Radiopharmaceuticals are useful to evaluate effectiveness of cancer treatments as well as diagnosis of diseases. (99m)Tc-Glucoheptonate has high sensitivity for imaging lung cancer tissues. In this study, the potential use of (99m)Tc-glucoheptonate for monitoring apoptosis related to chemotherapeutic agents is
