Background:
Obstructive jaundice is a common clinical condition requiring timely identification of the level and cause of biliary obstruction. Ultrasonography (USG) and Computed Tomography (CT) are widely used initial imaging modalities, while Magnetic Resonance Cholangiopancreatography (MRCP) provides non-invasive high-resolution visualization of the biliary tree. This study evaluates the diagnostic accuracy of MRCP compared to USG and CT.
Methodology:
A cross-sectional study was conducted at Hi-Tech Medical College & Hospital, Bhubaneswar, from July 2025 to December 2025. Sixty patients with clinical and biochemical features of obstructive jaundice were included. The mean age was 52.6 ± 14.3 years, with 60% males and 40% females. All patients underwent USG, CT, and MRCP. Final diagnosis was confirmed using ERCP, histopathology, or surgical findings.
Results:
MRCP demonstrated higher sensitivity (94.6%) compared to CT (85.1%) and USG (78.4%) (p<0.001). Specificity of MRCP was 92.3%. It showed superior detection of choledocholithiasis and malignant obstruction. Overall diagnostic accuracy was highest for MRCP (93.3%).
Conclusion:
MRCP is superior to USG and CT in diagnosing obstructive jaundice and accurately identifying the level and cause of obstruction. It should be considered the preferred non-invasive imaging modality following initial ultrasonography.
