&nbsp;Objective: To observe the role of computed tomographic (CT) scan and ultrasonography (USG) examination in diagnosis of biliary obstruction. Methodology: This cross-sectional study was conducted in 70 patients clinically suspected of obstructive jaundice.<o:p></o:p> Results: The highest incidence of biliary obstruction was found in the age group between 51 and 60 years. 44 out of 70 patients had a benign cause for biliary obstruction, of which choledocholithiasis was the most common cause(25 cases). CT revealed better sensitivity than USG in diagnosing all causes of biliary obstruction except for choledocholithiasis where USG had better sensitivity than CT. No specific diagnosis was obtained in 15 cases evaluated by USG and 10 cases by CT scan.<o:p></o:p> <span style="font-size:10.0pt;&#10;mso-bidi-font-size:9.0pt;line-height:115%;font-family:&quot;Times New Roman&quot;,&quot;serif&quot;;&#10;mso-fareast-font-family:Arial;color:#231F20;mso-ansi-language:EN-US;mso-fareast-language:&#10;EN-US;mso-bidi-language:AR-SA">Conclusion: <span style="font-size:&#10;10.0pt;mso-bidi-font-size:9.0pt;line-height:115%;font-family:&quot;Times New Roman&quot;,&quot;serif&quot;;&#10;mso-fareast-font-family:Arial;color:#231F20;mso-ansi-language:EN-US;mso-fareast-language:&#10;EN-US;mso-bidi-language:AR-SA">Accuracy of USG and CT is high in detecting biliary tree dilatation, with CT scan slightly more accurate than USG. The difference in cost between the two is likely to decline with time and make CT even more attractive and accessible for imaging the hepatobiliary system
