Artificial Intelligence

Artificial intelligence (AI) is becoming a crucial component of healthcare to help augment physicians and make them more efficient. In medical imaging, it is helping radiologists more efficiently manage PACS worklists, enable structured reporting, auto detect injuries and diseases, and to pull in relevant prior exams and patient data. In cardiology, AI is helping automate tasks and measurements on imaging and in reporting systems, guides novice echo users to improve imaging and accuracy, and can risk stratify patients. AI includes deep learning algorithms, machine learning, computer-aided detection (CAD) systems, and convolutional neural networks.

Advanced MRI mapping spots traces of gadolinium in the brain invisible during conventional scanning

Radiologists from South Korea found tissue changes associated with repeated gadobutrol injections visible on quantitative susceptibility mapping, but not standard T1-weighted imaging.

COVID-19 brain abnormalities on MRI in patients with neurological symptoms

There is growing evidence that, in addition to attacking patients’ lungs, the coronavirus also targets the central nervous system, with new research adding weight to this hypothesis.

Unresponsive COVID-19 patients have a better neurological prognosis than expected

Resting-state functional MRI showed restored connections in a brain region critical to consciousness, and the 47-year-old patient gained further function in the following weeks.

Brain iron buildup is associated with cognitive decline in Alzheimer’s patients

The MRI findings may push treatment research toward drugs that eliminate excess iron from the body, commonly known as chelators.

Hospital alerts radiologists of new post-COVID-19 disease appearing in children

Evelina London Children's Hospital recently experienced an "unprecedented cluster" of a new condition known as Multisystem Inflammatory Syndrome in Children, and is warning it's imaging colleagues in the U.S. to be on the lookout.

New $40.5M research center dedicated to mapping Alzheimer’s disease

Investigators at the Seattle-based Allen Institute hope to determine how and where the disorder begins and identify new brain cells that are most vulnerable at the onset of the disease.

Around the web

Positron, a New York-based nuclear imaging company, will now provide Upbeat Cardiology Solutions with advanced PET/CT systems and services. 

The nuclear imaging isotope shortage of molybdenum-99 may be over now that the sidelined reactor is restarting. ASNC's president says PET and new SPECT technologies helped cardiac imaging labs better weather the storm.

CMS has more than doubled the CCTA payment rate from $175 to $357.13. The move, expected to have a significant impact on the utilization of cardiac CT, received immediate praise from imaging specialists.
