KA Imaging is touting initial results from a study examining the diagnostic value of single-exposure dual-energy subtraction radiography in lung lesion detection.
In the study, a radiologist blinded to standard-of-care CT results was first asked to identify anomalies in the conventional X-ray. The same task was given right after that, with supplemented single-exposure dual-energy images. Quoting directly from the poster, “lesion visibility reportedly increased in 45% of the cases when supplemental dual-energy images were included.”1 Findings were validated using computed tomography (CT).
“Lung cancer is the leading cause of cancer death; unfortunately, statistics show that it is rarely detected early,” explained Karim S. Karim, chief technology officer of KA Imaging.
“The results from this trial show that spectral images can play an important role in earlier detection for better outcomes,” said Amol Karnick, president and CEO.
Recently, KA Imaging announced that its patented single-exposure dual-energy technology is now branded SpectralDR. The SpectralDR technology enables dual-energy subtraction, providing bone and tissue differentiation with a single standard X-ray exposure. It acquires three images simultaneously (DR, bone and soft tissue dual-energy X-ray images). The technology mimics the workflow, dose and techniques of state-of-the-art mobile DR X-ray detectors.
A spin-off from the University of Waterloo, KA Imaging develops X-ray imaging technologies and systems, providing solutions to the medical, veterinary, and non-destructive test industrial markets.
