A computer reporting system in radiology at the Massachusetts General Hospital (MGH) uses the direct transcription of dictated reports into the computer with the option of standard reports. This article describes a system in regular use at MGH for reporting dental radiographs in which both the clinical history and the radiographic findings are assembled from canned subunits of standard text. The system covers 80 to 90 percent of all dental radiographs and results in a clear report requiring far less production time than previously.
