Cardiac ultrasound imaging goes handheld

Non-invasive imaging has revolutionized the diagnosis of the most common cardiac diseases such as valve problems and coronary heart disease. In addition, imaging techniques are developing rapidly and we anticipate that non-invasive imaging will gain further importance in the treatment of cardiac patients.

New molecular imaging techniques aim at detection of earliest steps of disease development

An emerging discipline of noninvasive cardiac imaging, molecular imaging, has evolved constantly in the last few years and is increasingly being translated from the preclinical to the clinical level.

Ongoing debate: The future of non-invasive cardiac imaging

Imaging has gained attention in many areas of medicine but its relevance and importance in clinical cardiology cannot be underestimated.

Hormone deprivation therapy - used for prostate cancer - may cause recall and concentration problems

A recent review of the literature has found that hormone deprivation therapy, a commonly used treatment for prostate cancer, may have subtle adverse effects on cognition in patients--such as in the ability to recall and concentrate.

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.

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.

Neuroscientists pinpoint how neural activity boosts blood flow to the brain

New research from Harvard University neuroscientists has pinpointed exactly how neural activity boosts blood flow to the brain. The finding has important implications for our understanding of common brain imaging techniques such as fMRI, which uses blood flow in the brain as a proxy for neural activity.

Noninvasive molecular imaging technology helps track stem cells in tumors

Using noninvasive molecular imaging technology, a method has been developed to track the location and activity of mesenchymal stem cells (MSCs) in the tumors of living organisms, according to researchers at the Society of Nuclear Medicine's 55th Annual Meeting. This ability could lead to major advances in the use of stem cell therapies to treat cancer.

Gene radiotherapy system shows promise for fighting treatment-resistant cancer cells

A gene radiotherapy system that detects and treats cancer cells that are resistant to traditional forms of chemotherapy and radiation showed success in the laboratory and could eventually prove beneficial for cancer patients, according to researchers at the Society of Nuclear Medicine's 55th Annual Meeting.

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.

New model predicts whether patients will be free of renal cancer 12 years after initial treatment

A UT Southwestern Medical Center physician and other researchers have developed a unique statistical model that predicts the probability of a patient being cancer free 12 years after initial surgical treatment.

Quality of life predicts cancer survival

Head and neck cancer patients who reported lower physical quality of life were more likely to die from their disease, according to a new study from the University of Michigan Comprehensive Cancer Center. The findings could mean that identifying patients with poor quality of life could also identify patients with particularly aggressive tumors.

Study looks at phantom limb syndrome

Losing a limb can be a traumatic experience and, in some cases, emotional and physical pain can linger for years. To better understand the phenomenon, dubbed "phantom limb syndrome," Université de Montreal graduate student Emma Duerden is inviting amputees to come forward and share their experiences for a major study.

Fruit fly avoidance mechanism could lead to new ways to control pain in humans

At first, fruit flies eat like horses. Hatching inside over-ripe fruit where they were laid, they feed wildly in the sugar-rich environment until nature sends them an offer they can't refuse. To survive, they must leave the fruit, wander off and burrow into the earth where they avoid food as if it were poison. Only then can the larvae grow and hatch into flies that will take wing to lay their own eggs.

Scientists explore brain's reaction to potent hallucinogen

Brain-imaging studies performed in animals at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory provide researchers with clues about why an increasingly popular recreational drug that causes hallucinations and motor-function impairment in humans is abused.

Brain tumor care, treatment in spotlight

Patients, physicians, and those caring for loved ones with brain tumors will have an opportunity to attend two full days of programs hosted by health care professionals from the University of Rochester Medical Center.

Biomarkers may reduce the need for biopsies and personalize transplant patient care

Data presented at the 28th Annual Meeting and Scientific Sessions of the International Society for Heart and Lung Transplantation (ISHLT) suggest the potential of a significant impact of using biomarkers to reduce the need for biopsies and personalize transplant patient care.

MRI opens up promising new avenues for non-invasive diagnoses and classification of cancer

Doctors diagnose and prescribe treatment for brain tumors by studying, under a microscope, tumor tissue and cell samples obtained through invasive biopsy or surgery.

New robotic interventional imaging technology holds promise of improved cancer care

New research released at the Society of Interventional Radiology's (SIR) Annual Scientific Meeting in Washington, D.C., this week, holds promise of a new interventional imaging capability using advanced robotics provided by Siemens Healthcare (www.siemens.com/healthcare), to improve the value of chemoembolization in treating cancer.
