Intrabiliary MR imaging

The goal of this research is to illustrate the potential role of interventional MR imaging in a clinical setting. As shown by this study, IBMR is feasible, is well tolerated, and positively affects patient management. IBMR allowed for significantly decreased field of view and high in-plane resolution and provided contrast between the biliary lumen and adjacent structures with high diagnostic accuracy. This technique enabled clinicians not only to improve imaging of the biliary tree but also to make a more accurate diagnosis. Based on this pilot work, there are several potential avenues of further expansion for IBMR. For example, enhanced imaging of the biliary tree may allow for monitoring of new biliary treatment regimens such as photodynamic therapy or molecular targeting [23,24]. In addition, this technique may also foster development of innovative new percutaneous procedures [25] that may eventually treat some biliary disorders under MR imaging guidance.
