Alternatives to PTC include Magnetic Resonance Cholangiopancreatography (MRCP) and Endoscopic Retrograde Cholangiopancreatography (ERCP). MRCP is non-invasive and uses magnetic resonance imaging to visualize the biliary and pancreatic ducts but may not be as detailed as PTC. ERCP, although more invasive, combines endoscopy and fluoroscopy to diagnose and treat conditions of the biliary or pancreatic ductal systems. The choice of procedure depends on the clinical scenario and the expertise available.
