Benefits and limitations of health tests offered in community settings

Consumers who queue up for health screenings at the mall, a senior center, a drug store or other retail business could benefit from the information they learn.

3D fruit fly images to benefit brain research

The fragile head and brain of a fly are not easy things to examine but MRC scientists have figured out how to make it a little simpler. And they hope their research will shed light on human disease.

Imaging is everything: What the clinician needs to know

In recent years, the concept of multimodality imaging has emerged coincident with advances in the newer technologies of Cardiac Magnetic Resonance (CMR) and Coronary Computed Tomography (CCT).

Near-infrared resonant nanoshells for combined optical imaging and photothermal cancer therapy

Using metal nanoshells designed to both absorb and scatter near-infrared light, a team of investigators at Rice University has shown that such nanoparticles can both image and treat tumors in animals. Their experiments revealed complete tumor destruction in more than 80 percent of animals treated with these nanoshells.

High-density diffuse optical tomography helps scan infant brains

Researchers hoping to better understand the development of the infant brain have long been stymied by a formidable obstacle: babies just don't want to sit still for brain scans.

PET MPI provides a more accurate "picture" of coronary obstruction

Physicians need to know how badly heart vessels are blocked before they can decide how to treat patients at risk of having a heart attack.

First 3D images of a living cell

A new imaging technique developed at MIT has allowed scientists to create the first 3D images of a living cell, using a method similar to the X-ray CT scans doctors use to see inside the body.

High-tech diagnosis pinpoints causes of behavioral and psychiatric problems in patients

Is there a definitive test for mental illness? Not yet, but using advanced neuropsychiatric diagnostic tools including magnetic resonance imaging (MRI) and positron emission tomography (PET), mental health professionals at The Menninger Clinic in Houston are pinpointing the causes of behavioral and psychiatric problems in patients.

Cerebral blood flow provides clues to treating depression

The usefulness of established molecular imaging/nuclear medicine approaches in identifying the hows and whys of brain dysfunction and its potential in providing immediately useful information in treating depression are emphasized in a study in the August Journal of Nuclear Medicine.

Handheld BrainScope device detects brain damage immediately after concussion

Researchers at NYU School of Medicine have developed a handheld device that can detect subtle brain damage immediately after concussion.

ADHD linked to depressed dopamine activity in the brain

Adults with attention-deficit/hyperactivity disorder (ADHD) show a blunted response to the drug methylphenidate (Ritalin), which increases brain dopamine levels, according to a report in the August issue of Archives of General Psychiatry, one of the JAMA/Archives journals.

CT-guided radiofrequency ablation effective in eradicating small malignant kidney tumors

A relatively new, minimally invasive treatment was 100 percent successful in eradicating small malignant kidney tumors in a study of more than 100 patients, report researchers from Wake Forest University Baptist Medical Center.

Imaging technique accurate in aneurysm detection and therapy planning

Multidetector computed tomography (MDCT) angiography is highly accurate in depicting intracranial aneurysms, according to a study published in the August issue of Radiology.

Interferon alpha and sorafenib combined work better than either alone against kidney cancer

A combination of two drugs works better than either drug alone for patients with renal cell carcinoma, the most common form of kidney cancer, according to a pilot study led by Duke University Comprehensive Cancer Center researchers.

The future of Alzheimer's disease research

Imagine the day when a routine visit to the family doctor includes a simple blood test to predict the risk for developing Alzheimer's disease (AD).

PET scans show if radiation is shrinking lung tumors

Lung cancer patients may not need to wait till their radiation treatment is over to know if it worked.

New study explains placebo effect

Why do some people experience a “placebo effect” that makes them feel better when they receive a sham treatment they believe to be real — while other people don't respond at all to the same thing, or even feel worse?

Cancer risk from radiation during cardiac CT scans studied

An analysis based on computerized simulation models suggests that the lifetime risk of cancer associated with radiation exposure from a computed tomography (CT scan) coronary angiography varies widely, with the risk greater for women and younger patients, according to a study in the July 18 issue of JAMA .

Suped-up computed tomography scanners

By borrowing techniques used in telecommunications technology, computed tomography (CT) scanners may eventually see data collection speeds increase by hundreds of times, leading to better images, faster imaging procedures, and potentially lower x-ray exposures.
