Revolutionizing brain interventions: the multifaceted potential of histotripsy

Area of Science:

• Neurosurgery
• Neurology
• Medical Imaging

Background:

• Histotripsy, a non-thermal focused ultrasound technique, is explored for diverse brain interventions.
• Current research investigates its potential beyond limited brain tumor applications.

Purpose of the Study:

• To review the broad applications and advancements of histotripsy in brain interventions.
• To highlight histotripsy's efficacy in treating conditions like tumors, hemorrhage, and neurological disorders.

Main Methods:

• Review of existing research on histotripsy in neurological and neurosurgical contexts.
• Analysis of MRI sequences (T2, T2*) for evaluating histotripsy treatment effects.
• Assessment of histotripsy's safety and efficacy in preclinical models (e.g., porcine).

Main Results:

• Histotripsy effectively reduces tumor cells with fewer pulses, minimizing bleeding and injury.
• It shows promise in creating precise brain lesions with reduced edema and inflammation.
• Histotripsy safely liquefies intracerebral hemorrhage clots without significant harm to surrounding tissue.

Conclusions:

• Histotripsy presents a versatile and promising tool for various brain interventions, including tumor treatment and hemorrhage management.
• Transcranial MR-guided histotripsy systems offer advancements over thermal ablation.
• Ongoing research aims to overcome challenges in monitoring and differentiating treatment effects for expanded clinical use.
