A human heartbeat has been imaged by a magnetic resonance scanner for the first time. Greg Hundley and colleagues at the Wake Forest University Baptist Medical Center in North Carolina have developed a software program that can analyse a magnetic resonance scanner within seconds, rather than the five minutes needed at present. This allows doctors to look at images of a beating heart in close to real-time. The team hopes to use the technique to look for abnormal pumping motions that could indicate blocked arteries (Circulation 100 1697).
