Abstract: The aim of the study was to determine the added value of stroke protocol MRI following negative initial CT brain in the acute stroke setting. A retrospective study was performed over a 6 month period in a tertiary referral stroke centre. Patients were selected from the stroke and radiology databases. Inclusion criteria: clinical stroke syndrome, negative initial CT with subsequent MRI study with diffusion weighted sequences. Ninety two patients were reviewed and 73 (M:F of 39:34, mean age 62.1 ± 14.0 years) met the inclusion criteria. Twenty MRI studies (27.4%) were positive for acute/subacute ischaemia in the setting of a normal initial CT. The average time interval between initial CT and MRI brain imaging was 4.7 ± 2.6 days. Whilst CT continues to be the first line imaging investigation for acute stroke, MRI has substantial added value following negative initial CT in the diagnosis of stroke.
