Evaluation of a novel contrast-enhanced fluoroscopy protocol for endoscopic retrograde cholangiopancreatography in a phantom model (with video).

ABSTRACT:

Objectives

This study evaluated a novel contrast-enhanced (CE) fluoroscopy protocol for endoscopic retrograde cholangiopancreatography, which optimizes image processing to enhance contrast of devices and contrast media. We compared the CE protocol with the conventional standard protocol to assess its potential for reducing radiation exposure while improving image visibility.

Methods

The study utilized a multidirectional fluoroscopy unit and phantoms to evaluate the new CE protocol against the conventional protocol. Comparisons included radiation dose rates, spatial resolution, and concentration resolution under various fluoroscopic conditions. The investigation aimed to determine if the CE protocol offered improved visibility while potentially reducing radiation exposure.
