Focused cardiac ultrasound in pregnancy
Journal of Investigative Medicine, 2023Cardiac 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 for functional neurosurgery
Journal of Neuro-Oncology, 2021Brain 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, 2021Focused 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 Ultrasound and Lithotripsy
2016Shock 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

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 ...

Treating the Brain With Focused Ultrasound
IEEE Pulse, 2023Focused ultrasound is an early stage, noninvasive therapy with the potential to treat a range of medical conditions. Like diagnostic ultrasound, it uses sound waves above the range of human hearing. But its purpose is to interact with tissues in the body, rather than just produce images of them.

Focused Ultrasound for Pediatric Diseases
Pediatrics, 2022Focused ultrasound (FUS) is a noninvasive therapeutic technology with multiple pediatric clinical applications. The ability of focused ultrasound to target tissues deep in the body without exposing children to the morbidities associated with conventional surgery, interventional procedures, or radiation offers significant advantages.

Focused ultrasound: focused on tremor
Expert Review of Medical DevicesMagnetic resonance-guided focused ultrasound (MRgFUS) has emerged as a leading noninvasive therapy for tremor, offering a precise, lesion-based alternative to deep brain stimulation (DBS) and traditional lesioning techniques. By using phased ultrasound arrays to focus energy at intracranial targets, MRgFUS allows for real-time visualization and ...

Focused Ultrasound for Chronic Pain
Neurosurgery Clinics of North America, 2022Chronic pain affects millions of Americans and is one of the leading reasons for individuals to seek medical attention. Focused ultrasound has been studied as a noninvasive treatment option for various pain disorders. Current studies have used focused ultrasound for ablation, neuromodulation, and opening of the blood-brain barrier for drug and therapy ...
