To illustrate the added role of contrast-enhancedT1-weighted (T1w) magnetic resonance cholangiography (MRC) using hepatobiliary contrast agents in blunt liver trauma.

Incidence Injury to the biliary tree remains a complex problem with significant long-term morbidity and poor outcomes. Biliary injury in the setting of abdominal trauma is a rare complication, with a reported prevalence of 2.8%–7.4% in patients who sustain blunt hepatic injuries or penetrating injuries caused by simple direct force (e.g. knife wound) or by a complex, indirect injury (e.g. gunshot wound). Biliary tract injuries are associated with multiple organ injuries, most commonly, hepatic, splenic, and duodenal injuries, which have a reported prevalence of 91%,...

The current algorithm in blunt liver trauma with suspected bile extravasations in hemodynamically stable patients candidates to MRI includes, in addition to standard MRstudy of the liver, a pre-contrast T2-weighted (T2w) MRC, which highlights the biliary tree (Tab. 4). Furthermore, a contrast-enhanced T1-weighted (T1w) MRC using hepatobiliary contrast agent is performed, after aconventional dynamic study, at90-120 minutes after intravenous administration of gadobenate dimeglumine (Gd-BOPTA) or at 15-20 minutes after intravenous administration of gadoxetic acid (Gd-EOB-DTPA), obtaining thehepatobiliary delayed phase imaging. The excretion into the biliary...

We recommend to perform MR with IVhepatobiliary contrast agents inhemodynamically stablepatient with blunt liver trauma andsuspected bile extravasations. Contrast-enhanced MRC using hepatobiliary contrast agentsis a recently developed technique that increases preoperative accuracy when identifying and locating extravasations of bile in liver trauma.
