Tumor migration of A-NK cells. SPET analysis from patient #1 performed 10 min after ^99mTc phytate (top) and 6 h after subsequent i.a. (A, bottom) or i.v. (B, bottom) injection of ¹¹¹In-Oxine-labeled A-NK cells. A "cold" (no uptake) area corresponding to tumor tissue is observed before i.a. or i.v. A-NK injections (A and B, top). This area is ¹¹¹In-positive after i.a. (A, bottom), but not after i.v. (B, bottom) injection of A-NK cells. Three consecutive axial sections are shown.
