MRI can cut overdiagnoses in prostate-cancer screening by half
(Karolinska Institutet) Most countries have not introduced nationwide prostate-cancer screening, as current methods result in overdiagnoses and excessive and unnecessary biopsies. A new study by researchers at Karolinska Institutet in Sweden, which is published in The New England Journal of Medicine, indicates that screening by magnetic resonance imaging (MRI) and targeted biopsies could potentially cut overdiagnoses by half. The results are presented today at the European Association of Urology Congress. (Source: EurekAlert! - Cancer)

What Problems are Ciliopathies Associated With?
Discussion
Nephronophthisis (NPHP) one cause of end-stage renal disease (ESRD) usually occurring before age 30 years. NPHP is a non-motile ciliopathy affecting cellular sensing in the renal tubular epithelium. See To Learn More below.
The incidence varies according to location with 1:1 million in the US but 1:50,000 in Finland.
There are 3 subtypes:
Infantile
Occurs usually within 1 year of life
Enlarged kidneys and severe hypertension
In utero can have oligohydramnios problems such as pulmonary hypoplasia, facial dysmorphisms, limb contractures
Extra-renal problems include congenital heart disease, liver fibrosis, recur...

NIST-led study finds variations in quantitative MRI scanners' measurements
(National Institute of Standards and Technology (NIST)) Magnetic resonance imaging (MRI) is widely used in medicine to detect, diagnose and treat diseases such as cancer, while relying on experts' interpretation of images. Quantitative MRI, which obtains numerical measurements during the scans, can now potentially offer greater accuracy, repeatability and speed -- but rigorous quality control is needed for it to reach its full potential, according to a new study.

Flavored e-cigarettes may affect the brain differently than non-flavored
(Penn State) Flavoring can change how the brain responds to e-cigarette aerosols that contain nicotine, according to Penn State College of Medicine researchers. Andrea Hobkirk and her team used functional magnetic resonance imaging (MRI) to understand how the brain's reward areas react to e-cigarette aerosol with and without flavor.
