Reveal 35C images from KA Imaging shown to increase visibility of lung lesions

WATERLOO, Ontario–(BUSINESS WIRE)–KA Imaging, a company that develops innovative X-ray imaging solutions, announced the first results of a study examining the diagnostic value of single exposure dual energy subtraction radiography in the detection of lung lesions.

In the study, a radiologist unaware of standard CT scan results was first asked to identify abnormalities in conventional X-ray. The same task was given right after that, with completed single-exposure dual-energy images. Quoting directly from the poster, “Visibility of lesions was reported to have increased in 45% of cases when additional dual-energy images were included.1.” The results were validated by CT.

“Lung cancer is the leading cause of cancer death; unfortunately, statistics show that it is rarely detected early,” says Karim S. Karim, CTO of KA Imaging. “The promising results of this trial show that spectral images can play an important role in early detection for better outcomes,” said Amol Karnick, President and CEO.

The study will be presented in an e-poster at this year’s European Congress of Radiology (ECR). In addition to the e-poster at the scientific congress, KA Imaging is part of the technical exhibition at Expo X4, booth 406.

ECR is one of the largest medical meetings in Europe and the second largest radiological meeting in the world. ECR participants span all areas of radiology, including radiology professionals, radiographers, physicists, industry representatives, and medical and consumer press journalists.

Recently, KA Imaging announced that its patented single-exposure dual-energy technology is now branded SpectralDR™. The SpectralDR™ enables dual-energy subtraction, providing bone and tissue differentiation with a single standard X-ray exposure. It acquires three images simultaneously (DR, dual-energy X-ray images of bones and soft tissues). The technology mimics the workflow, dose, and techniques of state-of-the-art DR mobile X-ray detectors.
