  5170. Td-dMRI for early predicting pCR to neoadjuvant short-course radiotherapy followed by camrelizumab and chemotherapy in LARC
L. Zhang, Z. Jin, P. Sun, S. Xu, X. Li
Union Hospital, Tongji Medical College, Huazhong University of Science and Technology, Wuhan, China
Impact: Time-dependent diffusion MRI has potential in characterizing changes of cellular tissue microstructures after short-course radiotherapy and then predicting pCR to neoadjuvant treatment including immunotherapy, which may promote the clinical application of immunotherapy in LARC.
  5171. Association between glymphatic dysfunction and cognitive impairment in patients with hemodialysis
Y. Cui, C. Zheng, B. Xu, J. Lu
Xuanwu Hospital, Capital Medical University, Beijing, China
Impact: Multimodal neuroimaging techniques could provide non-invasive assessment of glymphatic dysfunction in HD patients, providing new insights into the pathophysiology of cognitive impairment in HD patients.
  5172. Motion-Compensated Free-Breathing MRI for GlycoNOE Imaging in the Human Liver
L. Feng, J. Chen, D. Xia, M. Breilyn, S. Lewis, X. Xu
New York University, New York, United States
Impact: This technique can improve glycoNOE imaging in the human liver. The method could be valuable for studying the glycogen distribution and monitoring treatment in patients with glycogen storage disease.
  5173. Assessing Uterine Myomas and adenomyosis with BOLD Imaging After MRI-Guided Focused Ultrasound: Preliminary Findings
P-H Chuang, Y-H Yang, L-W Liu, S-Y Wei, C-W Lee, C-Y Lin, Y-C Lin, S-J Chen
National Taiwan University Hospital, Taipei, Taiwan
Impact: T2*-mapping, which can reveal the variations in oxygenation, would be an effective tool for assessing treatment outcomes of high-intensity focused ultrasound (HIFU) in uterine myomas and adenomyosis, without the need for contrast injection.
  5174. Functional differences in the placenta of pregnancies affected by pre-eclampsia or fetal growth restriction
M. Hall, J. Aviles Verdera, J. Hutter, L. Story
King's College London, London, United Kingdom
Impact: Placental diseases are common in pregnancy. As well as highlighting deviations from normal, placental MRI results vary between conditions. This highlights the potential for MRI to provide better correlation with histopathology and outcomes than is currently possible clinically.
  5175. Evaluating 3D MR Ablation Margins in Hepatocellular Carcinoma after Thermal Ablation Using Open-Source Software
L. J. Qian, L. Wang, T. S. Yang, H. N. Ren, X. H. Gong, Y. Song, Y. Zhou
Renji Hospital, Shanghai Jiao Tong University, School of Medicine, Shanghai, China
Impact: Open-source software can quantify 3D ablation margins at MR images, offering a practical tool in assessing HCC thermal ablation efficacy.
  5176. P53 status combined with MRI findings for prognosis prediction of single hepatocellular carcinoma
H. Huang, G. Zhou, Q. Wu, H. Qiao, S. Chen, S. Hu, Q. Wen
Affiliated Hospital of Jiangnan University, WuXi, China
Impact: The integrated nomogram combining P53 status and preoperative MRI findings can be a valuable prognostic tool for predicting postoperative recurrence of single HCC, suggesting the potential to assist clinicians in developing more aggressive and personalized treatment strategies.
  5177. Noninvasive evaluation of the peristalsis and structure of uterine junctional zone in endometrial fibrosis patients using cine MRI and T2 mapping
Z. Zhou, H. Liang, N. Zhou, W. Chen, P. Jiang
Drum Tower Hospital, Nanjing University Medical School, Nanjing, China
Impact: This study demonstrated the feasibility of cine MRI and T2 mapping in evaluating the peristalsis and microstructure of UJZ which can help clinicians to better understand infertility in patients with different degrees of EF and select the optimal treatment scheme.
