Device Enables Non-Invasive and Safe Ultrasound Brain Treatments
Current approaches in ultrasound-based therapies for the brain are focusing ultrasound waves to reach their specific target in the brain. But this has proven difficult, as ultrasound tends to bounce around within the skull, which leads to some areas of the brain being over-exposed while others are not exposed enough. Now, a team of engineers has developed a device that is a first step to enabling noninvasive, ultrasound-based therapies for the brain. More...29 Mar 2022
Focused Ultrasound Bursts Offer Alternative for Noninvasive Treatment of Kidney Stones
Small kidney stones can be treated using a technique called extracorporeal shock wave lithotripsy (ESWL), using shock waves to break up the stones so that they will be more likely to pass on their own. However, an innovative technique called burst wave lithotripsy (BWL) may provide an effective, more accessible alternative for noninvasive treatment of kidney stones, according to initial human studies.

Novel Heart Ultrasound Measures Can Predict Risk of Developing Dementia
In a study to assess if there is a link between heart health and dementia, researchers have been able to identify novel measures that are linked to a higher dementia risk by using echocardiography - visual ultrasound of the heart. More...25 Mar 2022
New Quantitative Imaging Markers Could Improve Cancer Detection, Diagnosis and Treatment
Medical imaging is an essential tool to help doctors and scientists assess the size and scope of a tumor that will be effectively removed by surgery, as well as the rate at which tumors shrink in response to medical interventions such as chemotherapy or radiation therapy. Researchers are now investigating multiple avenues, including the development of quantitative imaging markers, to help improve medical imaging use in cancer detection, diagnosis and treatment.

Ultrasound Can Effectively Predict Ovarian Cancer and Prevent Unnecessary Surgery
In a new study, researchers at the University of Rochester Medical Center (Rochester, NY, USA) assessed a method that uses ultrasound images to classify adnexal lesions into one of two categories: classic or non-classic. The study's findings confirm that the appearance of ovarian lesions on ultrasound is an effective predictor of cancer risk that can help women avoid unnecessary surgery. More...24 Mar 2022
Brain Mapping Study Using Large-Scale MRI Images Aims to Detect Alzheimer’s Disease Earlier
About 50 million people worldwide are living with Alzheimer’s and forms of dementia, according to the Alzheimer’s Association. The disease kills more people than breast and prostate cancers combined. Now, a new study will map the brain using large-scale magnetic resonance (MRI) images in an effort to identify stable brain landmarks called ‘anchor-nodes’ and detect Alzheimer’s disease earlier. More...23 Mar 2022
