A direct comparison between subcutaneous and intralymphatic injections for lymphoscintigraphy.

Lymphoscintigraphy using 99mTc colloids has been proposed as a simple adjunct to lymphangiography. To validate the technique of subcutaneous injection we performed a direct comparison between intralymphatic and subcutaneous administration of 99mTc-antimony colloid. In all cases excellent correspondence was obtained between the two techniques.
