“…Plenty of research has been conducted on basic concepts and development of AE. (Lajoie & Gube, 2018;Mylopoulos et al, 2018;Pusic et al, 2018;Quirk & Chumley, 2018) (Lajoie, Gube, Lajoie, &Gube, 2018), (Mylopoulos et al, 2018), (Pusic et al, 2018), (Quirk, Chumley, Quirk, & Chumley, 2018), (Kellman&Krasne, 2018), however, a significant proportion of the published literature measuring AE comes from nonmedical fields (Ferguson et al, 2018;Fisher & Peterson, 2001;Martin, Rivale, & Diller, 2007). The goal of this study is to use a validated instrument for measuring the AE of radiology residents who require excellence for dealing with routine and non-routine tasks encompassing a plethora of modalities such as ultrasound, computed tomography, magnetic resonance imaging, fluoroscopy, guided interventions, etc.…”
