In conventional indirected parameter estimate, such as Weighted Least Square Method, the changing activity of the injected radiotracer is conventionally measured through multiple consecutive PET image reconstructions. The image of the radioactivity distribution in each frame is reconstructed independently and the whole set of frames is then used to estimate the distribution of the physiological parameter of interest by the application of an appropriate pharmacokinetic model to the time radioactivity curve either of appropriately selected functional regions or of each image element.

Radioactivity of 〓Tc-MIBI incepted by A549DDP cells in controlling group, Rh2 group, DDP group and Rh2＋DDP group account for 0.94%, 1. 08%, 1. 13% and 2. 0% respectively of the total radioactivity. There was evident difference between the former three groups and Rh2＋DDP group P＜(0.05 . Radioactivity of 〓Tc-MIBI incepted by A549 cells was 2. 38% of the total radioactivity, obviously higher than that in controlling group (P ＜O. 05). conclusions: gensenoside Rh2 of no toxicity concentration can reverse resistance of lung adenocarcinoma A549DDP cells to cisplatin.
