AB  - This paper discusses the merits and weaknesses of the standard terms that have 
      been developed to quantify CT dose: CT dose indices (CTDI), dose length product 
      (DLP) and effective dose. The difference between the measured CTDIvol and the 
      CTDIvol displayed on the CT scanner illustrates a clinical dilemma. Displayed 
      CTDIvol represents the radiation dose delivered to a plastic phantom, which is 
      significantly different from the dose delivered to the patient, depending on the 
      size of the patient. Although effective dose is simple to calculate for an 
      individual patient, it was never intended for this purpose. The need for a 
      simple, appropriate method to estimate pediatric patient doses led to the 
      development of the size-specific dose estimate (SSDE), the newest CT dose index. 
      Here I compare SSDE and its merits to the use of effective dose to estimate 
      patient dose. The discussion concludes with a few sample calculations and basic 
      clinical applications of SSDE to better quantify pediatric patient dose from CT 
      scans.
