About This Trial
MRCP and EUS are diagnostically equivalent in detecting CBD stones among patients with intermediate risk, as shown in a landmark RCT. However, MRI-based imaging is power-intensive, requiring large infrastructure and long scan durations. EUS, a less energy-consuming and portable procedure, has the added advantage of enabling same-session ERCP, reducing the need for repeat procedures.
