Research explains why opioids are thought to be ineffective in people with fibromyalgia

People who have the common chronic pain condition fibromyalgia often report that they don't respond to the types of medication that relieve other people's pain.

MicroPET-based biodistribution of quantum dots in living mice

A wide variety of experiments have shown that nanoscale quantum dots have the potential to detect early-stage cancer and even monitor the progress of anticancer therapies.

PET scans accurately detect a breast tumor's response to chemotherapy

Researchers in Australia have shown that positron emission tomography (PET) that uses a radioactive sugar molecule is more useful than mammography and ultrasound in predicting a breast tumour's response to chemotherapy and, therefore, the patient's ultimate likelihood of survival.

Test for lung cancer looks for discomforting quiet among protective genes

When it is quiet – "almost too quiet" – in movies, it is a sign that something is about to go wrong for the good guys.

New guidelines to diagnose Alzheimer's disease

Physicians may be able to detect and treat Alzheimer's Disease (AD) in its earliest stages, when patients are experiencing only mild degrees of cognitive impairment, thanks to new diagnostic criteria proposed by an international group of researchers.

Effectiveness of sinus irrigation in chronic sinusitis

Nasal irrigation has been widely used by rhinologists in treating sinonasal diseases.

Positron emission tomography reliably identifies dangerous cervical tumors

It doesn't matter how small or large it is, if a cervical tumor glows brightly in a PET scan, it's apt to be more dangerous than dimmer tumors.

Most comprehensive recommendations related to lung cancer

New evidenced-based guidelines from the American College of Chest Physicians (ACCP) recommend against the use of low-dose computed tomography (LDCT) for the general screening of lung cancer.

Nuclear medicine approach can be first choice for excluding pulmonary embolism in young women

Young women at risk of having a pulmonary embolism - a potential life-threatening blockage in a lung artery - should first undergo a ventilation/perfusion lung scan (V/Q scan) rather than a CT (computed tomography) angiogram, conclude authors in a paper published in the September Journal of Nuclear Medicine.

Laser technology detects cancer by scanning surface veins

A new technology for cancer detection that eliminates the need for drawing blood has been developed by Purdue University researchers.

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.
