A novel respiratory gating method for oncologic positron emission tomography based on bioimpedance approach.

abstract：OBJECTIVE:The Response Evaluation Criteria In Solid Tumors (RECIST) is the most used radiological method for evaluating response after peptide receptor radionuclide therapy (PRRT) in patients with neuroendocrine tumors. This method may give too positive estimates of response in slow growing tumors as it allows a substa...
