Subcutaneous injection of 99mTc pertechnetate at acupuncture points K-3 and B-60.

Abstract

The acupuncture points are known to be morphologically related to the nerves and vessels. Yet the physiological role of blood vessels in the formation of acupuncture points remains unknown. With subcutaneous injection of 99mTc pertechnetate at the acupuncture points K-3 and B-60 and with intra-acupuncture point injection of 99mTc pertechnetate at K-3 and B-60, a lower-limb venography like what was obtained by intravenous injection of 99mTc macroaggregated albumin was demonstrated in the present study. It seems that some acupuncture points do play a role in drainage of tissue fluid from soft tissue into the veins.
