Nisar, S. Raichandani, A. Pratapneni, P. Ghanouni, E. Pollom, V. Sheth Department of Radiology, Stanford University, Palo Alto, United States Impact: Gadolinium washout may be useful in conjunction with T2-weighted and diffusion-weighted images for accurate assessment of rectal cancer treatment response.
		Computer Number: 99 2823. Non-invasive prediction of KRAS mutation in rectal cancer using hybrid intravoxel incoherent motion and diffusion kurtosis model View Presentation Video J. YUAN, M. Liu, W. Tan Shuguang Hospital Affiliated to Shanghai University of Traditional Chinese Medicine, Shanghai, China Impact: The hybrid IVIM-DKI model, especially the K value, demonstrates potential as a non-invasive imaging biomarker for KRAS mutation status in rectal cancer. This approach could guide treatment decisions and evaluate prognosis without invasive biopsies, potentially improving patient care and outcomes in rectal cancer management.
		Computer Number: 100 2824. Improve Model Performance Rectal Cancer Staging by Radiomics Analysis of Diffusion-weighted Imaging and T2-weighted Imaging View Presentation Video Y-C Chen, C-F Hsieh, S-C Lin, C-C Chang, C-J Juan, Y-J Liu, H-H Peng National Tsing Hua University, Hsinchu, Taiwan Impact: Compared to extracting features from DWI or T2WI solely, radiomics analysis of combinations of DWI_b800+T2WI or DWI_b800+FS-T2WI exhibited better AUC and TNR in identifying rectal cancer patients ≥T3. A bounding-box was the best strategy for determining the analyzed region.
		Computer Number: 101 2825. Virtual magnetic resonance elastography and fractional order calculus model for assessing proliferation status in rectal carcinoma N. Meng, Y. Cui, X. Wang, X. Chen, J. Guo, L. Xie, M. Wang Henan Provincial People’s Hospital & Zhengzhou University People’s Hospital, Zhengzhou, China Impact: The vMRE, FROC, and DWI can effectively differentiate between high- and low-proliferation rectal carcinoma. and a composite diagnostic tool consisting of µ_MRE, D, and β may serve as a promising biomarker to help make optimal clinical decisions.
		Computer Number: 102 2826. Imaging features and prognosis after curative resection of proliferative hepatocellular carcinoma with LR-4/5 and LR-M Y. Xie, Z. Liu, X. Zhang, X. Zhao Nantong University, Nantong Third People’s Hospital, Affiliated Nantong Hospital 3 of Nantong University, Nantong, China Impact: Combining LI-RADS classification and proliferation helps to stratify the risk of recurrence after curative resection in patients with solitary HCC.
		Computer Number: 103 2827. In-vivo detection of rectal cancer at low field using field cycling imaging View Presentation Video A. Alamri, N. Senn, L. Samuel, R. Mitchell-Hay, D. Lurie, G. Ramsay, L. Broche University of Aberdeen, Aberdeen, United Kingdom Impact: This FFC-NMRD technique could complement existing imaging modalities by addressing limitations in detecting post-therapy changes in rectal cancer, enabling non-invasive diagnostics. Also, it holds potential to improve personalized treatment, guiding more effective therapies and enhancing patient outcomes.
		Computer Number: 104 2828. FOCUS-MUSE DWI in Primary Rectal Cancer: Comparison with FOCUS, MUSE, and Single-shot EPI DWI W. Feng, L. Zhu, K. Wang, J. Dai, Q. Ma, H. Shen, F. Yuan, H. Zhang Ruijin Hospital, Shanghai Jiao Tong University of Medicine, China, Shanghai, China Impact: Our study showed FOCUS-MUSE provided improved image quality of DWI for primary RC T staging. The application of FOCUS-MUSE DWI may be beneficial for evaluating and managing RC.
		Computer Number: 105 2829. T1-Mapping with High-Spatial-Resolution T2-Weighted Imaging Differentiates Mucinous from Nonmucinous Adenocarcinoma in Rectal Cancer Y. Liu, Z. Wen, Y. Chen, S. Yu, Y. Ma, X. Yang, Y. Wu The First Affiliated Hospital, Sun Yat-sen University, Guangzhou, China Impact: This study suggests combining HR-T2WI and T1-mapping as a non-invasive method for diagnosing MC in rectal cancer, potentially reducing false-negative biopsies. Future research can explore its role in treatment response prediction and outcome assessment.
		Computer Number: 106 2830. The evaluation of MR staging of rectal cancer by using amide proton transfer weighted (APTw) imaging View Presentation Video Y. Gao, J. Liu, J. Lian, B. Pan, J. Qiu Peking University First Hospital, Beijing, China Impact: APTw imaging provides information on rectal cancer staging.
		Computer Number: 107 2831. Improved Characterization of Liver Lesions with Hepatobiliary Phase Free-Breathing, Phase Sensitive Inversion Recovery MRI View Presentation Video Y. Muslu, J. Heidenreich, J-P Grunz, T. Cashen, S. Mandava, A. Pirasteh, D. Hernando, S. Reeder University of Wisconsin-Madison, Madison, United States Impact: GA-enhanced PSIR-T₁w MRI improves T₁ contrast and offers variable T₁w imaging in a single acquisition, enabling both detection and characterization of lesions with a single T₁w image acquisition.
		Computer Number: 108 2832. Efficient Assessment of CR to Neoadjuvant Therapy in Locally Advanced Rectal Cancer using Amide Proton Transfer Weighted MRI: a Diagnostic Study L. Zhang, Z. Jin, P. Sun, Y. Liu, X. Li Union Hospital, Tongji Medical College, Huazhong University of Science and Technology, Wuhan, China Impact: Our study revealed the clinical significance of APTw MRI as a promising imaging modality for assessing CR to NAT in LARC. APTw MRI can provide unique insights into tumor metabolism and microenvironment, surpassing the capabilities of traditional MRI.
		Computer Number: 109 2833. Assessing Liver Fibrosis with Gd-EOB-DTPA-enhanced B1 Inhomogeneity-corrected VFA T1 mapping: Comparison with US Shear-wave Elastography Y. Li, C. Fu Department of Radiology,Zhongshan Hospital of Fudan University, Shang hai, China Impact: It is essential to apply a noninvasive and accurate method for predicting liver fibrosis stages. Liver stiffness measurement using US shear-wave elastography is superior to T1 relaxation times obtained from Gd-EOB-DTPA-enhanced T1 mapping for staging liver fibrosis.
		Computer Number: 110 2834. Single-Site Experience of Liver Fat and Iron Quantitation with a 2D Flip Angle Modulated CSE-MRI Sequence in the Clinical Setting View Presentation Video E. Milshteyn, A. Guidon, J. Tang, S. Reeder, D. Hernando, N. Nakrour, M. Harisinghani, A. Mojtahed GE HealthCare, Boston, United States Impact: With its free-breathing nature and reproducible PDFF and R2* values compared to gold standard 3D CSE-MRI, 2D FAM CSE-MRI shows promise as a routine tool in clinical liver fat and iron quantitation.
		Computer Number: 111 2835. Application Value of MR Elastography in the Identification of Benign and Malignant Liver Lesions and Prognostic Prediction of Malignant Tumors View Presentation Video X.
