In order to evaluate ultrasonographic changes of the pancreas with aging, the size, the parenchymal echo and the duct of the pancreas were investigated in 526 subjects free of pancreatic diseases.
The maximal anterior-posterior diameter of the pancreas was measured respectively at head, body and tail under real-time observation using the linear electronic scanner. The sizes of three parts of the pancreas significantly decreased with aging.
The parenchymal echo of the pancreas showed a homogeneous and obviously higher echogenecity compared with one of the liver in elders, and the increased parenchymal echogenecity was seen more frequently with aging.
The ultrasonographic ability of visualization of the pancreatic duct significantly decreased with aging, however, any significant change was not found in the diameter or the margin of the pancreatic duct.
