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.

08:10 |  | The Benefit of BI-RADS Sumin Ha Keywords: Body: Breast BI-RADS for MRI allows for standardized reporting, management recommendations, and improved communication between radiologists, clinicians, and patients. The harmonization of BI-RADS across breast imaging modalities enhances cancer detection with higher specificity. With the anticipated release of BI-RADS 6th edition, several changes in MRI BI-RADS are expected, including the elimination of "focus," the addition of T2 hyperintensity description, and new guidance for categorizing additional ipsilateral findings in breast cancer patients. Multiparametric MRI aids in distinguishing benign from malignant lesions. Future research should explore updates in MRI BI-RADS, new imaging sequences such as abbreviated MRI, and BI-RADS 3 audit for MRI. |
08:35 | | Advancing Bladder Cancer Staging and Treatment Response Assessment with VI-RADS: Current Status and Future Perspectives Yuki Arita, Mitsuru Takeuchi Keywords: Body: Urogenital, Contrast mechanisms: Diffusion, Image acquisition: Multiparametric Bladder cancer staging is essential for treatment planning, particularly in differentiating non-muscle-invasive from muscle-invasive disease. The Vesical Imaging-Reporting and Data System (VI-RADS) standardizes MRI assessment, demonstrating high diagnostic accuracy. Initially validated for pure urothelial carcinoma, its use has expanded to variant histology, neoadjuvant chemotherapy (NAC), and immunotherapy response assessment. This lecture will review VI-RADS standardization, the clinical relevance of biparametric versus multiparametric MRI, and the role of peritumoral enhancement in DCE-MRI. Additionally, NAC-VI-RADS and its integration into personalized treatment strategies will be discussed, enhancing bladder cancer risk stratification and treatment monitoring. |

10:15 |  | The Benefit of PI-RADS Yoshiko Ueno Keywords: Body: Urogenital The Prostate Imaging Reporting and Data System (PI-RADS) plays a crucial role in standardizing prostate cancer detection. It enhances the effectiveness of MRI-guided biopsies by improving lesion localization and reducing unnecessary procedures. PI-RADS also contributes to consistent evaluations among radiologists, ensuring reliable interpretations. Furthermore, AI-assisted PI-RADS evaluation supports automated lesion classification, improving both accuracy and efficiency. MRI image quality assessment is also essential for maintaining diagnostic reliability. Overall, PI-RADS provides a structured framework for image interpretation and clinical decision-making, significantly improving prostate cancer diagnosis. This presentation aims to deepen the understanding of PI-RADS and its clinical impact. |
10:40 |  | Biological Diversity of HCC and the Benefit of LI-RADS Kumi Ozaki Keywords: Body: Liver, Cross-organ: Cancer Hepatocellular carcinoma (HCC) displays a variety of imaging findings because HCC is a malignancy with variable biologic aggressiveness based on the tumor grade, presence or absence of vascular invasion, and pathologic and molecular classification. Therefore, the imaging diagnosis of HCC has its complexities and challenges. Liver Imaging Reporting and Data System (LI-RADS) has addressed this situation. LI-RADS is a standardized system for interpreting and reporting liver imaging findings, particularly for patients at risk for HCC, and enhances the specificity of diagnosis by categorizing the imaging findings of HCC, which presents with diverse characteristics, from LR-1 to LR-5. |
