Introduction

Translational medicine has emerged as a critical bridge between laboratory research and clinical practice. It aims to accelerate the transition of scientific discoveries into tangible advancements in patient care. One significant development in this field is the integration of preclinical imaging techniques into clinical radiology [1]. This merger offers exciting prospects for enhancing translational medicine by improving our understanding of diseases, treatment strategies, and patient outcomes.

Varieties of dedicated systems were manufactured by a number of vendors and are currently in use for imaging small laboratory animals at high quality, sensitivity, specificity, and resolution. In developing countries, however, access to such platforms has been limited to none because of a number of reasons including equipment costs or small number of ongoing research projects, not justifying their installations [2]. The investigators of these countries were therefore put in a disadvantaged position compared to their counterparts in the developed countries. Installing a centralized small animal imaging facility within the country or a geographical region would have been an option to rectify the issue, but this has yet to be realized as in the case of the author’s current country of employment. In those instances where the research or discovery demands preclinical imaging, but a special system for performing the task is lacking; the use of clinical radiology systems installed in a typical university hospital has been considered as a viable, but challenging, alternative to support the ongoing preclinical research [3].

The key features of the systems were introduced and the scan protocols used for the acquisitions with specific sets of parameters were described. Practical aspects of making additional modifications and improvements on the systems and scan procedures were analyzed and discussed for gathering optimal anatomical, structural, functional, and molecular data [4]. Methods were suggested for overcoming the limitations of the systems within the context of increasing scan performances in longitudinal studies involving multiple imaging modalities. Extreme modifications in hardware, such as gradient coil insertion or software upgrades, were excluded from the scope of the paper, but additional gadgets or considerations were discussed for longitudinally scanning small animals under anesthesia while monitoring their vital signs.

The synergy between preclinical and clinical imaging

Preclinical imaging, which primarily involves animal models, has long been a cornerstone of preclinical research. It enables researchers to non-invasively visualize and monitor diseases, study biological processes, and test experimental therapies. On the other hand, clinical radiology employs similar imaging modalities but in the context of human patients [5].

By aligning these two fields, researchers and clinicians can harness the full potential of imaging technologies across the translational spectrum. The synergy between preclinical and clinical imaging is characterized by:

Validation of preclinical findings: Preclinical imaging allows researchers to validate their findings in human subjects, increasing the likelihood of successful translation from bench to bedside [6, 7].

Early disease detection: Integrating preclinical imaging techniques into clinical practice can enhance early disease detection, potentially leading to more timely interventions and improved patient outcomes. Treatment monitoring: The ability to track treatment responses in real-time using preclinical imaging can inform clinicians about the effectiveness of therapies, enabling timely adjustments when necessary [8].

Personalized medicine: Combining preclinical and clinical data can facilitate the development of personalized treatment plans based on individual patient characteristics, improving treatment efficacy and reducing adverse effects.

Feasibility and Merits

While the integration of preclinical imaging into clinical radiology presents numerous opportunities, it also poses challenges. These challenges include the need for standardized imaging protocols, data harmonization, and regulatory considerations. However, the merits of this approach are substantial:

Enhanced translational relevance: Aligning preclinical and clinical imaging ensures that research findings are directly applicable to human health, reducing the translational gap [9].

Improved drug development: Preclinical imaging can streamline the drug development process by providing valuable insights into drug efficacy and safety, reducing the likelihood of late-stage failures.

Disease modeling: Animal models can be more accurately tailored to mimic human diseases, aiding in the development of novel therapies and treatment strategies.

Cross-disciplinary collaboration: Bridging preclinical and clinical imaging fosters collaboration between researchers, clinicians, and industry, leading to innovative solutions and faster translation.

Challenges and Future Directions

While the potential of integrating preclinical imaging into clinical radiology is promising, several challenges must be addressed:

Data integration: Harmonizing data from preclinical and clinical imaging sources is essential to facilitate meaningful comparisons and translate findings effectively [10].

Regulatory hurdles: Developing regulatory frameworks that accommodate preclinical imaging data in clinical decision-making is crucial to ensure patient safety and data reliability.

Cost considerations: Implementing preclinical imaging in clinical settings may require significant investments in infrastructure, equipment, and training.

Ethical considerations: Ethical guidelines must be established to address issues such as the use of animal models and patient consent.

Conclusion

The integration of preclinical imaging into clinical radiology represents a significant leap forward in translational medicine. By harnessing the synergy between these two disciplines, researchers and clinicians can improve disease understanding, treatment development, and patient care. While challenges exist, the merits of this interdisciplinary approach are undeniable. As technology advances and collaborations flourish, the future of translational medicine holds the promise of more effective, personalized, and efficient healthcare solutions.
