Overview
This session explores the significance and application of standardized reporting systems in MRI diagnostics, focusing on PI-RADS, BI-RADS, LI-RADS, VI-RADS, and O-RADS. By examining both the challenges and benefits of each system, participants will gain a comprehensive understanding of their role in improving diagnostic accuracy and patient management.

Target Audience
Radiologists, medical physicists, and other healthcare professionals involved in MRI diagnostics who want to enhance their understanding and application of standardized reporting systems.

Educational Objectives
As a result of attending this course, participants should be able to:
• Evaluate the principles and guidelines of PI-RADS, BI-RADS, LI-RADS, VI-RADS, and O-RADS in MRI diagnostics, comparing their strengths and limitations;
• Apply these standardized reporting systems to improve diagnostic accuracy and patient management in various clinical scenarios; and
• Assess the challenges and benefits associated with each RADS system to optimize their use in clinical practice.

07:45		The Challenge with PI-RADS × Video Permission Withheld Tharakeswara Bathala Impact: PI-RADS faces many challenges, including subjective criteria causing reader variability, inconsistent image quality, technical differences across institutions, indeterminate lesions with uncertain cancer risk, and limitations detecting certain tumors.
08:10		The Benefit of BI-RADS × Video Permission Withheld Sumin Ha Impact: The standardized lexicon and reporting of breast MRI using BI-RADS will be discussed. With the anticipated release of BI-RADS 6th edition, changes in the MRI BI-RADS will be reviewed. Finally, the benefits of multiparametric breast MRI will be explored.
08:35		Advancing Bladder Cancer Staging with VI-RADS: Current Status and Future Perspectives View Presentation Video Yuki Arita, - -, - - Impact: This lecture reviews the evolving role of VI-RADS in bladder cancer staging, with updates on biparametric MRI, peritumoral enhancement, and NAC response assessment, highlighting its growing value in precision imaging and treatment decision-making.
09:00		O-RADS Rebecca Rakow-Penner
09:25		Break & Meet the Teachers
09:55		The Challenge with BI-RADS Wendy DeMartini
10:20		The Benefit of PI-RADS × Video Permission Withheld Yoshiko Ueno Impact: PI-RADS standardizes prostate cancer diagnosis, improving MRI-guided biopsy accuracy and reducing unnecessary procedures. AI enhances PI-RADS evaluation as a support tool for radiologists. Standardization, inter-reader agreement, and MRI quality assessment further improve diagnostic reliability.
10:45		Biological Diversity of HCC and the Benefit of LI-RADS View Presentation Video Kumi Ozaki Impact: LI-RADS is a classification system for liver lesions which is used in patients with cirrhosis and chronic HBV, and enhances diagnostic specificity by categorizing the diverse imaging characteristics of HCC into five levels, ranging from LR-1 to LR-5.
11:10		The Challenge with LI-RADS Amitkumar Choudhari
