[Fluorogram using digital X-ray cineradiography].

We discussed the usefulness of fluorogram obtained using digital X-ray cineradiography (digital-cine-fluorograpy) in the diagnosis of dysphagia, comparied with that of video-fluorograpy. Digital-cine-fluorograpy produces five frames per second. A qualitative evaluation comfirmed that five frames per second was sufficient to grasp movement during swallowing in clinical setting. Digital-cine-fluorograpy imaging was also convenient for clinical practice in that the medical records can be accessed from any workstation. Although the maximum photography time (around 10 seconds) is limited and a higher exposure dose is required, we concluded that digital-cine-fluorograpy is a useful tool for the diagnosis of dysphagia.
