Objective:

To investigate the application of wide-band high frequency ultrasonography in displaying the pancreas in preschool children

and to study the influencing factors.

Methods:

A total of 54 preschool children were divided into four groups according to age. 3.5 MHz and 5-10 MHz transducers were used to measure the pancreatic size and thickness of abdominal wall.

Results:

There was no significant difference in pancreatic size between 3.5 MHz transducer and 5-10 MHz transducer (

P

0.05). The wide-band high frequency ultrasonography was more sensitive in displaying the pancreatic ducts than 3.5 MHz routine u

ltrasonography (

P

0.01). The thickness of abdominal wall was correlated with the diameter differences of pancreatic head

body and pancreatic tail (

r

=0.39

P

=0.004;

r

=0.28

P

=0.04;

r

=0.40

P

=0.003). The height

weight

body mass index and age were not correlated with pancreatic size measured by wide-band high frequency ultrasonography (

P

0.05).

Conclusion:

The wide-band high frequency ultrasonography can not only measure the pancreas in preschool children exactly but also better display the internal structures.
