Which BL point is located 3 cun lateral to the midline at the level of the spinous process of T9, corresponding to Ganshu BL-18?

Which BL point is located 3 cun lateral to the midline at the level of the spinous process of T9, corresponding to Ganshu BL-18?

• A. Bl 46
• B. Bl 47
• C. Bl 48
• D. Bl 50

Answer: (B)

Locating back points uses a vertical arrangement along the spine with a standard lateral offset. The back-Shu point for the liver (Ganshu) sits at the level of the ninth thoracic vertebra and is normally found about 1.5 cun lateral to the posterior midline. In this item, the description places the point 3 cun lateral to the midline at the T9 level, which, in this chart’s scheme, lines up with the same transverse plane as Ganshu BL-18 and identifies the corresponding BL point as BL-47. So the described location matches that BL point on the 3-cun-lateral line at T9. The other options would be at different lateral distances or different vertebral levels, so they don’t fit this described plane.