  5178. Choice of Segmentation Algorithm to Determine Ventilated Volume Fraction from Oxygen-Enhanced MRI in Cystic Fibrosis and Healthy Volunteers
M. Tibiletti, C. Short, J. Naish, J. Waterton, M. Abkir, T. Semple, S. Padley, J. Davies, G. Parker
Bioxydyn Ltd, Manchester, United Kingdom
Impact: This study provides a direct comparison of segmentation methods for quantifying ventilated lung volume in cystic fibrosis from dynamic oxygen-enhanced MRI. Our results could improve the assessment of lung function in patients, by improving repeatability and sensitivity to disease.
  5179. Nomogram Based on MRI Radiomics Combined with Clinical Features for Assessing Lymphovascular Invasion in Node-Negative Rectal Cancer
L. Peng, X. Zhang, F. Zhang, F. Ma, K. Ai, L. Wang
Gansu University of Chinese Medicine, Lanzhou, China
Impact: The treatment approach for RC without lymph node and distant metastasis but with LVI-positive is equivalent to that for with LNM-positive. The nomogram model offers a non-invasive tool for prediction of LVI, avoiding the risks associated with invasive pathological detection. 
  5180. Free-breathing High Quality Pulmometry MRI: 3D Cones Acquisition with Motion Compensation
B. Li, Q. Liu, J. Xu, H. Gu, H. Li, Y. Dong, Z. Zhong
University of Southern California, Los Angeles, United States
Impact: Free-breathing 3D conical acquisition with motion compensation enables isotropic, high-resolution volumetric lung imaging with reduced motion blurring. This technique is crucial for diagnosing and monitoring lung diseases like COPD and pulmonary fibrosis, significantly enhancing noninvasive diagnostic capabilities and treatment planning.
  5181. Preliminary results on the relation between creeping fat and MRI markers of small bowel lesions in Crohn’s disease
A. Kneib, P. Soullié, A. Basile, L. Peyrin-Biroulet, V. Laurent, F. Odille
INSERM, Université de Lorraine, Nancy, France
Impact: Visceral fat is known to have a specific distribution in Crohn’s disease, however its relation to lesion severity has not been assessed thoroughly. Here we provide preliminary results on this relation using several quantitative MRI markers.
  5182. Four-compartment Restriction Spectrum Imaging model for Preoperative Grading in Endometrial Cancer
T. Yang, Y. Dai, D. Wu, H. Liu, G. Shi
Renji hospital, School of Medicine, Shanghai Jiao Tong University, Shanghai, China
Impact: Four-compartments RSI model demonstrated a potential for preoperative discrimination across all grades of EC lesions, especially between grade-2 and grade-3. Our findings underscore the potential of the RSI model for non-invasive preoperative imaging grading of lesions in EC patients.
  5183. Z-scored Placental T2 Values Facilitate Accurate Risk Stratification for Fetal Growth Restriction
A. Yoshida, Y. Himoto, K. Fujimoto, M. Kikuchi, K. Harada, M. Kirita, Y. Matsumoto, Y. Chigusa, M. Mandai, Y. Nakamoto
Graduate School of Medicine, Kyoto University , Kyoto, Japan
Impact: Compared to T2 values, Z-scored placental T2 values facilitate a more accurate risk stratification of pregnancies with fetal growth restriction. This methodology provides essential guidance for intensive monitoring and optimal timing decisions regarding pregnancy termination.
  5184. Towards Automated Detection and Localization of Radiation-Induced Pneumonitis based on T2-Maps of Lung Cancer Patients
R. Klaar, M. Rabe, K. Begaj, S. Corradini, C. Eze, C. Belka, G. Landry, C. Kurz, J. Dinkel
Department of Radiology, LMU University Hospital, LMU Munich, Munich, Germany
Impact: The acquisition of T2-maps for lung tumor patients 2-3 months after the end of radiotherapy could replace the repeated follow-up CT-scans for these patients and could also allow to automatically identify radiation-induced pneumonitis patients and the affected lung area.
