Using MRI scans to measure fluid in lungs during acute heart failure

This trial is testing whether MRI scans can give doctors a more precise measurement of how much fluid builds up in the lungs during acute heart failure (a sudden worsening of the heart's ability to pump blood). Right now, doctors use chest X-rays and physical exams to estimate this fluid, but MRI may be more accurate. The study will compare these measurements at the time you enter the hospital and when you leave, to see how well the MRI readings predict your health over the next 5 years.

Doctors need better ways to measure and understand lung fluid in acute heart failure so they can predict which patients will do well or poorly after leaving the hospital and improve how they manage treatment.
