Cerebral venous sinus thrombosis cases detected in on-call CT venographies in Sweden, 2019-2022.

No well-established criteria exist for assessing the risk of cerebral venous sinus thrombosis (CVST). Here, we sought to gain an understanding of CVST cases and associated risk factors, based on the rates of emergency CT venographies (CTVs) performed after hours. Furthermore, we aimed to assess possible correlations between CVST rates and COVID-19, including at the start of the COVID-19 vaccination campaign.

Quality Assurance of a Cross-Border and Sub-Specialized Teleradiology Service.

Background: The current literature discusses aspects of quality assurance (QA) and sub-specialization. However, the challenges of these topics in a teleradiology network have been less explored. In a project report, we aimed to review the development and enforcement of sub-specialized radiology at Telemedicine Clinic (TMC), one of the largest teleradiology providers in Europe, and to describe each step of its QA.

Impact of COVID-19 on the incidence of CT-diagnosed appendicitis and its complications in the UK and Sweden.

Aim: To compare the number of appendicitis cases and its complications, during the first months of the COVID-19 pandemic in Sweden and the UK and the corresponding time period in 2019.

Method: Reports of emergency abdominopelvic CT performed at 56 Swedish hospitals and 38 British hospitals between April and July 2020 and a corresponding control cohort from 2019 were reviewed. Two radiologists and two surgeons blinded to the date of cohorts analyzed all reports for diagnosis of appendicitis, perforation, and abscess.
