Diffusion Weighted Imaging of the Gastrointestinal Tract

This book explains how diffusion weighted imaging has been incorporated in routine MRI examinations of the abdomen and pelvis: though its clinical role is still evolving, it is already considered an important tool for the assessment of rectal cancer treatment response, as was confirmed in recent ESGAR consensus statements. The standardization and clinical validation of quantitative DWI related biomarkers are still in progress, although certain efforts have been undertaken to establish imaging guidelines for different clinical indications/body parts.

The book reviews the technical aspects and clinical applications of DWI in imaging of the GI tract, and provides specific technical details (imaging protocols, artefacts, optimization techniques) for each GI tract division. This volume is mainly intended for radiologists who are interested in abdominal radiology, as well as radiology residents. Given that magnetic resonance physics is complex and can be cumbersome to learn, the authors have made it as simple and practical as possible.

  Nikolaos Papanikolaou

Sofia Gourtsoyianni obtained her Medical Degree from the Medical School of the University of Pecs, Hungary in 2001. She spent the first 18 months of her Radiology residency at the Institute of Clinical Radiology, Ludwig Maximilian University, Munich, Germany, and then continued at the Radiology Department of the University Hospital of Heraklion, Greece.

In June 2010 she obtained her PhD from the University of Heraklion, Crete, Greece on Diffusion Weighted Magnetic Resonance Imaging in Staging of Rectal Cancer.

She completed a one-year Research Fellowship in CT Applications at the Department of Computed Tomography, Beth Israel Deaconess Medical Center, Harvard Medical School, Boston, USA in 2011.

During the period 2013-2017 she worked as a Consultant in Radiology at Guy’s & St Thomas’ NHS Foundation Trust after having spent a year as a Clinical Research Fellow at the Division of Cancer Imaging, School of Biomedical Engineering and Imaging Sciences (BMEIS), King’s College London working with Prof Vicky Goh. She currently holds an Honorary Clinical Lecturer appointment with King’s College London and works as a Consultant Radiologist at Konstantopouleion General Hospital in Athens, Greece.

Dr. Gourtsoyianni’s main areas of clinical and research interest are abdominal/GI and oncologic imaging. She has (co) authored 28 peer reviewed papers and 7 book chapters. She has delivered more than 80 national/international invited lectures at radiological and clinical society meetings around the world.

Nikolaos Papanikolaou is the Head of Computational Clinical Imaging Group at Champalimaud Foundation in Lisbon, and an affiliated researcher of the Karolinska Institute in Stockholm. He received his Ph.D. in Medicine from the University of Crete, Greece. He has been actively involved on clinical MRI research for the last 25 years.

Dr. Papanikolaou has published 63 papers in international peer reviewed journals, authored 18 book chapters, and held 81 invited lectures for international congresses and educational courses. He is an honorary member of SEDIA and a fellow member of ESGAR. His main research focus is on Diffusion Weighted Imaging, Radiomics, Modelling and Post Processing techniques.
