Chirurgia trans-cranica mediante ultrasuoni focalizzati ad alta intensità su guida RM: esperienza preliminare a 1,5T
2015
Da qualche anno la chirurgia mediante ultrasuoni focalizzati ad alta intensità guidati da Risonanza Magnetica (Magnetic Resonance guided Focused Ultrasound Surgery, MRgFUS) si sta diffondendo anche in Italia per la palliazione del dolore da metastasi ossee, per il trattamento di tumori ossei primitivi (benigni e non), dei fibromi e dell’adenomiosi uterina; sono già stati inoltre pubblicati i risultati preliminari del trattamento di alcuni tumori epatici, pancreatici, prostatici e della mammella mediante MRgFUS. Questa innovativa tecnica prevede l’utilizzo di un’apparecchiatura di Risonanza Magnetica per il monitoraggio della procedura e sfrutta le caratteristiche fisico- meccaniche degli …
Transcranial magnetic resonance-guided focused ultrasound surgery at 1.5T: a technical note.
2019
Magnetic resonance-guided focused ultrasound is one of the emerging non-invasive technologies offering both image guidance and thermal monitoring. In recent years transcranial application of this technology is starting to impact heavily the neuroscience field. We present here the imaging protocol and the technological methods successfully used with a transcranial magnetic resonance-guided focused ultrasound system certified for clinical treatments of functional neurological disorders, integrated for the first time with a 1.5T magnetic resonance scanner. Compared to the body radiofrequency coil (the one commonly used with transcranial magnetic resonance-guided focused ultrasound system integ…

OBJECTIVETranscranial magnetic resonance–guided focused ultrasound surgery (tcMRgFUS) is one of the emerging noninvasive technologies for the treatment of neurological disorders such as essential tremor (ET), idiopathic asymmetrical tremor-dominant Parkinson’s disease (PD), and neuropathic pain. In this clinical series the authors present the preliminary results achieved with the world’s first tcMRgFUS system integrated with a 1.5-T MRI unit.METHODSThe authors describe the results of tcMRgFUS in a sample of patients with ET and with PD who underwent the procedure during the period from January 2015 to September 2017. A monolateral ventralis intermedius nucleus (VIM) thalamic ablation was pe…
