Predictors of radiation exposure in percutaneous transhepatic cholangiodrainage: a multifactorial analysis integrating fluoroscopy time, cumulative dose, and dose-area product

This study aims to delineate the predictors influencing three complementary radiation metrics—fluoroscopy time (FT), cumulative dose (CD), and dose-area product (DAP)—during percutaneous transhepatic cholangiodrainage (PTCD) to inform targeted radiation safety protocols. We retro...
