Abstract
Objective To evaluate the hypotonic spiral CT manifestation of normal Vater's ampulla to provide an important reference for diagnosing ampulla disease.Methods Forty-eight cases of normal ampulla confirmed by operation or follow-up survey were studied with hypotonic spiral CT.Results Of these 48 cases,45 were good in hypotonic effect.The longest duodenal diameter on the slice of duodenal papilla was(2.39±0.57) cm.There was no significant difference between male group and female group.Of these 48 cases,46 were good in showing duodenal papilla,the longest diameter of duodenal papilla was(0.42±0.23)cm.The most diameter of duodenal papilla between male group and female group had no significant difference.Conclusion Hypotonic spiral CT manifestation of normal ampulla shows duodenum is dilated moderately,and duodenal papilla could be seen clearly,and normal duodenal papilla is divided into semicircular,mastoid and compressed.
