Figure 4From: In vivo migration of labeled autologous natural killer cells to liver metastases in patients with colon carcinomaNormal parenchyma and tumor lesions. Patients were given 99mTc phytate before i.v. (open bars) or i.a. (full bars) 111In-Oxine labeled A-NK administration. The tumor/parenchyma labeling ratio (Y axis) was calculated as the ratio between the 111In counts in metastatic (no 99mTc phytate uptake) and normal (99mTc phytate uptake) SPET areas.Back to article page
