“…We have previously discussed the potential for variable recognition of anatomical structures on ultrasound, even by experienced regional anesthesiologists (Bowness, Turnbull, Taylor, Halcrow, Chisholm, et al, 2019; Bowness, Turnbull, Taylor, Halcrow, Raju, et al, 2019). Based on this information, we presented the case for the use of assistive artificial intelligence (AI) technology to facilitate the recognition of anatomical structures in UGRA (Bowness et al, 2020). This concept has also been proposed by other groups, both for UGRA (Alkhatib et al, 2019; Huang et al, 2019) and central neuraxial blockade (spinal and epidural) (Oh et al, 2019; Smistad et al, 2018; Tran & Rohling, 2010).…”
