Which imaging technique enhances the visualization of tumors during VTP?

Fluorescence imaging is particularly effective in enhancing the visualization of tumors during vascular targeted photodynamic (VTP) therapies due to its ability to detect specific fluorescent markers that are selectively taken up by tumor cells. In VTP, photosensitizers are used that can accumulate in tumor tissues. When exposed to specific wavelengths of light, these photosensitizers emit fluorescence, making it easier to visualize the tumor and assess the effectiveness of the therapy in real-time.

This imaging technique provides valuable information on the spatial distribution of the tumor and the extent of the treatment response, allowing for more accurate targeting of therapy and assessment of therapeutic outcomes. The specificity and sensitivity of fluorescence imaging make it a preferred choice in the context of VTP, where clearly identifying tumor boundaries and monitoring treatment effects are crucial for successful intervention.
