Clinical Application of Low-Field Magnetic Resonance Imaging in Patients on Extracorporeal Cardiopulmonary Resuscitation

Timely identification of acute brain injury (ABI) patterns in patients with extracorporeal cardiopulmonary resuscitation (ECPR) is essential for prognostic assessment and optimization of clinical management, particularly anticoagulation strategies. This study aimed to evaluate the safety and feasibility of early 0.23-T MRI examination in ECPR patients. The investigators further assessed the image quality of the 0.23-T MRI and investigated the incidence and patterns of ABI, as well as their associations with neurological outcomes. This prospective observational study was conducted in the emergency intensive care unit (EICU) of Beijing Chaoyang Hospital, a high-volume ECPR center. The primary outcome was the feasibility of performing 0.23-T MRI in patients undergoing ECPR, defined as successful completion of the examination without serious adverse events (AEs).
