Background And Purpose: So-called contrast-induced encephalopathy (CIE) is a rare but worrying condition occurring after cerebral angiography or neuroendovascular interventions using iodine contrast media. This study aimed to compare cerebral iodine concentrations in patients suspected of having CIE after endovascular procedures to those in matched controls.
Methods: This is a retrospective monocentric study of 25 suspected CIE patients in a tertiary care teaching hospital diagnosed from June 2017 to February 2024.
Article Synopsis
- The study investigates changes in the structure of brain arteriovenous malformations (AVMs) following incomplete endovascular embolization, focusing on the modifications that occur over time.
- A retrospective analysis of 57 patients revealed a 40% rate of angioarchitectural modifications, with 28% showing regression features and 18.3% exhibiting progression.
- The research identified that longer intervals between embolization and follow-up correlated with nidal volume growth, highlighting the need for careful monitoring post-treatment.
Objectives: Whether COVID-19 leads to long-term pulmonary sequelae or not remains unknown. The aim of this study was to assess the prevalence of persisting radiological pulmonary fibrotic lesions in patients hospitalized for COVID-19.
Materials And Methods: We conducted a prospective single-center study among patients hospitalized for COVID-19 between March and May 2020.
Article Synopsis
- The balloon pressure technique (BPT) utilizes a dual lumen balloon for injecting liquid embolic agents while inflated, providing an alternative to traditional pressure cooker methods for treating brain arteriovenous malformations (bAVMs).
- A study reviewed 19 patients treated between July 2020 and July 2021 using the Scepter Mini balloon, evaluating complications and occlusion rates following the procedure.
- Results showed that while some patients experienced complications like ischemic strokes and hemorrhages, the BPT was generally feasible and achieved high rates of bAVM occlusion, indicating its potential effectiveness and safety for embolization.
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.
