ABSTRACT
Multiple systems (musculoskeletal, brain, and medulla, among others) have widely demonstrated the usefulness of MRI as noninvasive diagnostic and guided tool for surgical interventions. Mainly, these great outcomes of MRI are due to its high intrinsic contrast resolution and the potential application of multiple sequences to achieve excellent tissue characterization. However, abdominal application of MRI techniques has not been increased until recent years when MRI sequences have been evolved improving its performance, reducing its exposure time, and increasing its spatial resolution. Nowadays, these improved features of MRI allow to detect and to analyze the most of these abdominal organs and structures that are highly deformable and suffer usually complex morphological changes and movements all over the abdominal cavity. For this reason, its use on postsurgical applications, with rising interest in abdominal interventions, is fully implemented in some surgical protocols and is increasing in others. In this sense, depending on the surgical speciality some specic techniques such as MR urography, MR cholangiopancreatography, and MR angiography have been developed using MRI.
