Study shows increase in medical imaging in health maintenance organization systems

Concern about overexposure to radiation due to excessive use of medical imaging has come to the fore in recent years. Now, a study led by researchers at the University of California, San Francisco (UCSF) and Group Health Research Institute, shows that medical imaging is increasing even in health maintenance organization systems (HMOs), which don't have a financial incentive to conduct them.

Ultra-sensitive imaging test can demonstrate link between TBI and PTSD

Even when brain injury is so subtle that it can only be detected by an ultra-sensitive imaging test, the injury might predispose soldiers in combat to post-traumatic stress disorder, according to a University of Rochester Medical Center study.

Scientists develop new low-dose CT-scan technique

Scientists have developed an X-ray imaging method that could drastically improve the contrast of computed tomography (CT) scans whilst reducing the radiation dose deposited during the scan. The new method is based on the combination of the high contrast obtained by an X-ray technique known as grating interferometry with the three-dimensional capabilities of CT.

Imaging of blood flow provides new way to look into cardiac abnormalities and dysfunction

Researchers from Mount Sinai School of Medicine are pioneering new ultrasound techniques that provide the first characterization of multidirectional blood flow in the heart. By focusing on fluid dynamics - specifically, the efficiency with which blood enters and exits the heart's left ventricle - the researchers believe they can detect heart disease even when traditional measures show no sign of trouble.

New method can detect and monitor pH changes in living brains

University of Iowa neuroscientist John Wemmie, M.D., Ph.D., is interested in the effect of acid in the brain. His studies suggest that increased acidity or low pH, in the brain is linked to panic disorders, anxiety, and depression. But his work also suggests that changes in acidity are important for normal brain activity too.

First study to compare complication rates after RAPN and LPN

Robot-assisted surgery has replaced another minimally invasive operation as the main procedure to treat kidney cancer while sparing part of the diseased organ, and with comparable results, according to a new research study by Henry Ford Hospital urologists.

Researchers identify over 2500 mRNA along dendrites and axons

How do we build a memory in the brain? It is well known that for animals (and humans) new proteins are needed to establish long-term memories. During learning information is stored at the synapses, the junctions connecting nerve cells.

IGABT effective at controlling return and spread of cervical cancer

Delivering radiotherapy directly to cancer of the cervix using 3-D imaging techniques is effective at controlling the return and spread of the disease and, in most cases, avoids the need for hysterectomies, according to research presented at the World Congress of Brachytherapy today.

Seed localization improves satisfaction of breast cancer patients

A cutting-edge procedure called seed localization is improving patient satisfaction at The Dubin Breast Center of the Tisch Cancer Institute at The Mount Sinai Medical Center. In patients undergoing lumpectomy for cancers that are small and cannot be felt in the breast, a tiny radioactive seed is guided into the breast and implanted at the site of the tumor.

PDAD patients have much denser accumulations of striatal plaques in the brain

Dementia is a frequent complication of Parkinson's disease (PD), but it is clinically impossible to distinguish PD dementia (PDD), which develops from the progression of the Lewy body pathology that underlies PD, from PD with coexistent Alzheimer's disease.

Two research studies on genetic components of Alzheimer's

Two research studies, co-led by UC Davis neurologist Charles DeCarli and conducted by an international team that included more than 80 scientists at 71 institutions in eight countries, has advanced understanding of the genetic components of Alzheimer's disease and of brain development. Both studies appear in the April 15 edition of the journal Nature Genetics.

Study examines potential impact of policies to reduce inappropriate imaging for prostate cancer

In the current hyper-charged United States healthcare debate, the focus on lowering cost without compromising quality of care remains a priority. But according to a new study by researchers at NYU Langone Medical Center and colleagues, one common approach may have serious unintended consequences.
