Hello!
The challenge proposal mentions that the images are sourced from a pediatric cohort of infants. Could you please specify the exact age range of the subjects included in the challenge? Thanks for the clarification.

Thanks for your question!
**TASK 1:** For the demographic information we have available, the age range of subjects in this task spans from **1 to 510 days with a mean age of 232 days and standard deviation of 150 days**. _For this task, age information is unavailable for about 10% of the 252 subjects._
**TASK 2:** Age metadata accompanies all scans. Subjects' age ranges are **32 to 510 days, with a mean of 286 days and standard deviation of 143 days.**
