SMRT Educational Seminars
Diffusion-Weighted MR Imaging of the Pediatric Brain
Volume 6, Number 4
The SMRT Educational Seminars (Volume 6, Number 4), has been approved for 1.5 Category A Continuing Educational credits.

Read the SMRT Educational Seminars (Volume 6, Number 4), "Diffusion-Weighted MR Imaging of the Pediatric Brain" and complete the quiz and official Answer Form at the back of the article. To receive credit the quiz must be completed with a score of 75% or better. Completion of all questions with a passing score will earn a total of 1.5 category A Continuing Education credits.
SMRT members should send the completed Answer Form to the SMRT Education Department for scoring. The certificate will state the CE reference number and awarded CE credits. Members receiving a score less than 75% will be notified and given the option of taking the quiz an additional two times. Members should retain their CE Certificate for their Continuing Education registry requirements.
Educational Objectives
Changes in Brain Water Diffusion During the First Year of Life
  • Define the terminology and concepts pertaining to DWI;
  • Identify the type of subjects and establish the imaging parameters and analytical methods used in the study;
  • Demonstrate the relationship of ADC values to subject age, as well as correlate variations in ADC values among different regions in the brain;
  • Emphasize the importance of age specific ADC values in the interpretation of pediatric DW images;
  • Account for factors contributing to the decline of ADC values with age;
  • Compare ADC values of different regions of the brain to established patterns pf myelination during the first year of life.

Diffusion-Weighted MR Imaging in the Brain in Children: Findings in the Normal Brain and in the Brain with White Matter Diseases

  • Review of disease processes which effect ADC values in both adults and children;
  • Describe the imaging parameters specific to DWI including the value of anistropic versus isotropic diffusion processes, and the utility of diffusion-sensitizing gradients;
  • Examine the findings of DWI in pediatric brains;
  • Identify and differentiate the various study results of pediatric DWI;
  • Summarize the ADC values found in cases where demyelination processed are not present and correlate ADC values to specific demyelination patterns present in certain diseases.
