EBCT vs MDCT

• EBCT has far superior temporal resolution, but
  limited spatial resolution along z axis.
• MDCT has lower temporal resolution, but superior
  spatial resolution.
• Cost of EBCT gtgt Cost of MDCT.
• Reproducibility in current MDCT systems better
  than EBCT.
• EBCT considered Gold Standard for Cardiac
  function, while MDCT has not proven itself over
  long duration.
