Virtual reading room for diagnostic radiology

Abstract

Rationale and ObjectiveTo assess the perceptions of radiology staff regarding the role of virtual reality technology in diagnostic radiology after using a virtual reality (VR) headset MethodsParticipants completed a pre-study questionnaire assessing their familiarity with VR technology and its potential role in radiology. Using a VR headset, participants entered a simulated reading room (SieVRt, Luxsonic Technologies) with three large virtual monitors. They were able to view plain radiographs, ultrasound, CT, and MRI images and pull up and compare multiple images simultaneously. They then completed a post-study questionnaire to re-assess their perception about the role of VR technology for diagnostic radiology. ResultsFifteen participants were enrolled, with 33.3 % attendings, 40 % fellows, and 26.7 % residents. Pre-study, 60 % reported they were “not familiar” with VR technology and 66.7 % had never used it. On a 1 to 5 scale, the median perceived likelihood of VR having a role in radiology significantly increased from 3 (IQR 2–3) pre-study to 4 (IQR 4–4) post-study; p = 0.014. Image contrast and resolution were adequate according to most participants, with 53.3 % strongly agreeing and 33.3 % agreeing. The headset was comfortable for 73.3 % and did not induce nausea in any participant. Confidence in VR technology improved after using the headset for 80 %. According to 80 %, future VR technology could replace a PACS workstation. DiscussionRadiologists’ perception regarding the role of virtual reality in diagnostic interpretation improves after a hands-on trial of the technology, and VR has the potential to replace a traditional workstation in certain situations.
