Recent improvement of multislice computed tomography (CT), electrocardiogram (ECG) gating, and dedicated cardiac reconstruction algorithms allow us obtain excellent cardiac imaging. The esophagus is located next to pulsating heart or aorta, high-resolution and motion-free images of esophageal cancer and adjacent structures can be obtained using this technique. Staging of cancer is important not only in the treatment decision but also prediction of prognosis. The reconstruction methods are slightly different among manufacturers, we used a CT scanner made by GE Medical. Using this technique, much better information in the staging of esophageal cancer was obtained. The spatial resolution of ECG-gated CT examination and that of routine CT examination will be discussed, too.
