Application-specific nuclear medicalin vivoimaging devices.

Area of Science:

• Nuclear medicine
• Medical imaging technology
• Biomedical engineering

Background:

• Current whole-body nuclear imaging systems (gamma cameras, SPECT, PET) are optimized for general body assessment.
• These systems have limitations in sensitivity and spatial resolution for detailed organ imaging.
• Application-specific nuclear imaging devices have been developed to address these limitations.

Purpose of the Study:

• To review application-specific nuclear imaging devices developed in the 21st century.
• To focus on devices for brain, cardiac, breast, and prostate imaging.
• To discuss challenges and prospects for clinical translation.

Main Methods:

• Review of scientific literature on application-specific nuclear imaging devices from the past two decades.
• Analysis of technical characteristics, advantages, and limitations.
• Discussion of clinical integration and translation challenges.

Main Results:

• Application-specific devices demonstrate superior detection sensitivity and spatial resolution for organ imaging.
• Integration with anatomical imaging modalities enhances their utility.
• Several promising devices have emerged for niche applications.

Conclusions:

• Application-specific nuclear imaging devices show significant promise for specialized organ imaging.
• Overcoming design limitations and gathering robust clinical data are crucial for routine adoption.
• Sustained research and development are necessary to define their full clinical value.
