Magnetic Resonance Imaging (MRI) News and Research

RSS

Magnetic resonance imaging (MRI) uses a large magnet and radio waves to look at organs and structures inside your body. Health care professionals use MRI scans to diagnose a variety of conditions, from torn ligaments to tumors. MRIs are very useful for examining the brain and spinal cord. Also called: Magnetic resonance imaging, NMR, Nuclear magnetic resonance.

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.

Fireflies' glow helps researchers track cancer drug's effectiveness

The gene that allows fireflies to flash is helping researchers track the effectiveness of anti-cancer drugs over time.

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.

New clinical research and imaging centre for Bristol

The University and United Bristol Healthcare Trust (UBHT) are joining forces to establish a new state-of-the-art Clinical Research and Imaging Centre (CRIC) at St Michael's Hospital on St Michael's Hill

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.

Dendrimers improve imaging with magnetic nanoparticles

Dendrimers are spherical polymer nanoparticles that have shown promise as targeted anticancer drug delivery vehicles. Iron oxide nanoparticles have already demonstrated the ability to image tumors and metastatic lesions.

Drug therapy for phenylketonuria reverses heart damage

A pricy drug used to treat a rare but well-known genetic disorder may hold wider promise as a treatment for millions of Americans with potentially lethal enlarged hearts, due mainly to high blood pressure, a study from Johns Hopkins shows.

Supplemental breast ultrasound boosts cancer detection, radiologist reports in national study

Among women at high-risk of developing breast cancer, breast ultrasound combined with mammography may detect more cancers than mammography alone, according to results of a multicenter trial that included UT Southwestern Medical Center researchers.

New MRI technique detects subtle but serious brain injury

A new technique for analyzing magnetic resonance imaging data, developed by researchers at UT Southwestern Medical Center, can reveal serious brain injury missed by current tests and help predict a patient's degree of recovery.

Nanoworms developed to target tumors

Scientists at UC San Diego, UC Santa Barbara and MIT have developed nanometer-sized "nanoworms" that can cruise through the bloodstream without significant interference from the body's immune defense system and-like tiny anti-cancer missiles-home in on tumors.

Gut hormone makes food appear more desirable

A gut hormone that causes people to eat more does so by making food appear more desirable, suggests a new report in the May issue of Cell Metabolism, a publication of Cell Press. In a brain imaging study of individuals, the researchers found that reward centers respond more strongly to pictures of food in subjects who had received an infusion of the hormone known as ghrelin.

Alcohol affects threat-detecting brain circuits

New brain imaging research published this week shows that, after consuming alcohol, social drinkers had decreased sensitivity in brain regions involved in detecting threats, and increased activity in brain regions involved in reward.

Effectiveness of decompression surgery in patients with cervical spinal cord injuries

Every year, nearly 12,000 individuals in the United States and Canada, mostly young adults, sustain a spinal cord injury (SCI). According to the Centers for Diseases Control and Prevention (CDC), SCI costs an estimated $9.7 billion each year in the United States alone.
