- Abstract
- Purpose: We aimed to determine the visibility of bile ducts of the caudate lobe (B1s) and right/left (R/L) dissociation on contrast-enhanced T1-magentic resonance cholangiography after gadolinium ethoxybenzyl diethylenetriaminepentaacetic acid administration (CE-T1-MRC) in live liver donors. Materials and Methods: In 300 live liver donors who underwent CE-T1-MRC, the visibility and R/L dissociation of B1 were evaluated. Confidence level of B1 visibility and depiction of the presence of R/L dissociation on axial and coronal reconstruction images were compared. Strength of agreement between R/L dissociation on MRC and that on intraoperative cholangiography was evaluated. Results: At least 1 B1 was visible on CE-T1-MRC in 142 of 300 subjects (47.3%; a total of 195 B1s; 0.64 [SD, 0.80], 0-4 branches per person). Of 195 subjects with visible B1, 55 ducts showed R/L dissociation (28.2%; right-to-left crossover, n = 28; left-to-right crossover, n = 27). The confidence level of B1 visibility on axial images of MRC was significantly higher than that on coronal images of MRC (P < .001). Of 55 B1s with R/L dissociation, axial images were superior to coronal images in depicting B1 crossover in 31 and vice versa in 2 (equal between axial and coronal images in 22). The agreement for R/L dissociation between CE-T1-MRC and intraoperative cholangiography was excellent (κ = 0.819; 95% CI, 0.722-0.917). Conclusion: Bile ducts of the caudate lobe with R/L dissociation can be occasionally identified on CE-T1-MRC. Axial reconstruction is superior to coronal counterpart. © 2019 Elsevier Inc.
