5158. Utilising
hyperpolarised xenon and dynamic contrast enhanced MRI to assess
the potential pulmonary sequelae of bleomycin therapy - a pilot
study
P. Hughes, R. Kular, M. Tibiletti, G. Collier, L. Smith, R.
Young, J. Wolber, G. Parker, J. Wild, S. Bianchi
University of Sheffield, Sheffield, United Kingdom
Impact: Improved early diagnosis of drug-induced lung
toxicity using a combination of structural and functional
MRI may directly influence how inflammatory and fibrotic ILD
is managed, particularly in patients undergoing novel
therapies.

5159. A
Steady State T1rho-weighted Sequence for Breast MRI at Ultra-low
Field (6.5 mT)
S. Shen, N. Koonjoo, M. Saksena, S. Ogier, K. Jordanova, K.
Keenan, M. Rosen
Massachusetts General Hospital, Charlestown, United States
Impact: T1rho, reflecting macromolecular dynamics, is a
valuable biomarker for tumor imaging. Our study aims to
improve the performance of T1rho-weighted MRI at ultra-low
field, providing a potential non-contrast approach for
breast cancer screening.

5160. LUMBER:
a Custom 3D Printed Mold Platform for Ex Vivo Sampling of
Viable, Clinically Significant Prostate Cancer
C. Du, N. Lanzotti, G. Rac, J. Ellis, V. Chen, M. Picken, G.
Barkan, G. Gupta, S. Shea
Loyola University Chicago, Maywood, United States
Impact: Our 3D mold platform enables harvesting live
cancer from a prostate that has biopsy-proven, positive
MR-targeted lesions and resulted in excellent cancer yield
across 10 patients. The design is intuitive for clinicians
and does not interfere with clinical pathology workflow.

5161. Assessment
of MAGiC abilities of therapeutic selection and prediction on
recurrence risk factors and short-term treatment efficacy in CC
Y. Pei, X. Ou, W. Liu, W. Li
Department of Radiology,Xiangya Hospital of Central South University, Changsha, China
Impact: MAGIC is a promising technique for determination
on tumor staging, RRF prediction and STE prognosis in CC
patients, offering performance equivalent to and even
superior to hr-T2WI and DWI. It should be recommended for
clinical application.

5162. Reproducibility
of T1 and T2 mapping on renal in-vivo data of 3T MRI scanners -
a multi-center and multi-vendor study
A. Strittmatter, A. Raj, S. Pasini, S. Ringgaard, L.
Garcia-Ruiz, G. Villa, R. Echeverria-Chasco, M. Bozzetto, P.
Brambilla, M. Trillin, M. Aastrup, E. Hansen, I. Urdea, L.
Micu, L-M Itu, J. Mora Gutierrez, N. García Fernández, S.
Francis, C. Laustsen, M. Fernandez-Seara, A. Caroli, F.
Zöllner
Heidelberg University, Mannheim, Germany
Impact: To address the standardization challenge of the
MR protocol, assessing repeatability and reproducibility is
essential. Our findings reveal that T1 and T2 MR biomarkers
maintain high repeatability and reproducibility in healthy
volunteers across multiple acquisitions

5163. Lung
T2 mapping using radial turbo spin echo with respiratory gating
using XD-GRASP
S. Triphan, K. Zhang, C. Stewart, H-U Kauczor, M. Wielpütz
University Hospital Heidelberg, Heidelberg, Germany
Impact: Radial TSE has both the advantage that each
projection contains the k-space center which can be used for
gating and that projections can be assembled arbitrarily.
The latter can be exploited to derive more precise and
robust respiratory positions.

5164. Age-modulated
Alterations of Prostatic Morphology predicts Lower Urinary Tract
Symptoms
L. Zhang, W. Mai, D. Zhang, W. Liu, C. Shi
the First Affiliated Hospital of Jinan University, Guangzhou , China
Impact: This study highlights the clinical importance of
MRI-derived morphological indexes, intravesical prostatic
protrusion (IPP), for predicting LUTS in BPH patients at the
age above 50, facilitating early diagnosis and personalized
treatment planning.

5165. Value
of dynamic contrast-enhanced MRI in the diagnosis of acute
radiation-induced rectal injury: a comparison with endoscopy
W-j FAN, Z-q WEN, Q-m LIU, Y-r MA, Y-y LIU, B-l LU, J-p
YUAN, S-p YU, Y. CHEN
The First Affiliated Hospital, Sun Yat-sen University; The Seventh Affiliated Hospital, Sun Yat-sen University, Guangzhou, China
Impact: DCE-MRI is an appropriate non-invasive imaging
technique for diagnosing acute RRI in patients with rectal
cancer.

5166. The
Significance of Quantitative Metrics in Multiparametric MRI for
Assessing Grading and Staging of Graves' Ophthalmopathy
s. wu, L. Yang, Y. Cai, J. Liang, J. Wen, H. Huang, Y. Song,
M. Ma, S. Yu
Department of Medical Imaging, Nanping First Hospital Affiliated to Fujian Medical University and Department of Radiology,Shengli Clinical Medical College of Fujian Medical University,Fujian Provincial Hospital,Fuzhou University Affiliated Provincial Hospital, Fujian,Nanping, China
Impact: A joint parametric model that integrates
multiparametric magnetic resonance quantitative measures
with clinical indicators offers a valid and objective
quantitative index for assessing both the activity and
severity of GO.

5167. Impact
of Reference Image Selection on Ventilation and Deformation
Analysis in functional UTE Lung MRI
S. Westphale, V. Hartung, S. Veldhoen, H. Köstler, T. Bley,
J. Heidenreich
University hospital Würzburg, Würzburg, Germany
Impact: Robust image registration is crucial for
post-processing of functional lung MRI. Understanding the
influence of the reference image on registration and
subsequent ventilation analysis can help to establish
reliable post-processing frameworks.

5168. T1
Hyperintense Cystic Renal Masses in Bosniak v.2019: MR
Subtraction Imaging for Enhancing Interobserver Agreement and
Diagnostic Performance
H. Kang, W. Xu, H. Liu, H. Guo, X. Ning, Z. Liu, H. Wang
First Medical Center of Chinese PLA General Hospital, Beijing, China
Impact: MR subtraction imaging proves to be a valuable
adjunct tool in evaluating T1 hyperintense CRMs,
particularly for less experienced readers. This may enhance
more consistent application of the Bosniak v.2019 and
optimize patient clinical decisions.

5169. Development
of a new imaging test for fat malabsorption
A. Recto, A. Spicer, D. Sills, A. Alhasani, L. Marciani, C.
Hoad, P. Gowland, R. Spiller
University of Nottingham, Nottingham, United Kingdom
Impact: If MRI and MRS could identify and measure fat
malabsorption as an alternative diagnostic technique,
patients would no longer need to take poorly tolerated
diagnostic techniques, this would provide pan-colonic
assessment and reduce patient burden.
