Multi-Scale Temporal Imaging: From Micro- and Meso- to Macro-scale-time Nuclear Medicine

Area of Science:

• Medical imaging analysis
• Temporal dynamics in healthcare

Background:

• Time is crucial for understanding change in medical imaging.
• Three temporal scales exist: microtime (single session), mesotime (short-term sessions), and macrotime (long-term scans).
• Current research and clinical practice prioritize microtime and mesotime.

Purpose of the Study:

• To highlight the underutilized macrotime scale in medical imaging.
• To emphasize the importance of long-term temporal analysis for medical insights.

Main Methods:

• Conceptual analysis of temporal scales in medical imaging.
• Review of current practices and research focus.

Main Results:

• Medical imaging research predominantly focuses on microtime and mesotime.
• Macrotime, encompassing months to years, receives less attention.
• This imbalance limits comprehensive understanding of long-term disease progression and treatment effects.

Conclusions:

• The macrotime scale in medical imaging is critically under-explored.
• Future research should incorporate macrotime analysis for deeper insights into chronic conditions and treatment efficacy over extended periods.
