Patient exposure to radiation during coronary CT angiography (CTA) has dropped nearly 80% over the last 10 years, largely because of innovations in technique allowed by hardware and software advances, suggests a new installment in a series of surveys documenting these changes.
A simple enhanced ultrasound scan of the kidney is more accurate than computed tomography (CT) and magnetic resonance (MR) imaging in predicting whether suspicious masses are cancerous.
A study by a Massachusetts General Hospital (MGH) research team finds that neurogenesis -inducing the production of new neurons—in the brain structure in which memories are encoded can improve cognitive function in a mouse model of Alzheimer's disease
While emotions such as anger or sadness are often thought of as being a result of stress or pain, findings recently published by Penn State researchers suggest that negative or mixed emotions could function as stressors themselves
RUDN biochemists suggested a new mechanism by which the human body prevents the development of autoimmune diseases, allergies, and implant rejection. They report that regulatory T-cells are able to suppress the reproduction of autoimmune cells. The work was published in Molecular Immunology
The tiniest of premature infants—weighing just over two pounds at birth on average—start out receiving nutrition intravenously. Over the next several days or weeks, they are transitioned to enteral (or through the gut) feeds, often delivered through feeding tubes if the baby still cannot suck or swallow
Two-thirds of women with type 2 diabetes mellitus (T2DM) have low bone mass and deteriorated microarchitecture, according to the new findings
Around six years ago, high-resolution optical coherence tomography (OCT) was jointly developed by MedUni Vienna's Center for Medical Physics and Biomedical Technology and its Department of Ophthalmology. OCT is an imaging technique that, like ultrasound – but contact-free – displays accurate stratified images of the retina
New "Guidelines for the Evaluation and Treatment of Perimenopausal Depression: Summary and Recommendations have been co-published in Journal of Women's Health and Menopause: The Journal of The North American Menopause Society
Prostate-specific membrane antigen (PSMA) positron emission tomography (PET) imaging has become a popular method for determining the stage of a patient's prostate cancer. However, researchers have identified a major pitfall in this imaging technique and are cautioning medical professionals to be aware of the potential for misdiagnosis when relying solely on PSMA PET
By developing a novel decoding technology, a team of engineers and physicians at the University of Southern California (USC) and UC San Francisco have discovered how mood variations can be decoded from neural signals in the human brain—a process that has not been demonstrated to date
Acute critical illness in people without previous renal disease puts them at risk of kidney complications as well as death, according to a study published in CMAJ (Canadian Medical Association Journal)
