Diagnostic accuracy of ultrasonography compared with magnetic resonance cholangiopancreatography in the detection of choledocholithiasis.

Purpose: The aim of this study is to compare the diagnostic accuracy of ultrasonography (US) with magnetic resonance cholangiopancreatography (MRCP) in the diagnosis of choledocholithiasis in context of laboratory blood test values.

Methods: This retrospective study included patients who underwent both MRCP and US as part of their choledocholithiasis workup. MRCP findings, reviewed by two board-certified radiologists, laboratory findings, and US reports were collected.
