Ultrasound, a non-invasive technique commonly used to study the presence of atherosclerosis disease in blood vessels, can be used to identify patients at increased risk of future stroke who could benefit from surgery. Since surgical treatment to prevent stroke is only considered beneficial to some, ultrasound can prove useful in preventing unnecessary surgical intervention, new research shows.

Additional breast cancers found with MRI are sometimes larger and potentially more aggressive than those found on mammography, according to a new study. Researchers said that in some cases MRI findings of additional cancers not seen on mammography may necessitate a change in treatment.

A biomedical imaging system has been developed that could ultimately replace a $100,000 piece of a lab equipment with components that cost just hundreds of dollars. The system uses a technique called fluorescence lifetime imaging, which has applications in DNA sequencing and cancer diagnosis, among other things. The new work could therefore have implications for both biological research and clinical practice.

Persistent inflammation affects the brain in ways that are connected with stubborn symptoms of depression, such as anhedonia, the inability to experience pleasure. The findings bolster the case that the high-inflammation form of depression is distinct, and are guiding researchers' plans to test treatments tailored for it.

Virtual reality has potential to revolutionize some aspects of medicine and healthcare. Several medical specialties are already using it to train physicians and assist diagnosis and it also has potential for treatment. A group of cardiologists has now successfully used a VR device to guide the opening up (revascularization) of a chronically blocked right coronary artery.

A new family of nanocarriers, called '3HM,' has been developed and meets all the size and stability requirements for effectively delivering therapeutic drugs to the brain for the treatment of a deadly form of cancer known as glioblastoma multiforme.

A crucial difference in the way learning occurs in the brains of adults with autism spectrum disorder (ASD) has been identified by scientists. They have examined how the brains of typical and ASD individuals gradually became adapted to visual patterns they were learning, without awareness of the pattern, or implicit learning.

Scientists are on pace to develop the next generation of functional materials that could enable the mapping of the complex neural connections in the brain. The ultimate goal is to better understand how the billions of neurons in the brain communicate with one another during normal brain function, or dysfunction, as result of injury or disease.

Ultrasound technology will soon be helping doctors to anaesthetize patients more accurately. Ultrasound is being used in an increasing number of medical contexts, including diagnostics, treatment and examinations. Imaging techniques are also being used during narcosis in a process called 'ultrasound-guided regional anaesthesia', during which a greater part of the patient's body is anaesthetized prior to an operation. This involves a doctor injecting the anaesthetic directly around the key nerves in question.

New evidence has been found that mindfulness meditation reduces pain more effectively than placebo. The study used a two-pronged approach -- pain ratings and brain imaging -- to determine whether mindfulness meditation is merely a placebo effect. Seventy-five healthy, pain-free participants were randomly assigned to one of four groups: mindfulness meditation, placebo meditation ("sham" meditation), placebo analgesic cream (petroleum jelly) or control.

Imaging tests of obese children's hearts showed signs of heart disease, including kids as young as 8 years old. Obese children had 27 percent more muscle mass in the left ventricle of their hearts and 12 percent thicker heart muscles -- both signs of heart disease -- compared to normal weight children. Forty percent of the obese children were considered 'high-risk' because of problems with thickened muscle in the heart as well as impaired pumping ability.
