“…5,15 There is a paucity of literature on the use of VGC analysis for evaluating the image quality of angiographic images. Studies have previously used VGC analysis for extremity computed tomography (CT), [16][17][18] chest, appendicular, and spine radiography, [19][20][21][22][23][24] abdominal CT, [25][26][27] head CT, 28,29 pelvic CT, 30 propagation-based phase-contrast CT, 31 pediatric radiograph, 32 and magnetic resonance imaging (MRI) olfactory bulb volumetry sequences. 33 Fridh et al 10 used angiographic images from lower limb DSA runs to detect infrapopliteal lesions, where the observers were interventional radiologists or vascular surgeons.…”

.PurposeThe aim of our study was to compare the image quality assessments of vascular anatomy between interventional radiographers and interventional radiologists using digital subtraction angiography (DSA) runs acquired during an interventional radiology procedure.ApproachVisual grading characteristics (VGC) analysis was used to assess image quality by comparing two groups of images, where one group consisted of procedures in which radiation dose was optimized (group A, n = 10) and one group where dose optimization was not performed (group B, n = 10). The radiation dose parameters were optimized based on theoretical and empirical evidence to achieve radiation dose reductions during uterine artery embolization procedures. The two observer groups comprised of interventional radiologists (n = 4) and interventional radiographers (n = 4). Each observer rated the image quality of 20 DSA runs using a five-point rating scale.ResultsThe VGC analysis produced an area under the VGC curve (AUCVGC) of 0.55 for interventional radiographers (P = 0.61) and AUCVGC of 0.52 for interventional radiologists (P = 0.83). The optimization of radiation dose parameters demonstrated a reduction in kerma-area product by 35% (P = 0.026, d = 0.5) and reference air kerma (Ka, r) by 43% (P = 0.042, d = 0.5) between group A and group B.ConclusionsVGC analysis indicated that the image quality assessments of interventional radiographers were comparable with interventional radiologists, where a reduction in radiation dose revealed no effect on both observer groups regarding their image quality assessment of vascular anatomy.

“…With the latter in mind we include valuable articles about REF and impact 7 and about evidence-based healthcare. 8 For the use of research in teaching, there is a "Guest Editorial about OPTIMAX 9 and associated with this are four research articles, 10 , 11 , 12 , 13 to illustrate how students can engage in research to learn about the research process and produce outcomes. There is an interesting article outlining how crowd sourcing can help inform curriculum design 14 and a pan-European article offers a perspective on radiographer research into radiation protection and its implementation.…”
