Abstract:

Aim: the aim of this study was to evaluate the diagnostic possibilities of the dynamic MDCT in the differential diagnosis of gastric diseases compared with conventional upper gastrointestinal barium study and endoscopy

Materials and methods: 130 patients with different gastric lesions underwent dynamic MDCT The detection rate of the gastric lesion and the diagnostic accuracy of each method were calculated by the use of surgical and histopathologic results as reference standards.

Results: diagnostic accuracies of methods in the differential diagnosis of gastric tumors with exophytic growth were: endoscopy - 91%, barium study - 50%, MDCT - 87%; in the differential diagnosis of ulceration: endoscopy - 78%, barium study - 84%, MDCT - 93%; and in the diagnosis of diffuse type of gastric cancer: endoscopy - 82%, barium study - 75%, MDCT - 100%.

Conclusion: integration of the dynamic MDCT in algorithms of diagnostics of gastric lesions can improve detection rates of stomach diseases and the accuracy of their differential diagnosis.
