In ICU-patients, diaphragm weakness is associated with prolonged ICU-stay, difficult weaning and increased mortality. Our research group recently found evidence for fibrosis and expression of genes involved in fibrosis as well as viral infiltration of the SARS-CoV-2 virus in diaphragm biopsies from COVID-19 ICU patients. This finding suggests a unique manifestation of diaphragm injury in COVID-19 patients after mechanical ventilation. However, it remains unclear what the exact nature and location of diaphragm injury is.\n\nAdditionally, it is largely unknown whether this injury affects the movement of the diaphragm, but this might have important clinical implications. Therefore, we aim at visualizing the tissue characteristics and movement of the diaphragm in COVID-19 patients who recently received long-term mechanical ventilation, other ICU patients and healthy controls, using magnetic resonance imaging (MRI). MRI of the diaphragm was already shown feasible in previous research from our group (article currently under review).\n\nNew insights in the characteristics of diaphragm weakness and injury in COVID-19 patients and control ICU-patients will contribute to strategies to prevent it and monitor the diaphragm of patients under mechanical ventilation, which can contribute to better patient outcomes.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'minimumAge': '18 Years', 'samplingMethod': 'NON_PROBABILITY_SAMPLE', 'studyPopulation': 'Patients that were recently (\\<= 7 days ago) discharged from the ICU and received mechanical ventilation form the study population with a specific sub group of COVID-19 patients.
