TL;DR: The use of enteric contrast media for CT, MRI, and ultrasound in infants, children, and adolescents is reviewed and practical ways to optimize the imaging examination and the patient experience should be employed where possible are shared.
Abstract: OBJECTIVE. Enteric contrast media are commonly administered for diagnostic cross-sectional imaging studies in the pediatric population. The purpose of this manuscript is to review the use of enteric contrast media for CT, MRI, and ultrasound in infants, children, and adolescents and to share our experiences at a large tertiary care pediatric teaching hospital. CONCLUSION. The use of enteric contrast material for diagnostic imaging in infants and children continues to evolve with advances in imaging technology and available enteric contrast media. Many principles of enteric contrast use in pediatric imaging are similar to those in adult imaging, but important differences must be kept in mind when imaging the gastrointestinal tract in infants and children, and practical ways to optimize the imaging examination and the patient experience should be employed where possible.

TL;DR: The role of 3D-CASP in preoperative surgical planning in liver surgery is described and an innovative imaging strategy for identifying liver segments during laparoscopic liver surgery by applying a fluorescent imaging method is proposed.
Abstract: Background: Advances in surgical and in imaging technology permit the performance of complex tumour resections in a safe and oncologically correct manner. To date, this has mainly implicated refined preoperative imaging methods, such as three-dimensional computer-assisted planning (3D-CASP). With the advent of modern hybrid operating rooms, intraoperative imaging has spread and various techniques of intraoperative image guidance have been developed. Methods: We review recent advances in intraoperative image guidance. We also delineate the role of intraoperative imaging techniques such as intraoperative ultrasound and computed tomography for real-time image guidance in laparoscopic liver surgery. Results: Our review shows that advances in intraoperative imaging accompany the increasing use of laparoscopic approaches in visceral surgery. For the liver surgeon working laparoscopically, the loss of tactile sensation and the complex three-dimensional anatomy of the human liver make 3D-imaging techniques and intraoperative image guidance indispensable. We describe the role of 3D-CASP in preoperative surgical planning in liver surgery. Conclusion: An innovative imaging strategy for identifying liver segments during laparoscopic liver surgery by applying a fluorescent imaging method is proposed.

TL;DR: The basic principles of PA imaging, its implementation in the different modalities and examples of applications to morphological, functional and molecular imaging are explained and the challenge of recovering quantitative information from PA image data sets is described.
Abstract: Photoacoustic (PA) imaging is an emerging imaging technology with potential for preclinical biomedical research and clinical applications. PA imaging, which relies on the generation of broadband acoustic waves via the absorption of intensity-modulated light in tissue, offers the combination of strong optical contrast and high spatial resolution provided by ultrasound. For excitation wavelengths in the visible and near-infrared region, image contrast is predominately due to haemoglobin. Exogenous contrast agents, such as dyes or genetically expressed absorbers, can be used to obtain targeted molecular contrast. Over the past decade, PA imaging has rapidly evolved into different microscopy and tomography modalities, while novel methodologies have led to a variety of exciting applications. This chapter explains the basic principles of PA imaging, its implementation in the different modalities and provides examples of applications to morphological, functional and molecular imaging. Furthermore, the challenge of recovering quantitative information from PA image data sets is described.
