imental study on radioactive pathways of hy podermically injected technetium-99m. J Nud Med l992;33:403—407. r several years, a number of au thors have attempted to scientifi cally investigate the field of acupunc ture, specifically the anatomic rele vance ofacupuncture points and their connections, known as “meridians.― It has long been known that skin impedance varies significantly in areas related to the classic acupuncture points (1,2). Correlations have also been made between the acupuncture “meridians―and subjective physical sensations in areas of specific derma tological lesions (3). We have attempted since 1978 to study the migration of radioactive tracers injected at acupuncture points using a scintillation camera coupled to a computer system with image analysis capability (4). Other authors have also examined this subject and obtained reproducible results, includ ing Bagu (5) and Tiberu (6) in Ro mania, Lafont and Munsch in Franc
