Diagnostic Imaging

Radiologists use diagnostic imaging to non-invasively look inside the body to help determine the causes of an injury or an illness, and confirm a diagnosis. Providers use many imaging modalities to do so, including CT, MRI, X-ray, Ultrasound, PET and more.

Radiologist accuracy takes a hit overnight, especially with advanced imaging exams
Serious discrepancies between preliminary imaging reads and final radiology reports are at risk of accumulating when the prelims are rendered during overnight hours.
Appropriate use of imaging proven teachable during medical ed
Radiology education researchers have created an image-intensive online course for third- and fourth-year medical students wishing to learn radiology remotely.
Interpretive AI for medical imaging: 5 points of skepticism, idealism
Surveying the landscape of interpretive AI in radiology, two researchers note a yawning gap between great expectations set in the recent past and actual clinical implementations as of spring 2023.
Diagnosing osteomyelitis with abbreviated noncontrast MRI protocols
Using abbreviated MRI protocols for pediatric exams offers similar quality as standard protocols but decreases the need for sedation.
Solar cell materials could make medical imaging safer, more cost-effective
Not only could the materials reduce patient exposure to ionizing radiation, they also could reduce costs associated with traditional X-ray equipment, according to newly published research in Nature Communications.

Many new imaging solutions were on display at the world's largest health informatics conference, held at McCormick Place in Chicago.

The Nanox ARC cold-cathode, tomosynthesis 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 to 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.

The University of Southern California was among the first imaging centers in the U.S. to install a 7T MRI. This high-end part of the MRI market is small and is mainly made up of academic research centers. The main MRI market is made of of 1.5T systems, but there is rising demand for 3T, which Signify research may eventually become the standard for MRI.

Top MRI trends include helium-free systems, compressed sensing and AI
