1. 证明在肺癌高发的患者中，当参照真值标准对原发性和转移性病灶的图像判读进行比较时，SPECT/CT（99mTc-EC-DG）的敏感性或特异性指标非劣于 PET/CT（18F-FDG）。 2. 进一步证明 99mTc-EC-DG 在患者中的安全性。

This study will compare how well a new radiolabeled imaging agent ECDG compares to the current testing for coronary artery disease (radiolabeled Sestamibi) during a rest and stress cardiac test as documented from results of a coronary angiogram (if performed).

The purpose of this study is to determine if the images of the primary lesions of lung cancer and any metastatic lesions seen from the investigational SPECT/CT 99mTC-EC-DG scans are the same as the PET/CT 18F-FDG scans.
