Dear Digital X-Ray Insider,
A review in April identified more than 460 articles on artificial intelligence (AI) and lung imaging in COVID-19 diagnosis and management, with about 50% of the research involving x-ray -- and there have been more since.
In one such study, researchers from Hong Kong proposed a model in which AI analysis of chest x-rays and blood tests could offer an alternative to reverse transcription polymerase chain reaction (RT-PCR) tests for SARS-CoV-2 infection in regions of the world where resources for identifying SARS-CoV-2 may be scarce.

Plus, here are a few other stories we've covered on x-ray imaging and COVID-19:
- The COVID-19 pandemic has caused anxiety and workplace-related stress among radiologic technologists.
- An AI algorithm may help physicians determine which COVID-19 patients will likely need hospitalization and supplemental oxygen.
AI is showing its utility beyond helping to fight the COVID-19 pandemic, as well, as we highlighted in the articles listed below:
- An AI program has shown it's possible for chest x-rays to detect unsuspected coronary artery diseases.
- An algorithm could help prevent missed appointments that impact patient care and result in a significant revenue shortfall for radiology departments.
- AI can be used to identify forgotten inferior vena cava filters on radiography exams, according to University of California, San Francisco researchers.
Dual-energy x-ray absorptiometry (DEXA) showed its versatility in measuring bone mineral density in both younger and older patients, as described in the following reports:
- DEXA scans showed boys have lower bone density than girls in a group of Thai teenagers with diabetes.
- Older adults living closer to city green space in Hong Kong unexpectedly showed lower bone density levels on DEXA in a study by environmental researchers.
In addition, while x-ray imaging may be the oldest modality in radiology, researchers are still finding ways to improve it, as shown by the coverage below:
- A simple technique that provides three-point support for scoliosis patients during slot-scanning digital radiography can help evaluate them prior to spinal fusion surgery.
- U.S. National Institutes of Health researchers have developed a small, 3D-printable device for portable chest x-ray systems that improves estimates of head-of-bed angle.
Finally, given the above, it may be hard to imagine that x-ray may be vanishing from urgent care centers, yet that is the perspective of one national expert in urgent care and occupational medicine strategy.
