X-ray

Medical X-rays have mostly converted from film, to computed radiography (CR) that used individual plates to record each X-ray digitally that then had to be uploaded into a PACS, to what is the standard-of-care today with digital radiography (DR). DR X-ray which allows immediate digital transfer of images into a PACS for immediate review. X-rays are used to diagnose fractures, bone abnormalities, lung pathologies and tumors, as well as monitor pediatric growth, plan for surgery and treat oncology patients during radiation therapy. More detailed anatomical imaging, especially soft tissue imaging, is usually sent for advanced imaging with CT or MRI. X-ray, especially mobile DR systems, are a primary use case for artificial intelligence (AI) integration.

New AI model calculates risk of heart attack or stroke using a single X-ray

“This type of screening could be used to identify individuals who would benefit from statin medication but are currently untreated," one specialist said. The full analysis will be presented at RSNA 2022 in Chicago. 

The Nanox ARC cold-cathode, tomosythesis 3D X-ray system is currently pending FDA clearance. If cleared, it would be the first device of its kind to offer cold-cathode X-ray tube technology and the ability to slice through the anatomy in images similar to CT scans aid diagnosis. The new type of tube also could greatly reduce the size and weight of X-ray systems. The vendor sees this system as key to its larger plan to address health disparities and access to imaging world-wide. #Nanox

Can cold-cathode X-ray combined with teleradiology and AI eliminate health disparities?

The Israeli vendor Nanox says it has a vision for the future of healthcare. It seeks to address health disparities and access challenges with a new business model and innovative package of technologies. Hurdles loom, but opportunities abound. 

X-rays may suffice for assessing some low-back fractures

It’s unlikely radiography will unseat MRI for routinely distinguishing between acute and chronic compression fractures of the lumbar vertebrae, but certain X-ray findings might, in cases, obviate the need for the pricier imaging option.

‘Radiology failures, misdiagnosed fractures’ blamed in 2 wrongful assumptions of child battery

In the U.K., two instances of evidently inept work by radiologists are inadvertently spotlighting the value of subspecialized image interpretation in socially sensitive patient cases.

Mr. O’Lear receives his sentence: 15 years and $2M

The criminal saga of the X-ray business owner who got caught fleecing CMS of $2 million—while grabbing for another $1.7 million or so—has reached its epilogue.

On review, popular imaging decision aid earns 1 thumbs-up—with caveats

With 91% sensitivity but only 25% specificity, the tool is worthwhile for clinicians who remain wary of frequent false positives that would send patients with no fractures for unneeded imaging.

Self-supervised AI ‘reads’ radiology reports to speed algorithm development

A machine learning system has come along that needs no human labeling of data for training yet matches radiologists at classifying diseases on chest X-rays—including some that the model was not specifically taught to detect.

FDA clears X-ray system that produces hi-rez cine loops for chiropractors

Konica Minolta Healthcare has received FDA’s go-ahead to market a dynamic digital radiography (DDR) system.

The patient, who was being cared for in the ICU, was not accompanied or monitored by nursing staff during his exam, despite being sedated.

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.
