In Vivo Visualization of the Pericardium Meridian with Fluorescent Dyes

Figure 4

ICG migratory path after injection at PC5. After injection of ICG at PC5 (a), fluorescent line develops and is imaged here at 2.5, 5, and 18 hours (c–e). Five hours after injection, fluorescent lines are observed in both the forearm and upper arm (d). The fluorescent line was traced with a pen (b), passing by PC4 and PC3. Eighteen hours after injection, the fluorescence on the upper arm is still visible (e). The photo and video were taken with a mobile phone with long-pass filter above 780 nm.
