Value of magnetic resonance imaging versus spiral CT in the diagnosis of biliary diseases

  Objective  To explore the application value of magnetic resonance imaging technique (MRIT) and spiral CT (SCT) in the diagnosis of biliary diseases.

  Methods  The clinical data of 68 patients with biliary tract disease confirmed with imaging diagnosis in our hospital was retrospectively analyzed. The diagnostic accuracy of the two examination methods in the localization and characterization of biliary obstructive diseases was compared.

  Results  MRIT and SCT had an accuracy rate of 100.00% in the diagnosis of biliary obstructive disease, and there was no between-group difference. The diagnostic accuracy rate of benign biliary obstructive disease and the overall diagnostic accuracy rate of biliary obstructive disease by MRIT examination were significantly higher than SCT (P < 0.05). The two examination methods both had higher accuracy rate in diagnosis of malignant biliary obstructive diseases, and the difference showed no statistically significant (P>0.05).

  Conclusion  SCT and MRIT have higher accuracy rate in the localization and qualitative diagnosis of biliary obstructive diseases. In contrast, MRIT has higher accuracy in the diagnosis of benign biliary obstructive diseases, especially bile duct stones.
