Earlier this year, researchers at the University of Washington reported that they had developed a toxin-nanoparticle combination that inhibits brain cancer invasion when added to tumor cells growing in culture. [More]

A new review says using magnetic resonance imaging (MRI) before surgery to assess the extent of early breast cancer has not been shown to improve surgical planning, reduce follow-up surgery, or reduce the risk of local recurrences. [More]

In the political minefield of healthcare reform, medical imaging has emerged as a microcosm of this contentious debate. Congress has been charged with a high stakes, high wire balancing act: to create a bill preserving quality and access while trimming unethical and unnecessary spending. Medical imaging represents such a challenge, with its undeniable benefits tainted by inappropriate use. [More]

Brain cancer is among the deadliest of cancers. It's also one of the hardest to treat. Imaging results are often imprecise because brain cancers are extremely invasive. Surgeons must saw through the skull and safely remove as much of the tumor as they can. Then doctors use radiation or chemotherapy to destroy cancerous cells in the surrounding tissue. [More]

A combination of biochemical and MRI markers will allow improved measurement of osteoarthritis (OA) progression. The biomarkers, described in BioMed Central's open access journal Arthritis Research and Therapy, will be useful for the design and interpretation of trials of new disease modifying drugs. [More]

A new technology involving the fusion of four different types of images into a 3-D map of a patient's brain has helped University of Cincinnati (UC) specialists successfully remove a fist-sized tumor from the brain of an Indiana woman. [More]

Changes in the brain measured with MRI and PET scans, combined with memory tests and detection of risk proteins in body fluids, may lead to earlier and more accurate diagnosis of Alzheimer's, according to new research reported today at the Alzheimer's Association 2009 International Conference on Alzheimer's Disease (ICAD 2009) in Vienna.

Different segments of the carotid artery that supply the brain with blood respond in different fashions to the build-up of complex, health-threatening plaque, according to researchers from Wake Forest University Baptist Medical Center and their colleagues. [More]

Using magnetic resonance imaging (MRI), radiologists may be able to diagnose deep endometriosis and accurately locate lesions prior to surgery, according to a new study published in the online edition of Radiology. [More]

Pancreatic cancer has a devastatingly low survival rate (less than 5 percent after 5 years) because it is usually diagnosed at an advanced stage. The initial symptoms, such as pain, jaundice, or weight loss, often do not allow the disease to be caught early enough for surgery and chemotherapy to be effective. [More]

Parts of the right hemisphere of the brains of people with dyslexia have been shown to differ from those of normal readers. Researchers writing in the open access journal BMC Neuroscience used magnetic resonance imaging (MRI) to compare the two groups, and were able to associate the neurological differences found with different language difficulties within the dyslexic group. [More]

The Magnetic Resonance Center of the University Children's Hospital Zurich has achieved a world first break through in MR-guided, non-invasive neurosurgery. Ten patients have been successfully treated by means of transcranial high-intensity focused ultrasound. This fully non-invasive procedure opens new horizons for neurosurgery and the treatment of different neurological brain disorders. [More]

A recent neuroimaging study reveals that the ability to distinguish true from false in our daily lives involves two distinct processes. Previous research relied heavily on the premise that true and false statements are both processed in the left inferior frontal cortex. [More]

A prototype breast imaging system combining positron emission tomography (PET) and magnetic resonance imaging (MRI) technologies could greatly improve breast cancer imaging capabilities, according to researchers at SNM's 56th Annual Meeting. [More]

A simple magnetic resonance imaging (MRI) test involving breathing oxygen might help oncologists determine the best treatment for some cancer patients, report researchers at UT Southwestern Medical Center. [More]
