Magnetic resonance imaging (MRI) is a unique and versatile medical imaging diagnostic tool. Using MRI, physicians obtain highly refined images of the body’s interior. Strong magnetic fields and pulses of radio waves manipulate the body’s natural magnetic, producing images not possible with other diagnostic imaging methods.
More research on risks and benefits of medical imaging needed – Researchers are evaluating the risks and benefits of medical imaging in patients. They revealed that the average effective dose of radiation nearly double the amount they would otherwise be exposed to from natural sources.
MRI may be unnecessary prior to treatment in most newly diagnosed breast cancer patients — New Study in Journal of the American College of Surgeons Finds Those Who Undergo MRI More Likely to Have Premature Mastectomy. – New research findings published in the August issue of the Journal of the American College of Surgeons challenge the routine use of magnetic resonance imaging (MRI) as a means to improve surgical outcomes in newly diagnosed breast cancer patients.
In the modern post-PSA era, prostate cancer surgery may not be necessary for some patients — Study finds few patients die from prostate cancer within 15 years of radical prostatectomy. – Prostate surgery prostatectomy is found very effective in preventing death in men with aggressive prostate cancers, revealed by researchers at Memorial Sloan-Kettering Cancer Center (MSKCC), Cleveland Clinic and the University of Michigan.

Obesity contributes to rapid cartilage loss – Obesity is strongly associated with an increased risk of rapid cartilage loss, revealed by researchers at Boston University. The study published in the August issue of Radiology.
Mayo Clinic study using structural MRI may help accurately diagnose dementia patients – Researchers developed STAND-Map – a framework for MRI-based differential diagnosis of three common neurodegenerative disorders: Alzheimer’s disease, frontotemporal lobar degeneration, and Lewy body disease using Structural MRI.
Study challenges routine use of MRI scans to evaluate breast cancer — Test is linked to delays in treatment, increase in mastectomy rates. – Women with newly diagnosed breast cancer who receive a breast MRI are more likely to receive a mastectomy after their diagnosis and may face delays in starting treatment, revealed by researchers.
Migraines with aura in midlife associated with increased prevalence of brain lesions in older age – Middle-aged women who had migraine headaches with aura i.e. sensory disturbances, such as with vision, balance or speech, had a higher prevalence of brain lesions when they were older, compared to individuals without similar types of headaches.
Fat to make you feel fuller — UK scientists have designed a fatty formulation that can make you feel fuller for longer. – Scientists have designed a fatty formulation that can make you feel fuller for longer. When the fat remains stable in the acid environment of the stomach, it empties into the small intestine more slowly and increases satiety.
