Researchers create model to calculate bone density and elasticity with CT scan images

Artificial hip joints are firmly anchored to the patient's damaged bone by screws. But which parts of the bone will safely hold the screws in place? A simulation model is to calculate the strength of the bone from computer tomography images.

Stents can be placed in the brain to treat a stroke as it's occurring

Stents can be placed in the brain to treat a stroke as it's occurring, suggests preliminary data being presented at the 21st Annual International Symposium on Endovascular Therapy (ISET).

Biodegradable nanoprobe images new blood vessel growth

Angiogenesis, the growth of new blood vessels, plays a critical role in several chronic human diseases, including metastatic cancer. In fact, several new anticancer therapies are designed to starve tumors by shutting down angiogenesis, but the lack of a good assay for quantifying angiogenesis in the body has hampered the development of effective antiangiogenesis therapies.

Photoacoustic tomography changes lymph node biopsy, reduces radiaiton exposure

Information obtained from a new application of photoacoustic tomography (PAT) is worth its weight in gold to breast cancer patients.

Innovative brain-scan technology helps visualize brain aging before symptoms appear

UCLA scientists have used innovative brain-scan technology developed at UCLA, along with patient-specific information on Alzheimer's disease risk, to help diagnose brain aging, often before symptoms appear.

Scientists find new way to 'track' response to cancer drugs

Scientists have found a new way of accurately measuring the success of experimental cancer drugs, according to a study published in Cancer Research.

Appropriate use criteria for coronary revascularization

If you're committed to fitness, the decision to climb a couple of flights of stairs rather than take the elevator is clear. But if you develop chest pain on the way up, deciding how to treat the symptoms of clogged arteries in your heart is much more complicated.

MRI scans emerge as vital resource in treatment of back pain

Magnetic resonance imaging (MRI) is a growing technology providing an increasing number of clinical benefits when used in the evaluation of back pain according to an article in the January 2009 issue of the Journal of the American Academy of Orthopaedic Surgeons.

Molecular imaging enables earlier, individualized treatment of thyroid cancer

In a study to determine the diagnostic value of molecular imaging in nodal staging of patients with thyroid cancer, researchers were able for the first time to accurately distinguish between cancerous cells in regional lymph nodes and normal residual thyroid tissue directly after surgery.

New insight into the origin of face recognition in humans

Chimpanzees recognize their pals by using some of the same brain regions that switch on when humans register a familiar face, according to a report published online on December 18th in Current Biology, a Cell Press publication.

UC Davis team refines cancer treatments to reduce potential nerve damage

While radiation treatments deliver precise doses of high-energy X-rays to stop cancer cells from spreading or to shrink tumors, oncologists have become increasingly concerned about inadvertent exposures during head and neck cancer treatments to nerves responsible for upper body mobility.

Lung cancer screening feasibility study funded

A study to assess the feasibility of undertaking a UK-based screening trial for lung cancer has been commissioned by the National institute for Health Research Health Technology Assessment (NIHR HTA) programme. Lung cancer kills more people worldwide than any other malignancy accounting for around 1.4 million deaths each year, and around 38,000 individuals are diagnosed with the disease in the UK each year.

Estrogen therapy can help control metastatic breast cancer

For breast cancer survivors, the idea of taking estrogen pills is almost a taboo. In fact, their doctors give them drugs to get rid of the hormone because it can fuel the growth of breast cancer.

Early photon tomography provides clearer picture of tumors in living animals

Fluorescent molecules - i.e. substances which can be stimulated to emit light - are extremely valuable tools in biological research and medical diagnosis.

High phosphorus levels in blood linked to coronary calcification in chronic kidney disease

For patients with moderate chronic kidney disease (CKD), higher levels of phosphorus in the blood are associated with increased calcification of the major arteries and heart valves - which may contribute to the increased risk of cardiovascular disease in patients with CKD, reports a study in the Journal of the American Society of Nephrology (JASN).

Discovery of gene variants that impact the placebo effect

It is a well-known fact in drug trials that individuals can respond just as well to placebos, sugar pills, as to the active drug.

Cancer risk from cardiac computed tomography overstated

Radiology and cardiovascular researchers from the Medical University of South Carolina in Charleston, S.C., today present new data that shows the risk of cancer from exposure to radiation during computed tomography for cardiovascular disease has been overstated and that new estimates are several times lower than previously published conclusions.
