G. Reuther et al., MR-CHOLANGIOPANCREATICOGRAPHY IN SINGLE-S HOT PROJECTION - TECHNIQUE AND RESULTS OF 200 EXAMINATIONS, RoFo. Fortschritte auf dem Gebiete der Rontgenstrahlen und der neuenbildgebenden Verfahren, 165(6), 1996, pp. 535-543
Purpose: Evaluation of utility and value of a selective projection tec
hnique for bile and pancreatic ducts in MRI. Material and methods: 200
patient examinations of the pancreaticobiliary duct system using a tu
rbo-SE pulse sequence in ''single-shot'' technique were evaluated in r
etrospect concerning anatomic display and diagnostic accuracy compared
to surgery, ERCP, i.v. cholangiography, ultrasound and clinical cours
e. Results: Non-dilated ducts allowed visualisation of gallbladders in
78%, common bile ducts in 97%, cystic ducts in 80%, intrahepatic main
ducts in 71% and pancreatic main ducts in 69%. When dilatation was pr
esent, all common bile, intrahepatic main and pancreatic ducts were vi
sible. Display of cystic ducts and gallbladders with a detection rate
of 69 and 85%, respectively, did not improve. Sensitivities for diagno
sing papillary stenoses (n = 6), pancreatic ductal stenoses and dilata
tion (n = 13), compressions and dilatations of the biliary tree (n = 3
3) as well as for one choledochal cyst were 100%. Choledudolithiasis c
ould correctly be predicted in 11/15 cases (73%), cholecystolithiasis
in 71/120 cases (59%). Conclusion: ''Single-shot'' MR-cholangiopancrea
ticography is a fast and non-invasive modality which can replace i.v.
cholangiography and restrict the indication for ERCP to therapeutic in
dications and problem cases.
