Comparison of Ultrasonography and Computed Tomography to Evaluate the Causes of Biliary Obstruction

Objective: to watch how an ultrasonography (USG) examination and a computed tomographic (CT) scan are used to assess the reasons of biliary blockage. Materials And Methods: A total of 57 individuals who were clinically suspected of having obstructive jaundice participated in this cross-sectional investigation. Results: The age range of 40 to 49 years old had the highest incidence of biliary blockage and the mean (±SE) age of the patients was 48.4 ± 1.6 yearsAll patients had elevated levels of serum alkaline phosphatase and serum bilirubin. USG revealed 42 true negative instances, 2 false negative cases, and 13 true positive cases with no false positives for the assessment of pancreatic mass. According to this, a CT scan revealed a true positive in 15 instances and a false positive, false negative, or true negative in 42 others. Sensitivity and specicity of USG in detecting pancreatic mass were 80 and 97.6%. CT scan showed 93.3% sensitivity and 97.6% specicity. In case of gallbladder (GB) mass USG found true positive in 20 and 1 false positive. In 36 situations, there was neither a true negative nor a false negative. Moreover, a CT scan showed improved sensitivity. The USG was unable to nd any periampulla cases. Conclusion: Both USG and CT scans are highly accurate in identifying biliary tree dilatation; however, CT scans are somewhat more accurate than USGs. With time, the cost differential between the two should narrow, making CT an even more appealing and practical imaging option for the hepatobiliary system.
