Learn about the state-of-the-art in oncological imaging
all from the comfort of your home or workplace!

Since 2015, ESOI has been proudly offering high quality webinars given by world class speakers on various topics in oncologic imaging. Our live webinars have been very well received by our members with consistently high turnout and engagement from participants all across the globe. After the presentation, you can even ask questions in real time!

ESOI webinars are oriented towards different levels of expertise, a wide array of topics, and are increasingly becoming more multidisciplinary.
A number of our webinars are carried out in collaboration with medical societies such as ESSO and ESTRO as well as other radiological subspecialty societies.
Young radiologists are also included in the webinar series with special sessions addressing relevant topics for residents.

In addition to the live broadcast, the lectures are uploaded to the Member Area (with an approximate one month delay) so they can be (re)viewed by active ESOI members at their own convenience.
To date, we have more than 70 full length lectures (with in-depth discussions and Q&A)!

Recommended Bandwidth
The website offers you to check your bandwidth. We strongly recommend
• Upload min. 6Mbit required bandwidth (relevant for speakers, moderators sharing their video&audio signal)
• Download min. 6Mbit required bandwidth
Also, we recommend a cable internet or a wireless connection with full signal.
Please note: Shared bandwidth (e.g. hospital, universities) will result in lower bandwidth for each user.

ESOI does not issue individual certificates of attendance for the webinars.

Webinar Testimonial – Ludovit S.

“If you are thinking about joining ESOI I can only recommend it. The year 2020 was challenging and the society really helped me to cope with these demanding circumstances, not only in cancer diagnostic, but with the management of patients in the context of the pandemic. The webinars and Q&A helped to lessen the need of personal interactions with renowned doctors in the field of cancer diagnostics and insights how to manage patient flow in the shadow of a contagious disease were useful too. I wish everyone the strength to overcome difficulties yet to come and hope to see everyone well and healthy at the next OIC.”

Ludovit S. from Dunajska Streda, Slovakia attended 11 ESOI webinars in 2020

Upcoming Webinar

Rectal Cancer: A multi-disciplinary approach to imaging

Regina Beets-Tan, Geerard Beets, Corrie Marijnen; Amsterdam/NL

Tuesday, January 26, 2021 | 18:00 CET

MR Imaging of rectal cancer influences treatment decision and impacts patient’s outcome. It is crucial that radiologists not only understand how to read and interpret images but also know how these findings impact clinical decision making. This joint ESOI/ESTRO/ESSO webinar approaches imaging from a multidisciplinary view. Attendees will learn about the multidisciplinary team management, the relevant questions from clinicians and how radiologists can answer these. The teachers will be a team of surgeon, radiation oncologist and radiologist experts in rectal cancer management. Short lectures will be followed by case based discussions among the teachers and attendees, in this way simulating a multidisciplinary meeting.

1. To learn about the clinically relevant questions in the multidisciplinary management of rectal cancer
2. To know how radiologists can answer these questions

Prof. Dr. Regina Beets-Tan, MD, PhD, chairs the Dept of Radiology at The Netherlands Cancer Institute in Amsterdam. Her clinical expertise is in oncologic and abdominal imaging. Her research lines are in multiparametric MR imaging of cancer, Artificial Intelligence and Interventional oncology. Beets -Tan is 1st Vice President of the ESR, President of ESGAR and Past President of ESOI. She is a member of the EU Mission Board for Cancer. She represents ESR in the board of the European CanCer Organisation (ECCO). Beets-Tan is personally engaged in various activities of clinical societies. She is an honorary member of the ESTRO and of the Chilean Colorectal Surgical Society. As ESOI and ESGAR president she started formal collaboration between ESOI and medical oncological societies ESMO, ESTRO, ESSO, ESDO and EACR and between ESGAR and GI and hepatobiliary societies ESCP,EPC,ESP,ESPGHAN,EDS,ESDO and ESGE because it is her belief that multidisciplinarity is the key for better patient care.

Geerard Beets is Professor in Surgical Oncology and Chair of the Department of Surgery at the Netherlands Cancer Institute in Amsterdam. He has an academic affiliation with Maastricht University in the Netherlands, where he previously worked as Director of the Oncology Center. His clinical field of expertise is colorectal cancer, with multidisciplinary research focused on rectal cancer: MR imaging of rectal cancer, outcome research and organ preserving treatment of rectal cancer. This resulted in many papers, PhD theses and invited lectures. There is a large and successful research collaboration with his wife, Regina Beets-Tan, Professor of Radiology and Chair of the Department of Radiology at the Netherlands Cancer Institute. Geerard Beets is a faculty member of national and international colorectal and oncological societies, and member of the editorial team of several colorectal and oncological journals.

Professor Marijnen started her training as radiation-oncologist in 1994 in the Academic Hospital Leiden. During her residency, she started with her PhD, which she achieved with honors in 2002. After working for 4 years in the Netherlands Cancer Institute, she became chair of the department of Radiotherapy at Leiden University Medical Center. During that time, she was closely involved in the HollandPTC, the joined protonfacility of the LUMC, ErasmusMC and TU Delft. In 2019 she moved back to the Netherlands Cancer Institute, where she is currently working as chair of the department of Radiotherapy.
In the past 15 years, Corrie Marijnen focused her research on the treatment of rectal cancer, with special attention for toxicity and quality of life. On April 10th 2002, she defended her thesis “Radiotherapy in Rectal Cancer” based on the results of the international TME study, which investigated the value of short-term preoperative radiotherapy in rectal cancer. In addition to this, better patient selection for adjuvant treatment, improvement of treatment techniques and target volume delineation are topics addressed in her projects. Patient preferences and computer-assisted shared decision making are her other fields of research. These topics were extensively addressed in her inaugural speech on the 30th of October 2009, titled: “From X-rays to Arrays”. Since 2009, she has played an important role in several large (inter)national trials for locally advanced rectal cancer, as well as in trials concerning organ preservation for early rectal cancer.
