Journal ArticleDOI
Manganese ferrite nanoparticle micellar nanocomposites as MRI contrast agent for liver imaging
Jian Lu,Shuli Ma,Jiayu Sun,Chunchao Xia,Chen Liu,Zhiyong Wang,Xuna Zhao,Fabao Gao,Qiyong Gong,Bin Song,Xintao Shuai,Hua Ai,Zhongwei Gu +12 more
TL;DR: Manganese doped superparamagnetic iron oxide (Mn-SPIO) nanoparticles were used to form ultrasensitive MRI contrast agents for liver imaging and brought significant liver contrast with signal intensity changes of -80% at 5min after intravenous administration.
Journal ArticleDOI
Saturation power dependence of amide proton transfer image contrasts in human brain tumors and strokes at 3 T
Xuna Zhao,Zhibo Wen,Fanheng Huang,Shilong Lu,Xianlong Wang,Shuguang Hu,Donglin Zu,Jinyuan Zhou,Jinyuan Zhou +8 more
TL;DR: The results suggest that the saturation power of 2 μT is ideal for APT imaging of these two pathologies at 3 T with the existing clinical hardware.
Journal ArticleDOI
Low molecular weight alkyl-polycation wrapped magnetite nanoparticle clusters as MRI probes for stem cell labeling and in vivo imaging.
Gang Liu,Zhiyong Wang,Jian Lu,Chunchao Xia,Fabao Gao,Qiyong Gong,Bin Song,Xuna Zhao,Xintao Shuai,Xiaoyuan Chen,Hua Ai,Zhongwei Gu +11 more
TL;DR: An efficient SPIO probe has been developed for mesenchymal stem cells labeling and tracking at optimized low dosages with high efficiency, and the probe may be useful to label other biologically important cells for imaging studies.
Journal ArticleDOI
APT-weighted and NOE-weighted image contrasts in glioma with different RF saturation powers based on magnetization transfer ratio asymmetry analyses.
Jinyuan Zhou,Jinyuan Zhou,Xiaohua Hong,Xiaohua Hong,Xuna Zhao,Xuna Zhao,Jia-Hong Gao,Jia-Hong Gao,Jing Yuan +8 more
TL;DR: To investigate the saturation‐power dependence of amide proton transfer (APT)‐weighted and nuclear Overhauser enhancement‐weighting image contrasts in a rat glioma model at 4.7 T, data are collected on rats with and without cancer.
Journal ArticleDOI
Chemical exchange saturation transfer MR imaging of Parkinson’s disease at 3 Tesla
TL;DR: CEST imaging signals could potentially serve as imaging biomarkers to aid in the non-invasive molecular diagnosis of PD, and protein-based CEST signals in basal ganglia increased in PD patients.
