Journal ArticleDOI

Samantha Mikaiel,James Simonelli,Xinzhou Li,Yu-Hsiu Lee,Yong Seok Lee,Yong Seok Lee,Kyunghyun Sung,David S.K. Lu,Tsu-Chin Tsao,Holden H. Wu +9 more
TL;DR: This study evaluates the feasibility of a remote‐controlled hydrostatic actuator system for MRI‐guided targeted needle placement in the narrow space of magnetic resonance imaging.
Journal ArticleDOI
Prediction of myocardial signal during CINE balanced SSFP imaging.
TL;DR: A signal model that takes into account the effects of non-ideal slice profile, off-resonance, and radio-frequency transmit variation on myocardial signal behavior is presented and can be used for the optimization of pulse sequences and protocols.
Journal ArticleDOI
Fast 3D T2 -weighted imaging using variable flip angle transition into driven equilibrium (3D T2 -TIDE) balanced SSFP for prostate imaging at 3T.
TL;DR: The objective was to develop a fast 3D T2‐weighted sequence for prostate imaging at 3T using a variable flip angle transition into driven equilibrium (T2‐TIDE) scheme.
Journal ArticleDOI
Radiofrequency transmit calibration: A multi-center evaluation of vendor-provided radiofrequency transmit mapping methods.
Yannick Bliesener,Xinran Zhong,Yi Guo,Michael A. Boss,Ryan Bosca,Hendrik Laue,Caroline Chung,Kyunghyun Sung,Krishna S. Nayak +8 more
TL;DR: To determine the accuracy and test-retest repeatability of fast radiofrequency (RF) transmit measurement approaches used in Dynamic Contrast Enhanced Magnetic Resonance Imaging (DCE-MRI), and if unaccounted for, B1 + inhomogeneity can severely impact tracer kinetic parameter estimation.
Journal ArticleDOI
Characterization of Uterine Motion in Early Gestation Using MRI-Based Motion Tracking.
Thomas Martin,Carla Janzen,Xinzhou Li,Irish Del Rosario,Teresa Chanlaw,Sarah Choi,Tess Armstrong,Rinat Masamed,Holden H. Wu,Sherin U. Devaskar,Kyunghyun Sung +10 more
TL;DR: Investigation of the characterization of uterine activity during MRI in the second trimester of pregnancy using MRI-based motion tracking found the dominant direction of the uterine contraction and maternal motion was the superior to the inferior direction during early gestation.
