In Vivo Visualization of the Pericardium Meridian with Fluorescent Dyes

Figure 6

ICG fluorescent line after injection at PC7 (a). One hour after injection, the fluorescent line appears as shown in (b). Sixteen hours later, it is weaker (c). After 24.5 hours, the line in (d) was traced and compared with acupoints (e). PC5, PC4, and PC3, marked as pink cross, closely approximated to the red traced line.
