[Intraoperative magnetic resonance imaging. Fifteen years' experience in the neurosurgical hybrid operating suite].

Intraoperative magnetic resonance imaging was established 15 years ago due to special requirements for the resection of cerebral gliomas. Several studies have independently shown an increase of the extent of resection of the tumor and also an improved survival of the patients. Technical innovations combined with an easier operation of this imaging modality led to widespread implementation of this method. The introduction of functional and metabolic imaging opened up new prospects of further improving the therapeutic outcome.
