Quick Answer: Multiregional clinical trial imaging guidelines are standardized protocols and requirements established by regulatory bodies like the FDA and EMA for conducting imaging-based clinical trials across multiple countries. These guidelines ensure consistent image acquisition, quality control, and data interpretation while maintaining regulatory compliance across different regions.
Latest Statistics and Impact (2024)
According to recent industry data:
- Only 20% of clinical trials meet their original deadlines, with imaging protocol variations being a significant factor
- Global multiregional clinical trials (MRCTs) have increased by 80% since 2019
- Standardized imaging protocols can reduce data variability by up to 40%
- The average MRCT spans 4-6 countries and requires coordination of 12-15 imaging centers
