Overview
Magnetic resonance imaging has spawned the new field of MRI cholangiography. With or without contrast material, MRI is able to show the bile in the bile ducts from many different angles and can be as good a modality for detecting stones in the bile ducts as ultrasound imaging, excluding the much more interventional transhepatic cholangiogram. Problems with MRI include limited availability in certain areas, limited cholangiographic skills and experience, and relatively high costs.[1]
Intraoperative cholangiography
Intraoperative cholangiography (IC) has an estimated sensitivity of 59 - 100% for diagnosing choledocholithiasis, with a specificity of 93 - 100%. However, it is highly operator-dependent and is not routinely performed by many surgeons.[2][3]
