Colorectal cancer liver metastasis
This video shows the application of the Quest Spectrum Platform for the detection of colorectal cancer liver metastasis.
After the injection of ICG the metastasis are shown as green rings around the metastasis. This procedure can be performed both open as shown here, and laparoscopically.
Near-infrared fluorescent imaging identifies significantly more and smaller tumors during resection of colorectal cancer liver metastasis, preventing recurrences in a subset of patients. Given its safety profile and low expense, routine use of ICG can be considered until tumor targeting fluorescent tracers are clinically available.

Motivations to choose ICG in case of colorectal cancer liver metastasis:
- In 13% of the cases more metastasis are detected
- Lesions are undetectable by preoperative computed tomography, intraoperative ultrasound, visual inspection, and palpation
- Only superficial lesions are detected but it seems that the majority of lesions are superficial
