High-resolution T1-weighted images were acquired using spoiled gradient recalled sequence on a 3 T MRI system (Tim Trio; Siemens,Erlangen, Germany) with an eight-channel head coil at West China Hospital. The main ...
MRI, or magnetic resonance imaging, utilizes a powerful magnetic field to create detailed images of the brain or spinal cord without causing discomfort or harm to patients. For brain tumor patients, MRI scans are scheduled regularly as part of their medical care, with the frequency adjusted based...

T1ρ imaging protocol T1ρ imaging was performed with spin lock duration (TSL) = 0, 10, 20, 30 ms, spin lock pulse amplitude B1sl = 500 Hz, TR/TE = 5.1/2.4 ms, flip angle = 10°, FOV = 300 × 300 mm2, matrix size...
Liver fibrosis is a public health problem worldwide. There is a need of noninvasive imaging based methods for better diagnosis of this disease. In the current study, we aim to evaluate the potential of T1ρ MRI technique in detecting and characterizing d
Development of this fast and quantitative DGE-MRI technique allows for a more detailed analysis of DGE correlations in the future and potentially enables non-invasive diagnosis, staging and monitoring of tumor response to therapy. In diagnostic imaging it is often beneficial to enhance the contrast ...
MRI, mag- netic resonance imaging; T1, spin-lattice relaxation time; T2, spin-spin relaxation time; TR, repetition time; TE, echo time; TAPIR, T1 mapping with partial inver- sion recovery; CFF, critical flicker frequency; T2*, effective transverse relaxation time; M0, equilibrium magnetization...
Volumetric comparisons between groups were carried out on MRI data from 26 regions of interest (ROIs) pre-selected based on broad cross-species relevance to behavioral and emotion regulation. Graph theory analysis using whole-brain (i.e., 155 ROIs) structural covariance metrics was applied to ...

Reference T1 times on each scanner were determined using standard inversion recovery prepared spin echo sequences at 10 different TIs from 22 to 5,000 ms (TR=10,000 ms, TE=9 ms), with the same FOV, matrix size, and slice thickness as the MOLLI experiment. For precision/reproducibility mea...
