Perfusion brain CT performed at normal head CT doses
By Eric Barnes
Friday, December 3 | 11:10 a.m.-11:20 a.m. | SST14-05 | Room S403BIn brain perfusion CT, multiple time-resolved images are needed to track the flow of contrast through the brain, leading to higher radiation doses in the range of 300-500 mGy. But researchers from the Mayo Clinic in Rochester, MN, can do it with less radiation -- down to 75 mGy -- using a gradient adaptive bilateral filter noise reduction algorithm.
