“…An X-ray detector unit (scintillator array) is fixed on the other end of the C-arm. The spatial resolution can be selected from 1.04 up to 5.0 line pairs/mm [13]. The C-arm is rotated axially around the patient for scanning at different angles.…”

Purpose: The purpose of this study was to evaluate the diagnostic accuracy of full-body linear X-ray scanning (LS) in multiple trauma patients in comparison to 128-multislice computed tomography (MSCT). Materials and Methods: 106 multiple trauma patients (female: 33; male: 73) were retrospectively included in this study. All patients underwent LS of the whole body, including extremities, and MSCT covering the neck, thorax, abdomen, and pelvis. The diagnostic accuracy of LS for the detection of fractures of the truncal skeleton and pneumothoraces was evaluated in comparison to MSCT by two observers in consensus. Extremity fractures detected by LS were documented. Results: The overall sensitivity of LS was 49.2?%, the specificity was 93.3?%, the positive predictive value was 91?%, and the negative predictive value was 57.5?%. The overall sensitivity for vertebral fractures was 16.7?%, and the specificity was 100?%. The sensitivity was 48.7?% and the specificity 98.2?% for all other fractures. Pneumothoraces were detected in 12 patients by CT, but not by LS.?40 extremity fractures were detected by LS, of which 4 fractures were dislocated, and 2 were fully covered by MSCT. Conclusion: The diagnostic accuracy of LS is limited in the evaluation of acute trauma of the truncal skeleton. LS allows fast whole-body X-ray imaging, and may be valuable for detecting extremity fractures in trauma patients in addition to MSCT. Key Points: ??The overall sensitivity of LS for truncal skeleton injuries in multiple-trauma patients was

“…Our study has the following limitations: Retrospectively, we were not able to recover the effective dose of the LS scans. The entrance dose for full-body anterior/posterior is 0.2 mGy and full spine lateral is 0.75 mGy [13]. Wedegärtner et al [26] analyzed the effective dose applied to multiple trauma patients.…”

A pilot study evaluating erect chest imaging in children, using the Lodox Statscan digital X-ray machine

Background. Chest radiography accounts for a significant proportion of ionising radiation in children. The radiation dose of radiographs performed on the Lodox Statscan system has been shown to be lower than that of a computed radiography (CR) system. The role of the Lodox Statscan (subsequently referred to as the Statscan) in routine erect chest radiography in children has not been evaluated. Objective. To evaluate the image quality and diagnostic accuracy of erect paediatric chest radiographs obtained with the Statscan and to compare these with conventional erect chest images obtained with a CR system. Materials and methods. Thirty-three children with suspected chest pathology were enrolled randomly over a period of 3 months. Erect chest radiographs were obtained with the Statscan and a Shimadzu R-20J X-ray machine coupled with a Fuji FCR 5000 CR system. Image quality and diagnostic accuracy and diagnostic capability of the two modalities were evaluated and compared. Results. The erect Statscan allowed superior visualisation of the 3 major airways. Statscan images, however, demonstrated exposure and movement artifacts, with hemidiaphragms and ribs most prone to movement. Bronchovascular clarity was also considered unsatisfactory on Statscan images. Conclusion. The Statscan has limitations in erect chest radiography in terms of movement artefacts, exposure fluctuations, and poor definition of lung markings. Despite this, the Statscan allows better visualisation of the major airways, equivalent to a 'high kV' film, at a fraction of the radiation dose, which supports the finding of an earlier study evaluating Statscan images in trauma cases, where the images were taken supine. The Statscan has great potential in assisting in the diagnosis of childhood tuberculosis where airway narrowing occurs as a result of nodal compression.

“…This comes as no surprise. Irving et al 11 examined a modern linear slit scanner and found the effective dose for a head anteroposterior scan to be a third of the typical conventional radiography dose. For the same scanner, Maree et al 12 found significantly lower doses for all pediatric examinations compared with conventional radiography.…”

BACKGROUND AND PURPOSE:For CT scan planning, scan projection radiographs (SPR) are used. Tube tension and current for head SPR can be reduced to a minimum because of the small head diameter and because only high-contrast structures need to be visualized for planning. The goal of this study was to investigate SPR of the head in respect to effective doses, the influence of dose-reduction measures, and comparison with conventional x-ray.
