Abstract:
Objective To compare HASTE-MRCP single-slice acquisition technique with ordinary MR cholangiopancreatography (OMRCP) and to assess the clinical application value of HASTE-MRCP single-slice acquisition technique.Methods 48 cases with biliary obstructive diseases and 30 cases without obstructive jaundice were studied with a 3. 0T super conductive unit(Magnetom Trio;Siemens,Germany) that used a body coil. Two acquisition techniques of MRCP were used for all patients . The accuracy of the two kinds of technique were compared. Results OMRCP , single-slice HASTE-MRCP had the same sensitivity and specificity in showing the site and feature of the diseases , the proximal dilated biliarys and distant normal cholangiopancreatic ducts .The diameter of dilated bile ducts at the same level was compared and no significant difference in them. Single-slice HASTE-MRCP had a high spatial resolution ,and shot aquisition time ,but more vessel artifact. OMRCP had high density resoultion ,but more motion artifacts.Conclusion The single-slice acquisition of HASTE-MRCP is an excellent technique in the diagnosis of biliary tract diseases.
