Heading a soccer ball could lead to brain injury
Frequent 'heading' in soccer can lead to brain injury and cognitive impairment, revealed by researchers. Einstein Montefiore research suggests frequency threshold for injury that could lead to safety guidelines.

Low calorie diet improves heart function in diabetic obese patients
A low-calorie diet eliminates insulin dependence and leads to improved heart function in obese patients with type 2 diabetes. It is striking to see how a relatively simple intervention of a very low calorie diet effectively cures type 2 diabetes mellitus. Moreover, these effects are long term.

Children with ADHD may have functional brain pathways disrupted
Some abnormalities in the brains of children with attention deficit/hyperactivity disorder (ADHD) may serve as a biomarker for the disorder, according to a study presented at the annual meeting of the Radiological Society of North America (RSNA).

Screening mammography for breast cancer improved
Researchers analyzing 2.5 million screening mammograms performed on nearly one million women found discrimination of cancerous from non-cancerous lesions improved over a nine-year period. Results of the study are published in the online edition of the journal Radiology.

Blood flows differently through the brains of schizophrenic patients
Researchers in Germany have used a magnetic resonance imaging (MRI) technique called continuous arterial spin labeling (CASL) to map cerebral blood flow patterns in schizophrenic patients quickly and without using radiation or contrast agents. Their findings appear in the online edition and July printed issue of the journal Radiology.

Childhood lead exposure causes permanent brain damage
A study using functional magnetic resonance imaging (fMRI) to evaluate brain function revealed that adults who were exposed to lead as children incur permanent brain injury. The results were presented today at the annual meeting of the Radiological Society of North America (RSNA).

Breast ultrasound can reduce breast biopsies in young women
Targeted breast ultrasound of suspicious areas of the breast, including lumps, is a safe, reliable and cost-effective alternative to invasive biopsies for women under age 40.

Excessive physical activity and exercise may lead to knee osteoarthritis
Middle-aged men and women who engage in high levels of physical activity may be unknowingly causing damage to their knees and increasing their risk for osteoarthritis.

Men and women may respond differently to danger
Men and women respond differently to positive and negative stimuli, revealed by researchers in a study presented at the annual meeting of the Radiological Society of North America (RSNA).

Making imaging procedures safer for patients
The Radiological Society of North America (RSNA) reaffirmed its commitment to patient safety in responding to a study and accompanying perspective on radiation dose from medical imaging procedures in the New England Journal of Medicine (NEJM).

Obesity leads 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.

MRI shows brain atrophy pattern that predicts Alzheimer's Disease
Researchers have identified a pattern of regional brain atrophy in patients with mild cognitive impairment (MCI) that indicates a greater likelihood of progression to Alzheimer's disease. Researchers used special MRI methods.

New breast imaging BSGI effective in detection of breast cancers
Breast-specific gamma imaging (BSGI) is effective in the detection of cancers not found on mammograms or by clinical exam, according to a study presented today at the annual meeting of the Radiological Society of North America (RSNA).

Radiologists diagnose and treat self embedding disorder in teens
Minimally invasive, image-guided treatment is a safe and precise method for removal of self-inflicted foreign objects from the body, according to the first report on "self-embedding disorder," or self-injury and self-inflicted foreign body insertion in adolescents.

New MRI imaging may identify cervical cancer early
Using high-resolution magnetic resonance imaging (MRI) with a special vaginal coil, a technique to measure the movement of water within tissue, researchers may be able to identify cervical cancer in its early stages, according to a new study being published in the November issue of Radiology.
