Advice table for the use of CT and MR in the diagnosis and management of neurological complications

Advice for the use of CT and MR in the diagnosis and management of neurological complications	Strength of advice	Imaging modality	CT specifications	MR specifications
(1) Emergent brain imaging is advised in all patients with new neurological symptoms compatible with cerebral ischaemia after left cardiac chamber ablation before initiation of any specific therapy		CT or MRI
(2) In patients who are potential candidates for treatment with intravenous fibrinolysis, a non-contrast CT or MRI is advised to exclude intracranial haemorrhage		CT	Cerebral non-contrast CT
(3) In patients who are potential candidates for treatment with mechanical thrombectomy, non-invasive imaging of the intracranial arteries is advised during the initial imaging evaluation		CT or MR	Angiography	Angiography
(4) In patients presenting with new neurological symptoms within 6 weeks of the ablation, emergent brain imaging is advised, followed in the case of pathological findings by a chest CT to evaluate for atrio-oesophageal fistula		CT or MR

CT, computed tomography; MR, magnetic resonance.
