The insanity never stops. It's a good thing MRI is becoming increasingly available, because the more papers like this are published in major journals, the more we're going to be stuck following every possible outcome to it's bitterest end with the strongest microscope we have.
There a lots of problems with using this paper to change practice - of their 9152 patients undergoing CT for trauma, 741 had persistent midline tenderness leading towards MRI. Of those 741, only 174 were enrolled for a variety of reasons. And this study doesn't tell us enough useful information to help distinguish the characteristics of the 78 patients in whom an injury was detected to help us differentiate them from the patients in whom no injury was detected.
But the fact remains, they identified serious injuries on MRI in patients who had negative CTs - and not just obtunded, intubated, polytrauma patients like in the other studies.
Just one more thing to worry about.
