About this trial
The aim of this study is to investigate the association between intraplaque hemorrhage (IPH) detected by non-contrast magnetic resonance imaging (MRI) of the carotid artery in routine clinical practice and ipsilateral acute ischemic events. The investigators' overarching aim is to determine whether this sequence aids the diagnostic work-up of stroke patients.
For this purpose, the investigators set up a prospective single-center longitudinal observational study with one year follow-up. In addition, this study will analyze retrospectively obtained data collected through clinical routine.
Eligibility criteria
This trial does not accept healthy volunteersQualifiers
Patients with acute ischemic stroke
Availability of non-contrast carotid MRI scans obtained through routine diagnostic work-up
Disqualifiers
Infarct in the posterior circulation or bilateral ischemic infarcts
Time between symptom onset and non-contrast carotid MRI > 10 days
Prior stenting of a carotid artery or carotid endarterectomy
Age < 18 years
Trial population
Patients with acute ischemic stroke, who received non-contrast carotid MRI for routine diagnostic work-up, will be asked whether they are willing to participate in a prospective, longitudinal study with telephone follow-up to assess recurrent ischemic stroke or TIA. Patients who are unable to provide informed consent for themselves, children and adolescents will not be recruited. Detailed eligibility criteria for the prospective longitudinal study are provided above. In addition, this study will analyse retrospectively obtained data collected through clinical routine: These analyses will be done on all patients who received non-contrast carotid MRI for routine diagnostic work-up over the last years. This approach allows to estimate the prevalence of IPH in an unselected patient population.

Trial groups
Trial outcomes
Primary outcomes
intraplaque hemorrhage (IPH)
presence of IPH as detected on routine non-contrast MRI
Secondary outcomes
recurrent ischemic stroke or TIA
recurrent ischemic stroke or transient ischemic attack (TIA)
Plaque-RADS
scoring plaque vulnerability according to the Plaque-RADS (Reporting and Data System) classification (score \[1-4\] with higher scores meaning higher plaque vulnerability) with all data available from clinical routine
Barthel Scale
activities of daily living, assessed using the Barthel Scale (score \[0-100\] with lower scores meaning lower independence in activities of daily living)
modified Rankin Scale (mRS)
modified Rankin Scale (mRS) as a functional global outcome scale measuring the level of disability after stroke (score \[0-6\] with higher scores meaning a worse outcome)
