COVID-19 and vaccination impact on radiology departments provided by Dose Archiving and Communication System.

ABSTRACT:

Objectives

To study the impact of COVID-19 on chest CT practice during the different waves using Dose Archiving and Communication System (DACS).

Methods

Retrospective study including data from 86,136 chest CT acquisitions from 27 radiology centers (15 private; 12 public) between January 1, 2020, and October 13, 2021, using a centralized DACS. Daily chest CT activity and dosimetry information such as dose length product (DLP), computed tomography dose index (CTDI), and acquisition parameters were collected. Pandemic indicators (daily tests performed, incidence, and hospital admissions) and vaccination rates were collected from a governmental open-data platform.
