In the most common form of heart failure, the heart muscle does not relax properly during the resting phase of the heartbeat. This condition is also known as diastolic heart failure and primarily affects women. Early treatment can slow down or potentially prevent heart failure. MRI scans can be helpful in this regard. However, the drawbacks of MRI include the lengthy duration and hence the cost of the examination, as well as the requirement for the patient to receive an injection of a contrast agent. In this project, the research team is constructing a new MRI antenna to capture images of the heart much more quickly. Additionally, the team will develop new MRI methods that allow doctors to examine the heart without the need for a contrast injection. This makes it possible to identify the early stages of diastolic heart failure sooner.
