Radiology News and Research

RSS

Radiology is the medical specialty directing medical imaging technologies to diagnose and sometimes treat diseases. Originally it was the aspect of medical science dealing with the medical use of electromagnetic energy emitted by X-ray machines or other such radiation devices for the purpose of obtaining visual information as part of medical imaging.

Insurance coverage of CT colonography and other USPSTF-recognized tests could help fight CRC

Final United States Preventive Services Task Force (USPSTF) colorectal cancer screening recommendations assigned an "A" grade to colorectal cancer (CRC) screening in those ages 50-75 years and provided a list of recognized screening exams.

Brain's reward system in obese people operates differently in response to food and dopamine

As young people reach adulthood, their preferences for sweet foods typically decline. But for people with obesity, new research suggests that the drop-off may not be as steep and that the brain's reward system operates differently in obese people than in thinner people, which may play a role in this phenomenon.

PET imaging can help identify autoimmune inflammation in MS

The triggers of autoimmune inflammation in multiple sclerosis (MS) have eluded scientists for many years, but molecular imaging is bringing researchers closer to identifying them, while providing a means of evaluating next-generation therapies for MS, say researchers introducing a study at the 2016 Annual Meeting of the Society of Nuclear Medicine and Molecular Imaging.

New technique helps identify link between fatty acids and breast cancer in postmenopausal women

The presence of high saturated fatty acids in breast tissue may be a useful indicator of cancer in postmenopausal women, according to a new study by researchers at NYU Langone Medical Center, published online June 7 in Radiology, a journal of the Radiological Society of North America.

RSI-MRI imaging technology can effectively differentiate aggressive prostate cancer

Physicians have long used magnetic resonance imaging (MRI) to detect cancer but results of a University of California San Diego School of Medicine study describe the potential use of restriction spectrum imaging (RSI) as an imaging biomarker that enhances the ability of MRI to differentiate aggressive prostate cancer from low-grade or benign tumors and guide treatment and biopsy.

Researchers detect blood-brain barrier leakage in people with early AD using contrast-enhanced MRI

Researchers using contrast-enhanced MRI have identified leakages in the blood-brain barrier (BBB) of people with early Alzheimer's disease (AD), according to a new study published online in the journal Radiology. The results suggest that increased BBB permeability may represent a key mechanism in the early stages of the disease.

Study explores history of penumbra in untreated acute stroke patients

Radiological imaging is being used more often to evaluate stroke diagnosis and outcomes, with penumbra, or tissue that is at risk of progressing to dead tissue but is still salvageable if blood flow is returned, as a potential target for therapy.

Early diagnosis of lung cancer can increase survival rate by 73%

The UK Lung cancer screening trial (UKLS) has been successfully completed and demonstrated that patients with a high risk of developing lung cancer can be identified with early stage disease and have up to a 73% chance of surviving for five years or more. The UKLS trial was conducted by experts in the University of Liverpool.
