Magnetic resonance imaging (MRI) is an imaging technique which physicians use for the diagnosis and treatment of medical conditions.

Automated magnetic resonance imaging technique assists in earlier Alzheimer's diagnosis

An automated system for measuring brain tissue with magnetic resonance imaging (MRI) can help physicians more accurately diagnose Alzheimer's disease at an earlier stage according to a new study published in the July issue of the journal Radiology.

Noninvasive molecular imaging technology helps track stem cells in tumors

Using noninvasive molecular imaging technology, a method has been developed to track the location and activity of mesenchymal stem cells (MSCs) in the tumors of living organisms, according to researchers at the Society of Nuclear Medicine's 55th Annual Meeting. This ability could lead to major advances in the use of stem cell therapies to treat cancer.

Unique brain maps to assist surgery and research

Researchers from the Howard Florey Institute in Melbourne are developing new technology to create individualised brain maps that will revolutionise diagnosis of disease and enhance the accuracy of brain surgery.

Transfer of learning traced to areas of the brain

Practice makes perfect, but a question that still remains a mystery is why it is so difficult to transfer learning from a trained to an untrained task? Why are we no better at remembering faces when we have been training our memory for words? Scientists at Umea University and Karolinska Institutet in Sweden now show in the journal Science that the answer lies in the brain areas activated by each task.

Cancer-detecting nanoparticles

Magnetic resonance imaging (MRI) can be a doctor's best friend for detecting a tumor in the body without resorting to surgery. MRI scans use pulses of magnetic waves and gauge the return signals to identify different types of tissue in the body, distinguishing bone from muscle, fluids from solids, and so on.

Did you ever wonder why it is so difficult to part with your stuff?

A new study reveals fascinating insights into the specific neuropsychological mechanisms that are linked with the potential loss of possessions.

Memory loss linked to sleep apnea

For the first time, UCLA researchers have discovered that people with sleep apnea show tissue loss in brain regions that help store memory.

Long term dope use shrinks the brain

According to Australian researchers the long term use of marijuana may cause parts of the brain which control memory, emotion and aggression, to shrink.

Meniscal damage and joint malalignment predictors of cartilage loss

Marked by cartilage and bone degradation, progressive knee osteoarthritis (OA) is believed to result in part from a combination of several local mechanical factors. Lack of joint stability, poor joint alignment and injuries to the disks of meniscal tissue that cushion the knee all affect load distribution and the toll to the vulnerable OA knee.

Long-term, heavy cannabis use may shrink brain's hippocampus and amygdala

Long-term, heavy cannabis use may be associated with structural abnormalities in areas of the brain known as the hippocampus and amygdala, according to a report in the June issue of Archives of General Psychiatry.

Young age may provide survival advantage to children with certain brain tumors

St. Jude Children's Research Hospital investigators have shown that children under 3 years old who have a brain tumor called diffuse pontine glioma (DPG) appear to have a better outcome than older children with the same cancer.

Body's baking soda used to catch cancer early

A chemical commonly called baking soda which is found naturally in the body could be used to detect cancer with magnetic resonance imaging, reveals a Cancer Research UK study published in Nature.

New insights into the neural circuitry of trust

The brain centers triggered by a betrayal of trust have been identified by researchers, who found they could suppress such triggering and maintain trust by administering the brain chemical oxytocin. The researchers said their findings not only offer basic insights into the neural machinery underlying trust; the results may also help in understanding the neural basis of social disorders such as phobias and autism.

Sleep deprived brain not to be trusted

Scientists are warning that sleep derivation affects how well the brain performs - they say any reliance on a sleep deprived-brain to perform well is potentially dangerous

Nanoworms target tumors

By linking strings of spherical iron oxide nanoparticles and coating the resulting construct with a biocompatible polymer, a multi-institutional research team has created "nanoworms" that can better target tumors and produce stronger magnetic resonance imaging (MRI) signals than their component nanoparticles. The nanoworms also appear to be a promising vehicle for carrying anticancer drugs into tumors. The researchers published their work in the journal Advanced Materials.
