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.

New technique can detect small secondary brain tumours

Cancer Research UK scientists have developed a technique they believe could be used to detect tiny secondary tumours in the brain, a process that is currently impossible, according to research published in PNAS.

Obese children with PNPLA3 and GCKR genetic variants more susceptible to fatty liver disease

New research found the genetic variant Patatin-like phospholipase domain containing protein-3 (PNPLA3) acting in conjunction with the glucokinase regulatory protein (GCKR) is associated with increased susceptibility to fatty liver disease in obese children.

MRI screening could be cost effective for women with familial risk of breast cancer

Adding magnetic resonance imaging (MRI) to standard breast cancer screening approaches is expensive, though it could be cost effective for a group of women who may not have inherited the breast cancer susceptibility genes, but who have a familial risk of developing the disease.

Scans reveal Williams syndrome-associated personality/temperament traits

A personality profile marked by overly gregarious yet anxious behavior is rooted in abnormal development of a circuit hub buried deep in the front center of the brain, say scientists at the National Institutes of Health. They used three different types of brain imaging to pinpoint the suspect brain area in people with Williams syndrome, a rare genetic disorder characterized by these behaviors.

MRI perfusion imaging can help determine brain tumor progression

Gliomas, the most common malignant brain tumors in adults, can be difficult to treat because of their aggressive and invasive nature. In treating patients with gliomas, it is increasingly important that doctors be able to detect tumor changes early when there's a better chance for recovery.

MRI reveals microgravity-induced intracranial hypertension in astronauts

Magnetic resonance imaging (MRI) of the eyes and brains of 27 astronauts who have spent prolonged periods of time in space revealed optical abnormalities similar to those that can occur in intracranial hypertension of unknown cause, a potentially serious condition in which pressure builds within the skull.

Akeso Medical Imaging starts clinical study for proof of concept of imaging device for rheumatoid arthritis disease activity monitoring and control

Akeso Medical Imaging BV, announces today the start of a clinical study with their novel imaging device for assessment of joint inflammation in patient with rheumatoid arthritis (RA). In this proof of concept study, Akeso’s imaging device will be compared to other methods to assess disease status, such as the DAS-28 score, Ultrasound and in some cases MRI. The study will be performed at the University Medical Center Utrecht (UMC Utrecht) in cooperation with Regional Rheumatology Centre Eindhoven (RRC). Seventy subjects will be included; sixty RA patients with varying degrees of inflammation of the joints of hands and wrists at the time of examination and a control group of ten subjects.
