  1. PRSS and ULD CT-Pure IR images were compared using a binary scale (1, yes; 2, no) for the included parameters. Contingency squares were generated for each variable, and Fisher’s exact test was performed. A p-value < 0.05 was considered statistically significant
  2. *There were no shunt-related complications in this study
