Summary

This study compares the carbon footprint of two tests used to diagnose gallstones: endoscopic ultrasound (EUS) and magnetic resonance cholangiopancreatography (MRCP). Both are equally accurate, but MRCP uses more energy and larger machines. Researchers will measure the total greenhouse gas emissions from each procedure, including electricity, supplies, and patient travel. The goal is to find out which test is kinder to the environment without compromising care.
