About this study

Official title: 3T Stroke MRT for Examining Mismatch in the CSB of the Charité Universitätsmedizin Berlin (3Tesla in 1000+)

The purpose of this study is to compare clinical and economic parameters of stroke patients who have received acute MRI imaging (test group) to patients who have received routine CT imaging (control group) in the clinical setting of acute stroke.

Read the detailed description

The primary objective:

  • Prospective validation of infarct development in ischemic stroke and transitory ischemic attacks on the basis of all patients given a preliminary diagnosis of stroke or TIA in the emergency ward of the Benjamin Franklin Campus of Charité-Universitätsmedizin Berlin.

Secondary objectives:

  • Determination of the spontaneous reperfusion rate in patients with an initial mismatch in the correlation between the time from onset of symptoms to the time of first imaging and NIHSS score severity
  • Characterization of metabolic changes in ischemic tissue in cases of minor subcortical infarct using high resolution diffusion weighted MRI (DWI) and perfusion MRI with 2nd pass corrected CBF cards
  • Proof of the principle that stroke MRI can improve patient care / shorten the period in which patients are bedridden
  • Measurement of the diffusion tensor in acute ischemic stroke (Hamburg DTI study)
  • Proof of structural damage and investigation of pathogenesis in patients suffering from clinical transitory ischemic attacks (TIA)
  • Investigation of the correlation of clinical symptoms and lesion site as well as of changes in cortical plasticity in patients with solitary thalamus infarct
  • Brain plasticity and motor learning in cases of a purely cortical infarct
  • Characterization of gender specific damage patterns in stroke
  • Morphologic and pathophysiological typing of the cryptic and cardial embolic infarct in correlation to incidence of arrhythmia
  • Characterization of localization and morphology of infarcts in patients presenting in the emergency ward with central vestibular nerve syndrome / recording frequency of cerebral sessions in patients presenting with a primary diagnosis of central vestibular nerve lesion
  • Clinical characterization of cerebellar and brain stem infarcts which are accompanied by vertigo symptoms and their correlation to infarct location

Questions about this trial

What is this clinical trial studying?

An observational study of Acute Stroke and Transient Ischemic Attack, run by Charite University, Berlin, Germany at 1 site in Germany.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 1 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 24 Jun 2014. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Germany. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

change of infarct size between baseline and day 6 (time frame: day 6). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00715533, which also lists 15 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 24 Jun 2014; AzTrials last refreshed its copy on 6 Nov 2026.
