Data management practices of cone beam computed tomography volumes: An exploratory user survey

Abstract

Objective: The aim of this study was to query cone beam computed tomography (CBCT) users about their storage and transfer practices to identify trends in the handling of CBCT data in dentistry. Study Design: A computer-based survey was distributed to 2 CBCT user groups. The survey consisted of 18 questions on settings for data capture, data storage, archiving strategies, bit depth/compression, monitoring user access to patient information, and dissemination to end users. All information was anonymously collected. Descriptive data and frequency patterns were collected and discussed. Results: A total of 68 surveys were returned, with 56 fully completed. Results reflected a low consensus about usage and management of radiographic data sets. Some preferential usage patterns, however, were noted along with the following trends: (1) 53% of respondents utilized Digital Imaging and Communications in Medicine volumetric data sets for initial storage. (2) 46% of respondents saved data in raw or native file formats. (3) 60% of storage sites were in onsite servers. (4) 35% of volumes saved were in a “Zip” compression format. (5) 37% of respondents used a picture archiving and communication system for storage. Conclusions: The absence of consensus on postcapture management of volumetric data sets indicates that a dentistry-wide data management standard would benefit patient care while mitigating information technology storage issues.
