Abstract Objective To study the application value of dynamic dual-contrast imaging of the esophagus in the diagnosis of early esophageal cancer. Methods Conventional double-contrast angiography and dynamic double-contrast angiography were performed on patients suspected of early esophageal cancer by digital gastrointestinal machine, and 40 cases of early esophageal cancer confirmed by endoscopy or surgical pathology and with both types of angiographic data were randomly selected and analyzed in a double-blind method to evaluate the reliability of their diagnosis. Results The lesions were mainly characterized by uneven thickness, distortion, irregular niches and filling defects, and the softness and diastolicity of the esophageal wall in the lesion area were reduced or even disappeared. Dynamic dual-contrast imaging showed significantly better local function of early esophageal cancer than conventional dual-contrast imaging, and there was a statistically significant difference between the two (χ² = 4.50 Р < 0.05). Conclusion Dynamic dual-contrast angiography has high value in the diagnosis of early esophageal cancer, and is a more ideal examination method.

To study the role of esophageal dynamic double contrast radiography (DDCR ) in diagnosing early esophageal carcinoma (EEC ). Methods The patients with clinical suspected EEC underwent conventional double contrast radiography (CDCR ) and DDCR using digital fluoroscopic imaging unit. The radiographic materials including CDCR and DDCR in 40 cases with EEC proved by endoscopy or pathologic histology were analyzed by a blind study ,and the reliability of CDCR and DDCR in patients with clinical suspected EEC was also assessed. The radiographic materials including CDCR and DDCR in 40 cases with EEC proved by endoscopy or pathologic histology were analyzed by a blind study ,and the reliability of CDCR and DDCR evaluated. Results The major findings of EEC included the mucosa irregularity and tortuous, small niches and The major findings of EEC included the mucosa irregularity and tortuous, small niches and filling defect, the soft and expansive extent of esophageal wall reduced or disappeared. superior to CDCR (χ²=4.50, Р
