relationship between the tumor and the facial nerve; knowing
this relationship helps reduce the risk of facial nerve
injury during surgery.

analysis of synthetic MRI to distinguish benign from malignant
sinonasal tumors: correlations with histopathologic factors
Y. Xiang, Y. Zhang, X. Li, Y. Xiong, G. Han, X. Ren
Second Affiliated Hospital of Xi'an Jiaotong University, Xi'an, China
Impact: Histogram analysis of SyMRI quantitative maps
may be recognized as a noninvasive and free-contrast method

1903. Water/fat
Separated Distortion-Free Diffusion-Weighted Imaging in the Head
and Neck
X. Zhou, P. Lee, A. Nurdinova, N. Fischbein, N. Pham, B.
Hargreaves
Stanford University, Stanford, United States
Impact: Diffusion-prepared FSE using shot-weighted
reconstruction and multi-echo water/fat separation is robust
to significant B0 variations,
with relatively high SNR efficiency. This enables reliable
use of DWI for assessing cancer and other abnormalities in
the head and neck, complementing contrast-enhanced imaging.

1904. Assessing
Gravity’s Impact on Choroid Plexus Position with 1.5 T Rotatable
Superconductive Cryogen-free MRI
Y. Wang, S. Ke, J. Li, J. Zeng, J. Zhang, S. Niu, Y. Zhu, C.
Yao, J. Zheng, T. Meersmann, L. Zhao, C. Wang
University of Nottingham Ningbo China, Ningbo, China
Impact: This study reveals the gravitational influence
on the position change of the choroid plexus and
demonstrates its morphology in a typical standing condition.
These findings could have implications for future research
on CSF exchange and flow in different postures.

1905. Morphometric
analysis of black bone MRI for radiation-induced bone injury in
the head and neck
N. West, L. McCullum, S. Mulder, T. Salzillo, R. He, Y.
Ding, J. Wang, M. Chen, S. Lai, C. Fuller
The University of Texas MD Anderson Cancer Center, Houston, United States
Impact: Black bone MRI shows promise in cortical bone
visualization, which has direct potential to detect early
anatomical changes caused by radiation. Its sub-millimeter
voxel size allows for enhanced spatial resolution compared
to standard-of-care CT and T2-weighted MRI.

Department of Radiology, National Cancer Center/National Clinical Research Center for Cancer/Cancer Hospital, Chinese Academy of Medical Sciences and Peking Union Medical College, Beijing 100021, China, Beijing, China
Impact: Two model-free parameters simplified the
clinical process without compromising the efficacy.
vMRE/S-index and TGT/CPRI shown for the first time to
predict long-term survival in NPC, helping with clinical
treatment decisions.
