Recent Advances in Perfusion Assessment in Clinical Oncology Using Hyperspectral Imaging

Perfusion assessment is critical in clinical oncology, particularly in tumor characterization, intraoperative decision making, and postoperative outcome predictions. Hyperspectral imaging (HSI) has emerged as a promising, non-contact, non-invasive, and contrast-free modality capable of capturing spatial and spectral information related to tissue oxygenation and hemoglobin distribution. This study provides an up-to-date review of recent advances in the use of HSI for perfusion monitoring in clinical oncological applications, with a special focus on its adoption in laparoscopic surgeries, brain tumor delineation, and head and neck cancer interventions. The integration of HSI into surgical workflows and its potential to reduce complications are discussed. Overall, while HSI is emerging as an appealing, real-time, quantitative perfusion imaging modality, a lack of standardized protocols and interpretation guidelines pose the most significant challenges. Addressing these gaps through multicenter clinical trials is essential for advancing the routine use of HSI in oncological surgery.
