Focused ultrasound neuromodulation

2021
Focused ultrasound (FUS) is an emerging modality for performing incisionless neurosurgical procedures including thermoablation and blood-brain barrier (BBB) modulation. Emerging evidence suggests that low intensity FUS can also be used for neuromodulation with several benefits, including high spatial precision and the possibility of targeting deep ...

Focused ultrasound for functional neurosurgery

Journal of Neuro-Oncology, 2021
Brain lesioning is a fundamental technique in the functional neurosurgery world. It has been investigated for decades and presented promising results long before novel pharmacological agents were introduced to treat movement disorders, psychiatric disorders, pain, and epilepsy.

Focused Canine Cardiac Ultrasound

Veterinary Clinics of North America: Small Animal Practice, 2021
Focused cardiac ultrasound (FCU) is a useful point-of-care imaging tool to assess cardiovascular status in symptomatic dogs in the acute care setting. Unlike complete echocardiography, FCU is a time-sensitive examination involving a subset of targeted ultrasound views to identify severe cardiac abnormalities and is performed as part of an integrated ...

Focused cardiac ultrasound in pregnancy

Journal of Investigative Medicine, 2023
Cardiac disease in pregnancy is an important cause of maternal morbidity and mortality. In many high-income countries, acquired cardiac disease is now the largest cause of maternal mortality. Given its prevalence in low- and middle-income countries (LMICs), rheumatic heart disease is the most common cause of cardiac disease in pregnancy worldwide and ...

Focused Ultrasound and Lithotripsy

2016
Shock wave lithotripsy has generally been a first choice for kidney stone removal. The shock wave lithotripter uses an order of microsecond pulse durations and up to a 100 MPa pressure spike triggered at approximately 0.5-2 Hz to fragment kidney stones through mechanical mechanisms. One important mechanism is cavitation. We proposed an alternative type

MR-guided focused ultrasound

Expert Review of Medical Devices, 2007
The joining of high-intensity focused ultrasound with high-resolution MR guidance has created a system that can produce tissue destruction deep within solid organs without any invasion. Accurate targeting and thermal mapping are provided by MRI and allow very accurate deposition of energy in tissues that can be altered in response to near real-time ...
