چکیده
Recently, some facilities have utilized the dual-energy subtraction (DES) technique for chest radiography to increase pulmonary lesion detectability. However, availability of is limited certain facilities, in addition other limitations, such as increased noise high-energy images and motion artifacts with one-shot two-shot methods, respectively. The aim this study was develop artificial intelligence-based DES (AI–DES) technology overcome these limitations. Using a trained pix2pix model on clinically acquired radiograph pairs, we successfully converted 130 kV into virtual 60 that closely resemble real images. averaged peak signal-to-noise ratio (PSNR) structural similarity (SSIM) between were 33.8 dB 0.984, We also achieved production soft-tissue- bone-enhanced using weighted image process soft-tissue-enhanced exhibited sufficient bone suppression, particularly within lung fields. Although contained around lower thoracic lumbar spines, superior sharpness characteristics presented. main contribution our development its ability provide selectively enhanced specific tissues only obtained via routine radiography. This suggests potential improve detectability lesions while addressing challenges associated existing technique. further improvements are necessary quality.

ID: 9840 Title: Dual Energy Chest Radiography Dual Energy Chest Radiography Visual detection of pulmonary abnormalities on screen-film radiographs is notoriously unreliable. Digital radiography can improve diagnostic accuracy due to its greater latitude, improved local contrast and more consistent image quality compared to screen-film systems. In addition to facilitating detection by traditiona...
متن کاملComparison of dual energy subtraction chest radiography and traditional chest X-rays in the detection of pulmonary nodules.
BACKGROUND Dual energy subtraction (DES) radiography is a powerful but underutilized technique which aims to improve the diagnostic value of an X-ray by separating soft tissue from bones, producing two different images. Compared to traditional chest X-rays, DES requires exposure to higher doses of radiation but may achieve higher accuracy. The objective of this study was to assess the clinical ...

Evaluation of a commercial cardiac motion phantom for dual‐energy chest radiography
Misregistration due to cardiac motion causes artifacts in two-exposure dual-energy subtraction images, in both the soft-tissue-only image and the bone-only image. Two previous investigations have attempted to avoid misregistration artifacts by using cardiac gating of the first and second exposures. The severity of misregistration was affected by the heart rate, the time interval between the low...
