Comparison 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 ...

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 کاملConventional vs Computed Radiography : Evaluation of Myelography 165
Digital imaging is becoming widely used in diagnostic radiology, and digital subtraction angiography (DSA) is now generally accepted [1-3]. Several studies have evaluated digital imaging using a computed radiography system for chest examinations [4-10] and for excretory urography [11] . This prospective study uses receiver operating curve analysis [12 , 13] to compare the diagnostic accuracy of...

CE Email comments/questions to [email protected], fax 800-556-3288, or log on to www.VetLearn.com Computed radiography (CR) is a digital imaging technology and digital x-ray image management system that has been used in human and veterinary medicine since the 1980s. CR helps eliminate many of the disadvantages of traditional radiography. A storage phosphor plate collects the pattern of x...
متن کاملColor radiography in lung nodule detection and characterization: comparison with conventional gray scale radiography
BACKGROUND To compare the capability of lung nodule detection and characterization between dual-energy radiography with color-representation (DCR) and conventional gray scale chest radiography (GSR). METHODS A total of 130 paired chest radiographs (DCR and GSR) obtained from 65 patients (14 with normal scans and 51 with pulmonary nodules) were evaluated. After analysis, 45 non-calcified and 2...
