Dual-mode nanoparticles image tumors using MRI and PET

Medical imaging represents one of the most used and useful procedures in the oncologist's diagnostic toolkit, even though each of the most useful techniques-magnetic resonance imaging (MRI), computerized tomography x-ray imaging (CT), and positron emission tomography (PET) scanning-has its own set of limitations.

PET scans spot signs of early Alzheimer's

Scientists in Finland say a type of imaging technique known as positron emission tomography (PET) scanning may be a useful and non-invasive way of diagnosing the early stages of Alzheimer’s disease.

Markers in blood and spinal fluid, and a new imaging agent, show promise for early detection of Alzheimer's

With the continued aging of the population and the growing epidemic of Alzheimer's, early detection of the disease is crucial for risk assessment, testing new therapies, and eventual early intervention with better drugs, once they are developed. Four studies reported today at the Alzheimer's Association's 2008 International Conference on Alzheimer's Disease (ICAD 2008) in Chicago bring us closer to that goal of early detection by describing advances in biomarkers.

Oily fish protect Japanese men against clogged arteries

If you're fishing for ways to reduce the risk of heart disease, you might start with the seafood-rich diet typically served up in Japan. According to new research, a lifetime of eating tuna, sardines, salmon and other fish appears to protect Japanese men against clogged arteries, despite other cardiovascular risk factors.

PET-CT scanners detect secondary head and neck cancers

For patients with head and neck cancer, accurately determining how advanced the cancer is and detecting secondary cancers usually means undergoing numerous tests - until now.

Study shows promising results in deep brain stimulation for treatment-resistant depression

New data from a study of patients with treatment-resistant depression who underwent deep brain stimulation (DBS) in the subcallosal cingulate region (SCG or Cg25) of the brain shows that this intervention is generally safe and provides significant improvement in patients as early as one month after treatment. The patients also experienced continued and sustained improvement over time.

Researchers locate and image prostate cancer as it spreads to lymph nodes

Using an engineered common cold virus, UCLA researchers delivered a genetic payload to prostate cancer cells that allowed them, using Positron Emission Tomography (PET), to locate the diseased cells as they spread to the lymph nodes, the first place prostate cancer goes before invading other organs.

New 3-D object recognition and image processing technology to detect cancer

Technology which will make it possible to semi-automate the process for detecting cancerous tumours more precisely is being developed by academics at the University of Hertfordshire.

Radioactive "tag" added to formaldehyde helps monitor body chemistry, disease

Scientists at the U.S. Department of Energy's Brookhaven National Laboratory have devised a simple, fast method for adding a radioactive "tag" to formaldehyde, a common organic chemical.

Weight loss program or exercise, which is best?

In the first study of its kind, using sophisticated methods to measure body composition, the nationally known commercial weight loss program, Weight Watchers, was compared to gym membership programs to find out which method wins in the game of good health.

Report says cancer clinicians should understand and consider the economic impact of new interventions

Cancer clinicians should understand and consider the economic impact of new interventions, which often have substantial costs, according to a report appearing in the July/August issue of CA: A Cancer Journal for Clinicians, a peer-reviewed journal of the American Cancer Society.

Coronary arterial calcium scans help detect overall death risk in the elderly

Measuring calcium deposits in the heart's arteries can help predict overall death risk in American adults, even when they are elderly, according to a new study published in the July issue of Journal of the American College of Cardiology.

ETH Zurich and IBM improve diagnosis of osteoporosis

With the goal of developing an accurate, powerful and fast method to automate the ana-lysis of bone strength, scientists of the ETH Zurich Departments of Mechanical and Pro-cess Engineering and Computer Science teamed up with supercomputing experts at IBM's Zurich Research Laboratory. The breakthrough method developed by the team combines density measurements with a large-scale mechanical analysis of the inner-bone microstructure.

Adult stem cells improve healing of broken bones

Adult stem cells improve healing of broken bones and could eventually serve as a new treatment for the 10 to 20 percent of fractures that fail to heal, according to a new study. The results were presented Monday, June 16, at The Endocrine Society's 90th Annual Meeting in San Francisco, by Froilan Granero-Molto, PhD, research associate of the University of North Carolina.

Individualized therapies for non-Hodgkin's lymphoma identified with PET

Positron emission tomography (PET) could be an important tool for identifying non-Hodgkin's lymphoma patients who are likely to respond well to treatment with 90 ibritumomab tiuxetan (IT)-the first radioimmunotherapy treatment approved for use by the U.S. Food and Drug Administration, said researchers at the Society of Nuclear Medicine's 55th Annual Meeting.

Molecular imaging helps follow the progression of Alzheimer's disease

In the past, physicians were able only to follow the progression of Alzheimer's disease (AD) through careful clinical histories, noting the often subtle changes associated with cognitive decline over a number of years.

Combined PET and CT could be valuable noninvasive tool for determining stages of ovarian cancer

Combined positron emission tomography (PET) and computed tomography (CT) scanning of patients in the early stages of ovarian cancer can enable physicians to determine whether the cancer has spread to nearby lymph nodes without having to perform surgery, according to researchers at the Society of Nuclear Medicine's 55th Annual Meeting.

ExpIND process speeds Alzheimer's drug research

Researchers are actively cutting the time and cost it normally takes to develop radiopharmaceuticals by taking advantage of "Exploratory Investigational New Drug" (ExpIND), an FDA-sanctioned procedure that enhances post-discovery drug development while observing scientific and patient safety standards.

Study recommends development of standards for pediatric doses in nuclear medicine

Results of a recent survey of 13 pediatric hospitals in North America show a lack of universally applied standards for administering radiopharmaceutical doses to children undergoing nuclear medicine examinations, according to an article in the June issue of The Journal of Nuclear Medicine.

Computed tomography lung cancer screening no cure-all for smokers

Screening for lung cancer with computed tomography (CT) may help reduce lung cancer deaths in current and former smokers, but it won't protect them from other causes of death associated with smoking, according to a new study published in the July issue of the journal Radiology.
