Fig. 1.

Anterior and posterior images of lymphoscintigraphy with 99 mTc-phytate showing radiotracer progression slightly slowed on the left lower limb, collateral and tortuous lymphatic vessels on the right limb, and exuberant concentration on the inguinal chain. These images were achieved using a GE gamma camera, Discovery NM630. Anterior and posterior projection images of the lower limbs were acquired 15 and 60 minutes after subcutaneous injection of 37 MBq (1 mCi) of 99mTc-phytate applied in the dorsal region of the feet. The gamma camera had a large field of view and was equipped with a parallel hole low-energy high-resolution collimator (±1% window centered on the 140-keV energy peak of 99 mTc).
