Examining Practitioners' Assessments of Perceived Aesthetic and Diagnostic Quality of High kVp–Low mAs Pelvis, Chest, Skull, and Hand Phantom Radiographs

Abstract: This study investigated the usefulness of the dose optimization strategy of increased tube voltage (kVp) and decreased tube current-exposure time product (mAs) (or high kVp-low mAs) by examining practitioners' assessments of perceived aesthetic and diagnostic quality of direct digital radiographs acquired using this strategy. Ninety-one practitioners (radiologists, radiology residents, radiographers, and radiography students) from eight clinical sites in Ontario examined three types of radiographs (''standard'… Show more

“…This agrees with and validates the high kVp technique as a dose saving tool on direct digital radiographic systems. 8,9,[11][12][13][14][15][16][17] There were, however, differences in the amount of dose reduction observed between each projection and region of interest. For AP pelvis projections, increasing the kVp from 75 to 85 saw a 46.9% reduction in the mean DAP value.…”

“…Each image was awarded a score from 0 to 15, based on a visual grading analysis (VGA) rubric, shown in Figure 2, that was derived from the Commission of European Communities Guidelines for Image Quality Criteria for Diagnostic Radiographic Images 26 . These guidelines have been widely used and adapted for image quality assessments in the literature, with a number of the previously mentioned high‐kVp studies adopting these guidelines in some capacity 8,11,12,14‐16 …”
