Purpose : To determine the hemodynamics of the pancreas by investigating the
enhancement patterns of pancreatic parenchyma, as seen on sporal CT, after the
administration of vareous amounts of contrast medium, and to determine optimal scan
time by knowing the peak time of mormal pancreatic parenchyma.
Materials and Methods : Between January 1995 and April 1997 55 cases of normal
abdominal CT with dymamic enhancement study on pancreas, the subject were 38
cases(28 persons) with good image, aged 21-65 years, men were twenty-one and
women were seven. Non-ionic contrast medium, 30ml(n=5), 60ml(n=9), 990ml(n=7), and
120ml(n=7) were injected at a rate of 3ml/sec. From 20 sec. after the start of injection,
15 images were obtained at 3-sec intervals. Before and after injection, R.O.I. was
applied to each image, and for the aorta and pancreatic parenchyma. Hounsfield
units(H.U.) were measured ; time of enhancement and maximal H.U. were also
measured.
Results : After 30, 60, 90, and 120m1 of contrast medium injection, mean maximal H.U.
of pancreatic parenchyma was 36¡¾7, 54¡¾6, 68¡¾ 13, and 92¡¾8, respectively: mean value
at peak parenchymal enhancement of the pancreas was 27¡¾3, 32¡¾3, 42¡¾3, and 52¡¾3,
respectively. Time intervals of maximal enhancement of aorta and pancreatic parenchyma
sould not be obtained in 30ml injection, but 5.4¡¾2.5, 4.2¡¾ 1.6, and 6.0¡¾2.1 sec in 60, 90,
and 120ml injection, respectively.
conclusion : Maximal H.U. of parenchymal enhancement of the pancreas is directly
proportional to the amount of injected contrast midium and the peak time of
parenchymal enhancement was 12sec after the injection of contrast material.
Time interval of maximal enhancement of aorta and pancreatic parenchyma was 5.2 ¡¾
