About this study

Official title: Optimization of Non-contrast Enhanced 1.5 Tesla and 3 Tesla Cardiac Magnetic Resonance Imaging Techniques and Acquisition of Normal Values

One of the main problems in cardiac magnetic resonance (MR) investigations is the strong dependence of the achieved image quality on optimal settings of sequence parameters and anatomical and physiological situations and it is well known that the diagnostic impact of cardiac MR investigations crucially depends on the adaption of imaging protocols to patients' state and ability to cooperate.

The aim of the present study is the evaluation and optimization of various 1.5 Tesla and 3 Tesla cardiac MR investigation protocols without application of contrast agent as well as the acquisition of normal values for new cardiac MR images techniques:

  • normal myocardial morphology: T1-, T2- and T2*-weighted imaging and acquisition of normal values of magnetic relaxation times (sequence- and protocol dependent),
  • normal cardiac function: systolic and diastolic function (sequence- and protocol dependent),
  • cardiac anatomy and coronary artery imaging: feasibility to evaluate length, diameter and blood flow (sequence- and protocol dependent),
  • normal blood flow topologies in the heart and the surrounding great vessels: 2D- and 3D blood flow imaging and evaluation techniques (sequence- and protocol dependent).

Questions about this trial

What is this clinical trial studying?

An observational study of Healthy, run by Medical University of Graz at 1 site in Austria.

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 2 inclusion and 3 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: looking for participants now, as of the sponsor's last update on 12 Feb 2025. 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 Austria. 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?

This study is still under way. Results are not available in the source record yet.

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

Contact Ursula Reiter, PhD (+43-316-385 ext. 83347, ursula.reiter@klinikum-graz.at), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

cardiac volumes (time frame: up to 1 week). The study lists 8 primary outcomes in all. 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 NCT01728597, which also lists 5 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 12 Feb 2025.
