From their discussion there are some caveats:
- mostly white people checked (so if you're Asian, this might not happen)
- MRI has a known bias towards participation of healthy people, as unhealthy people don't like to hear the "news" about their condition
- the study is "cross-sectional", i.e., the MRI is just from one point in time. Having several measurements from the same people over a period of time (in years) would be much, much better.

P.S.: To lift your mood, the first comment in the news-article is hilarious: "now the government obama care will start to penalize people with high blood pressure? absurd, they just need more cash."
