title: Gastroesophageal scintigraphy with and without compression.
abstract: This study compares the results of radionuclide gastroesophagography performed by the compression and computer-assisted noncompression techniques. The overall accuracy of the compression and noncompression methods was 71% and 84%, respectively. The use of computer processing significantly enhances the ability to detect minor degrees of reflux and may explain the better results obtained with the noncompression method. Other advantages of the noncompression technique include its technical ease and uniformity and the acquisition of more physiologic data for comparison with results of the acid reflux test.
