[MR-guided laser interstitial thermal therapy in the treatment of brain tumours and epilepsy].

ABSTRACT

MR-guided laser interstitial thermal therapy (LITT) is a minimally invasive neurosurgical procedure, which in the last decade has gained significant momentum of the treatment of intracranial tumours and epileptic foci. In brief, LITT utilises the heat from a stereotactically placed laser catheter to selectively ablate a lesion or a structure under real-time MRI guidance, which is summarised and discussed in this review. The first LITT system gained FDA approval in 2007 and was CE-marked in 2018. In December 2020, the first patient with recurrent glioblastoma was treated at the Department of Neurosurgery at Rigshospitalet, Copenhagen.
