Magnetic resonance cholangiography and ultrasonography in the diagnosis of choledocholithiasis
Özet
The aim of this study is to investigate the diagnostic value of ultrasonography and magnetic resonance cholangiography in chledocholithiasis. Ultrasonography and magnetic resonance cholangiography were performed in 42 patients with findings of obstructice jaundice and suspicion of choledocholithiasis. Results were classified as choledocholithiasis and others. All the results were confirmed by surgery. Findings compatible with choledocholithiasis was detected by magnetic resonance cholangiography in 18 patients. Choledocholithiasis was proven in 17 patients by surgery. However, choledocholithiasis was shown by ultrasonography in 10 patients, all confirmed by surgery. Magnetic resonance cholangiography has 100% sensitivity, 96% specificity and ultrasonography has 58.8% sensitivity, 100% specificity in the diagnosis of choledocholithiasis. Magnetic resonance cholangiography is superior to ultrasonography in the diagnosis of choledocholithiasis. Ultrasonography is the primary imaging modality in biliary system diseases. When ultrasonographic findings are unremarkable, magnetic resonance cholangiography can be used as a noninvasive and reliable imaging modality in the diagnosis of choledocholithiasis.
