PET images of microglial activation levels could better predict Alzheimer's disease progression

Researchers have discovered a way to better predict progression of Alzheimer's disease. By imaging microglial activation levels with positron emission tomography, researchers were able to better predict progression of the disease than with beta-amyloid PET imaging, according to a study published in the April issue of the Journal of Nuclear Medicine.

Expanding range and functionality of radiotracers for improved disease diagnosis

Biomedical imaging has revolutionized medicine, granting doctors a window into miniscule molecular and cellular processes inside the body. An EU-funded project helped to expand the view, developing innovative radiochemistry concepts and techniques that could lead to earlier diagnosis of diseases - saving lives.

Radiolabeled protein lights up tumor to reveal where cancer drugs are working

Experimenting with mice, Johns Hopkins researchers report they have successfully used positron emission tomography scans to calculate in real time how much of an immunotherapy drug reaches a tumor and what parts of a cancer remain unaffected.

Blunting emotional component associated with pain

Chronic pain involves more than just hurting. People suffering from pain often experience sadness, depression and lethargy. That's one reason opioids can be so addictive -- they not only dampen the pain but also make people feel euphoric.

Sleep apnea could be linked to accumulation of Alzheimer’s disease biomarker

People with sleep apnea may be more likely to have higher accumulations of an Alzheimer’s disease biomarker called tau, according to a study presented at the American Academy of Neurology.

Sleep apnea may be related to higher accumulation of Alzheimer's biomarker in the brain

People who are witnessed by a bed partner to have stopped breathing during sleep may have higher accumulations of an Alzheimer's disease biomarker called tau in an area of the brain that helps with memory, according to a preliminary study released today that will be presented at the American Academy of Neurology's 71st Annual Meeting in Philadelphia, May 4 to 10, 2019.

Cavitation dose painting technique: A new method for precise drug delivery

If traditional drug delivery were a type of painting, it might be akin to paintball. With good aim, a majority of the paint ends on the bullseye, but it also drips and splashes, carrying streams of paint across the target.

Pioneering trial offers hope for patients with Parkinson’s disease

In a pioneering new clinical trial, researchers have succeeded in delivering a cell-restoring drug directly to the brains of patients with Parkinson’s disease.

Study finds neuromelanin-sensitive MRI as potential biomarker for psychosis

Researchers have shown that a type of magnetic resonance imaging -- called neuromelanin-sensitive MRI is a potential biomarker for psychosis.

New PET imaging agent may help measure efficacy or failure of hormone therapy for breast cancer

Physicians may soon have a new way to measure the efficacy or failure of hormone therapy for breast cancer patients, according to new research published in the February issue of The Journal of Nuclear Medicine.

Advanced scan shows brain inflammation related to post-treatment Lyme disease syndrome

More than 1 in 10 people successfully treated with antibiotics for Lyme disease go on to develop chronic, sometimes debilitating, and poorly understood symptoms of fatigue and brain fog that may last for years after their initial infection has cleared up.

PET imaging post-HBOT shows improvement in brain metabolism in Alzheimer’s disease

Dr. Paul Harch, Clinical Professor and Director of Hyperbaric Medicine at LSU Health New Orleans School of Medicine, and Dr. Edward Fogarty, Chairman of Radiology at the University of North Dakota School of Medicine, report the first PET scan-documented case of improvement in brain metabolism in Alzheimer's disease in a patient treated with hyperbaric oxygen therapy.

Researchers get close to developing elusive blood test for Alzheimer's disease

People with symptoms of Alzheimer's disease, such as cognitive difficulties, behavior changes and mood swings, may wait months or even years to get a definitive diagnosis. That's because doctors lack a simple, accurate and inexpensive test for it.

New nuclear medicine method could improve detection of primary and metastatic melanoma

A new nuclear medicine method for detecting malignant melanoma, one of the most aggressive skin cancers, has been successfully tested for the first time in humans and could improve detection of both primary and metastatic melanoma.

GE Healthcare and VUMC announce partnership to enable safer, more precise cancer immunotherapies

GE Healthcare and Vanderbilt University Medical Center today announced a five-year partnership to enable safer and more precise cancer immunotherapies. Multiple diagnostic tools will be developed to help predict both the efficacy of an immunotherapy treatment and its adverse effects for a specific patient before the therapy is administered.

Study suggests dopamine release in the brain occurs twice per meal

We know a good meal can stimulate the release of the feel-good hormone dopamine, and now a study in humans from the Max Planck Institute for Metabolism Research in Germany suggests that dopamine release in the brain occurs at two different times: at the time the food is first ingested and another once the food reaches the stomach.

Traditional and new imaging methods used for prostate cancer diagnosis

Prostate cancer is the second prevent type of cancer that exists. Prostate cancer is usually a slowly progressing disease but it can sometimes manifest as an aggressive cancer. Prostate imaging is the primary way to diagnose the disease and this necessity drives its demand in the clinic.
