FDG-PET technology less accurate in diagnosing lung cancer in regions where infections are common

A new analysis of published studies found that FDG-PET technology is less accurate in diagnosing lung cancer versus benign disease in regions where infections like histoplasmosis or tuberculosis are common. Misdiagnosis of lung lesions suspicious for cancer could lead to unnecessary tests and surgeries for patients, with additional potential complications and mortality.

PET-CT more accurate than conventional CT in evaluating patients with follicular lymphoma

Positron emission tomography/computed tomography (PET-CT) is more accurate than conventional CT scanning in measuring response to treatment and predicting survival in patients with follicular lymphoma, and should be used routinely in clinical practice, according to new research published in The Lancet Haematology.

Study ties eating in response to food cues to habit-forming region in obese adults

People who are obese may be more susceptible to environmental food cues than their lean counterparts due to differences in brain chemistry that make eating more habitual and less rewarding, according to a National Institutes of Health study published in Molecular Psychiatry.

New noninvasive method could lead to better diagnosis, treatment of gut diseases

A multi-institutional team of researchers has developed a new nanoscale agent for imaging the gastrointestinal (GI) tract. This safe, noninvasive method for assessing the function and properties of the GI tract in real time could lead to better diagnosis and treatment of gut diseases.

Noninvasive optical imaging device helps to detect changes linked with Alzheimer's disease

A noninvasive optical imaging device developed at Cedars-Sinai can provide early detection of changes that later occur in the brain and are a classic sign of Alzheimer's disease, according to preliminary results from investigators conducting a clinical trial in Australia.

Eye exam for beta-amyloid correlates with levels in brain, detects people with Alzheimer's

A decreased ability to identify odors might indicate the development of cognitive impairment and Alzheimer's disease, while examinations of the eye could indicate the build-up of beta-amyloid, a protein associated with Alzheimer's, in the brain, according to the results of four research trials reported today at the Alzheimer's Association International Conference- 2014 (AAIC- 2014) in Copenhagen.

EMA CHMP recommends marketing authorization for GE's VIZAMYL for PET imaging to detect beta amyloids

GE Healthcare today announced the receipt of a positive opinion from the European Medicines Agency's Committee for Medicinal Products for Human Use. This opinion recommends the granting of a marketing authorisation for VIZAMYL (Flutemetamol F18 injection), a radiopharmaceutical medicinal product indicated for Positron Emission Tomography imaging of beta amyloid neuritic plaque density in the brains of adult patients with cognitive impairment who are being evaluated for Alzheimer's disease and other causes of cognitive impairment.

Groundbreaking molecular imaging agent developed to trace advanced prostate cancer

Anti-androgen hormonal therapy, also called chemical castration, can be an important defense against further disease progression for patients with prostate cancer that has traveled and grown in other areas, or metastasized-but some cases simply do not respond to this treatment.
