Official figures released by the European Society of Radiology (ESR) show that 17,262 participants from 122 countries attended ECR 2023. This represents a rise of 14% compared with last year, but it is still a much lower figure than was recorded in 2019.
There were 11,004 professional attendees and 6,258 industry representatives at ECR 2023, but the ESR did not specify how many of these delegates attended virtually.
He's in there somewhere! Can you spot ECR President Prof. Adrian Brady? This remarkable photo would not have been conceivable in the heat of the COVID pandemic. All images courtesy of Sebastian Kreuzberger/ESR.Italy accounted for the largest number of registrations (1,041), followed by Germany (785), U.K. (633), Austria (595), Spain (515), Netherlands (416), Switzerland (389), Romania (372), France (336), Poland (295), Belgium (286), Denmark (247), USA (246), Sweden (238), China (236), Portugal (214), and Norway (205).
In the wake of the huge earthquake that hit Turkey and Syria on 6 February 2023, it was impressive that Turkey was responsible for 187 ECR registrations, although it is unclear how many of these attended virtually.
Ukraine accounted for 115 registrations, while 66 delegates came from the Russian Federation. A total of 171 registrants came from Ireland, one of the host countries.
Standing room only: Lecture halls in the Austria Center Vienna were generally quite full throughout the five-day congress.ECR 2022 was held in July, and it attracted 10,093 professional attendees and 4,987 industry representatives, making a total attendance both online and in-person of 15,080. That compares with 14,776 professional and 981 industry attendees, totaling 15,757 at the online-only edition of ECR 2021.
The last in-person meeting, ECR 2019, saw 14,602 professional attendees and 8,637 industry representatives, for a total attendance of 23,239.
"After all the disruptions to lives in recent years, it was wonderful to see the halls and rooms of the Austria Center crowded with busy, enthusiastic, happy attendees," noted ECR 2023 President Prof. Adrian Brady from Cork, Ireland, in an ESR statement.
"Onsite feedback from Congress participants was very positive, and watching attendees, I sensed that the future of radiology is in excellent hands, with young colleagues ready to continue the success and constantly increasing clinical relevance of and delivery of value by our specialty," he added.
Over 250 companies took part in the technical exhibition at ECR 2023.The industry exhibition featured over 250 of the world's biggest companies in medical imaging. With a more integrated approach, involving many companies taking space within the main halls of the Austria Center, the industry presented state-of-the-art technology and services, and held numerous interactive demonstrations, informative sessions, and social events for attendees.

![Examples of ultrasound findings and techniques. (A) Images in a 39-year-old male patient with a mass in the left thigh. The mass is heterogeneous on the B-mode US image (compared with the patient in D) and showed increased microvascularity (superb microvascular imaging [SMI]) and shear-wave elastography (SWE) values. Undifferentiated pleomorphic sarcoma was diagnosed at biopsy (with pleomorphic rhabdomyosarcoma in surgical specimen). (B) Images in an 18-year-old male patient with a mass in the left leg. The mass is hypoechoic on the B-mode image, with no other findings suggestive of malignancy. The lesion is in contact with the cortex of the tibia, which is slightly irregular. CT revealed a doubtful anteromedial tibial erosion. The microvascular study demonstrated high vascularization, suggestive of malignancy. Periosteal Ewing sarcoma was diagnosed with both histologic and immunohistochemical confirmation. (C) Images in a 69-year-old female patient with a lump growing on the outside of the left leg. Multiple SWE examinations were performed (please note the high values obtained in the measurements, whereas the color map highlights the stiffness relative to adjacent tissues). SMI showed areas of increased vascularization to target for sampling. Undifferentiated spindle cell sarcoma was diagnosed at biopsy, with residual leiomyosarcoma in the surgical specimen after neoadjuvant therapy. (D) Images in a 56-year-old female patient with a mass in the right thigh. The mass is heterogeneous at both B-mode ultrasound (similar to patient A) and MRI (coronal T2-weighted spectral attenuated inversion recovery [SPAIR]; T1-weighted pre-contrast and postcontrast imaging), which even shows uptake after the administration of paramagnetic contrast material, which is traditionally suggestive of malignancy. Low values at SMI and elastography are suggestive of benignity. Spindle cell lipoma was diagnosed at biopsy, with atypical spindle cell lipomatous tumor in the surgical specimen.](https://img.auntminnieeurope.com/mindful/smg/workspaces/default/uploads/2026/08/images-radiol250278fig2.APCFLSvX6p.jpg?auto=format%2Ccompress&fit=crop&h=100&q=70&w=100)
