[Ultra-low field magnetic resonance in the diagnosis of ovarian lesions].

To investigate the diagnostic capabilities of ultra low field MRI in the characterization of adnexal conditions, 46 women (aged 17 to 83 years) with US diagnosis of tubo-ovarian diseases were examined with MRI. An 0.064 T permanent magnet was used (toshiba Access), with T1- and T2-weighted spin-echo (SE) sequences, 3D T1-weighted gradient-echo (GE) sequences and, in 5 patients, a STIR sequence.
