Medical Imaging

Physicians utilize medical imaging to see inside the body to diagnose and treat patients. This includes computed tomography (CT), magnetic resonance imaging (MRI), X-ray, ultrasound, fluoroscopy, angiography,  and the nuclear imaging modalities of PET and SPECT. 

Composition of fat in breast tissue has a bearing on cancer risk

NYU-Langone researchers have shown an association between high levels of saturated fat in breast adipose tissue with breast cancer in postmenopausal women.

Non-imaging MR application helps head off sepsis in children

An MR-based system for identifying pediatric cases of Candida infection has been shown capable of using low-volume blood specimens to efficiently diagnose or rule out candidemia, the deadliest form of sepsis-causing bloodstream infection.

Oncology society’s data-analytics subsidiary growing fast

A year and a half after the American Society of Clinical Oncology (ASCO) and software partner SAP announced their CancerLinQ initiative to achieve better cancer care through big data, some 58 practices representing 1,000 providers around the country have signed on and are sharing insights from around 750,000 patient records.

A new weapon is emerging in the war against pancreatic cancer

U.S. and Japanese researchers have come up with a novel, image-based way to track stem cell signals so as to halt pancreatic cancer in its tracks.

Not ready for clinical primetime: 3D tomosynthesis images rendered in 2D

Comparing the quality of synthesized 2D images created using 3D digital breast tomosynthesis (DBT) with the quality of images captured in 2D full field digital mammography (FFDM), a research team at Duke has found that the former is indeed better than the latter at depicting some visual features.

Direct-to-patient study recruitment proves a hit in breast cancer project

Reaching out directly to patients through the Internet, social media and other nontraditional channels, researchers have recruited more than 2,000 participants from across the country for a metastatic breast cancer (MBC) study project launched last fall.

New tumor illuminator in the works

Texas researchers are developing a way to turn the diffusion properties of LED lighting against tumors.   

Diffusion imaging zeroes in on specific prostate-cancer sections

The advanced diffusion-weighted imaging technique RSI, short for restriction-spectrum MRI, is able to detect variations in tumor grade with voxel-level precision—and so could aid in customizing treatment of prostate cancer patients whose disease is spreading faster in some tumor regions than others.  

Around the web

RBMA President Peter Moffatt discusses declining reimbursement rates, recruiting challenges and the role of artificial intelligence in transforming the industry.

Deepak Bhatt, MD, director of the Mount Sinai Fuster Heart Hospital and principal investigator of the TRANSFORM trial, explains an emerging technique for cardiac screening: combining coronary CT angiography with artificial intelligence for plaque analysis to create an approach similar to mammography.

A total of 16 cardiology practices from 12 states settled with the DOJ to resolve allegations they overbilled Medicare for imaging agents used to diagnose cardiovascular disease.
