January 19, 2009 – Researchers use magnetic resonance imaging (MRI) to show for the first time bleeding inside the heart after people have suffered a heart attack, in a study published in the journal Radiology.
The study was partly by the British Heart Foundation (BHF). Commenting on the significance of the study, Professor Peter Weissberg, medical director at the BHF noted: “For centuries we have relied on pathologists undertaking post mortems to tell us what has happened inside damaged tissues. The power of magnetic resonance imaging is that it can look inside organs of living patients without the need for an operation. We are now at the start of the process of understanding what this information is telling us.”
