Objective:

To determine whether patient sex significantly influences different enhancements of iodinated contrast using identical administration protocols and to identify parameters for individualized, sex-specific CM dosing, emphasizing the importance of this approach for patient safety.

Key Findings:
  • Women are more likely to experience adverse effects from CM than men, as determined through comparative analysis.
  • The volume of CM injected is often standardized based on body weight, potentially leading to overdosing in women.
  • Individualized CM dosing based on patient characteristics may reduce risks and improve imaging outcomes.
Interpretation:

The study highlights the need for sex-specific considerations in CM dosing protocols to minimize risks associated with contrast-enhanced imaging, particularly for women, and suggests that implementing these changes could enhance patient safety.

Limitations:
  • Single-center study may limit generalizability.
  • Retrospective design may introduce biases in data collection and analysis; future studies should consider multi-center designs.
Conclusion:

There is a critical need to revisit standardized CM protocols to ensure safe and effective imaging practices, particularly for women, to avoid potential overdosing and associated risks, which could significantly impact patient outcomes.
