Pancreas imaging by computed tomography after endoscopic retrograde pancreatography
MP Frick, JF O'Leary, E Salomonowitz, P Stoltenberg, S Hutton and E Gedgaudas
A method using CT after endoscopic retrograde pancreatography (CT-ERP) is
described for pancreatic imaging. When using an ERP technique in the canine
model comparable to that used in humans, small amounts of contrast material
in peripheral pancreatic radicles resulted in enhancement of the pancreas
on CT scans. Nine patients were also studied by CT-ERP. In normal patients
(n = 5) there was opacification of the entire pancreas on CT-ERP images.
The main pancreatic duct was seen on delayed images. In cases of chronic
pancreatitis (n = 2), pancreatic opacification was patchy and
heterogeneous. There was no contrast-material enhancement in areas of
pancreatic carcinomas (n = 2). CT-ERP showed the true extent of carcinoma
better than ERP alone.
