This exemption of certain unclassified medical devices from 510(k) requirements aims to achieve two goals: decrease regulatory burdens on the medical device industry and reduce costs required to comply with federal regulations, while allowing patients continued access to medical devices.

Visually assessing diffusion-weighted imaging (DWI) infarct volumes proved to be inaccurate and, when using DAWN criteria, would have led to wrong decisions on thrombectomy in 19 percent of cases, according to a recent study in the Journal of NeuroInterventional Surgery.

A contract dispute between Chattanooga, Tennessee-based Erlanger Health System and Tennessee Interventional and Imaging Associates (TIAA) is threatening to upend the hospital’s premiere stroke program, according to documents obtained by the Times Free Press.

An international group of researchers found evidence of unique patterns of brain activity that may explain the neurological difference between consciousness and unconsciousness, according to a Feb. 6 study published in Science Advances.

Electronic medical records (EMRs) contain mounds of valuable, but unformatted information making it difficult to use as a source for research, wrote first author, Changhwan Lee, with Hanyang University in Seoul, Korea, and colleagues.  AI may be able to solve that problem.

In a special report published Jan. 30 in the inaugural issue of Radiology: Artificial Intelligence, Luciano M. Prevedello, MD, and colleagues recognize the challenges of implementing AI into clinical workflows, but also offer potential solutions—specifically image-based competitions—which could foster faster, more collaborative AI research.

The authors of a recent Academic Radiology study surveyed 51 interventional and diagnostic radiology program directors across the country to get a better idea of how programs are recruiting medical students.

Researchers used in vivo, two-photon imaging to identify a blood-clotting protein responsible for destroying the synapses in the brain—a precursor to cognitive decline, according to a Feb. 5 study published in Neuron.

An MRI-guided strategy for treating patients with rheumatoid arthritis (RA) showed no benefits over conventional treat-to-target approaches, according to a Feb. 5 study published in JAMA. The authors also found the modality showed no benefit in radiographic progression.

“This case emphasized the importance of a high index of suspicion in an unusual presentation of a common disease and the pivotal role of bronchoscopic intervention in malignant central airway obstruction,” Abdul Hanif Khan, MD, and colleagues wrote, in a new case report published by The BMJ.

Researchers found that combining iodine-123 metaiodobenzylguanidine (123I-MIBG) SPECT imaging with cardiac MRI helped identify specific subsets of heart tissue more prone to arrhythmia, or an irregular heartbeat, according to research published in the January issue of The Journal of Nuclear Medicine.  

A study investigating the differences between healthy brains and those with Alzheimer’s disease (AD) has produced a map of more than 24,000 AD-related datapoints, according to authors of the research published Feb. 4 in Communications Biology. They claim it is one of the largest datasets of its kind.
