Heart scan surprises: CT reveals many non-heart problems, too
... who get their hearts scanned with a high-speed CT scanner
may get a shocking surprise: a diagnosis of a serious problem that has nothing to do with their heart. New research from the University of Michigan shows that 43 of 98 patients who had a CT heart scan to look for clogged arteries were also found to h...
