Esophageal motility was evaluated from the analysis of six consecutive swallows. A sum image was generated comprising the representative information of an entire study. Calculation of emptying rates and characterization of the bolus behavior was performed from the sum image and the single swallow data. In 86 patients investigated, liquid and solid-phase(More)
A better understanding of scintigraphic findings may lead to a wider acceptance of esophageal transit studies. The purpose of this study, therefore, was to correlate standard manometric parameters with the quantitative and qualitative characteristics of liquid and semi-solid bolus transport. Twenty-nine patients were simultaneously investigated with(More)
UNLABELLED This study investigates whether systematic analyses of methodological issues contribute to improve and renew the diagnostic role of quantitate esophageal scintigraphy. METHODS Forty-seven patients with normal (n = 26) and pathologic (n = 21) esophageal function were studied with scintigraphy and manometry, using the latter findings as the gold(More)
A condensed imaging technique was applied to gastric emptying studies to investigate (a) whether different types of motility disorders may be distinguished by characteristic image patterns and (b) whether the findings obtained provide additional information compared to standard quantitative measurements. Condensed images and quantitative data of gastric(More)
Established single-swallow techniques for the assessment of oesophageal motility disorders encompass a high potential of falsely positive/negative findings caused by the considerable variability between single swallows. In this study, therefore, a new form of parametric oesophageal scintigraphy (POeS) is introduced which allows simultaneous assessment of(More)
