摘要：

The authors describe the initial application for tumor staging with an inline system with a positron emission tomographic (PET) scanner and a multi-detector row helical computed tomographic (CT) scanner combined in one machine. Fifty-three patients underwent imaging with four CT tube currents and PET emission and transmission data acquisition. Stepwise analysis of coregistered images revealed a significant (P <.05, McNemar test) improvement in lesion classification between PET images alone and coregistered images from the PET-CT examination.
