Comparison of Magnetic Resonance Techniques for the Measurement of Cerebral Blood Perfusion

Plain-language summary
In this project, we aim at implementing a te-ASL sequence and to compare it to two reference ASL sequences with a fixed PLD on healthy individuals. On the one hand, the te-ASL sequence will be compared against a 3D pCASL with a PLD of 1800 ms, as the current reference according the Consensus of the ISMRM perfusion study group and the European consortium for ASL in dementia. On the other, as the implemented te-ASL sequence will have a 2D readout, it will also be compared to a 2D pCASL ASL sequence with the same PLD, in order to be able to disentangle differences due to the dynamic PLD scheme from those arising from the different read-out schemes.

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
