a
Dual source cardiac reconstruction with 83 ms temporal resolution (¼ of a rotation), from which the high spatial frequency information was obtained, and a dual source full scan reconstruction with 248 ms temporal resolution (¾ of a rotation), from which the low spatial frequency information was obtained.
