet de permettre une imagerie par RM pondérée en T2 qui est essentiellement exempte de contributions interférentes provenant de signaux de RM sans pondération en T2. Le procédé de l'invention comprend les étapes consistant : a) à soumettre l'objet (10) à une première séquence de préparation en T2 (T2PREP1) comprenant une impulsion de RF d'excitation (21), une ou plusieurs impulsion
