Abstract
En 中文
• Fixed post-trigger delay does not account for individual patient characteristics. • Individualized post-trigger delay improves objective image quality. • Subjective image quality improves for pancreatic head, body and duct. • Individualized post-trigger delay enhances pancreatic CT image quality.
