Screening patients for early lung cancer can be made far more effective by using ancillary blood tests, new research suggests. “Screening by CT saves lives, reducing lung cancer mortality by at least 20%,” noted Stephen Lam, MD, chair, provincial lung tumor group at the British Columbia Cancer Agency in Vancouver, Canada. However, a key issue…

Compared to regular amyloid imaging, fluorodeoxyglucose positron emission tomography (FDG PET), an imaging technique that quantifies brain function by measuring glucose levels, can better assess the progression and severity of cognitive decline in people with Alzheimer’s, and also cognitive impairment, researchers have found. Their study, “18F-FDG Is a Superior Indicator of Cognitive Performance Compared to…

CT scans reveal the dangers of vaping

New research published in the New England Journal of Medicine has linked e-cigarette use to a cluster of respiratory illness cases identified on CT scans. The results add to the growing concern that vaping may cause lung damage, an idea that manufacturers of vaping products have downplayed. The team, led by Jennifer Layden, PhD, chief medical officer of the Illinois Department…

PET scans measuring glucose more effective

A new study has found that PET scans measuring glucose may be a better indicator of the progression of Alzheimer’s disease than amyloid PET scans. As clinical trials targeting beta-amyloid plaques, toxic proteins that form in an Alzheimer’s patient’s brain, continue to fail, some researchers have started focusing their efforts on drugs that could clear…
