Patient characteristics and adverse events during portable brain MRI scan

	Age (years)	Sex	BMI	ECMO indication	Cannulation strategy	Neurologic symptoms	MRI time (min)	HCT finding	MRI finding	ABI management	Adverse events*
1	47	Male	30.5	COVID-19 ARDS	Fem-IJ (VV-ECMO)	Coma under sedation	40	Acute left occipital ischemic stroke with hemorrhagic conversion	Acute left occipital ischemic stroke	Anticoagulation held and restarted with serial imaging studies	One self-limited ECMO suction event
2	45	Male	32.5	COVID-19 ARDS	Fem-IJ (VV-ECMO)	Coma under sedation	43	No acute findings	None	Not applicable	None
3	55	Female	27.1	Cardiogenic shock with PE	Fem–Fem (VA-ECMO)	Coma under sedation	34	No acute findings	Acute right basal ganglia ischemic infarct	Anticoagulation held and restarted with serial imaging studies	Frequent ECMO suction events, received intravenous fluids; improved with repositioning patient*

ARDS: Acute respiratory distress syndrome; VV: venovenous; Fem-IJ: femoral–internal jugular; VA: venoarterial; Fem-Fem: femoral–femoral; ECMO: extracorporeal membrane oxygenation; PE: pulmonary embolism; ABI: acute brain injury. *It was noted that the patients torso was positioned in slight extension, bed and MRI were flattened to remove extension with resolution in suction events. *There were no serious adverse events in all patients
