T1-FFET1 weightedFast Field Echo. In this context, 'contrast enhanced' refers to thepulse sequence, it does not mean enhancement with acontrastagent. •View the DATABASE results for 'Spoiled Gradient Echo Sequence' (11). Further Reading: ...
In most cases cancer does not yield a high signal on T2-weighted images; thus, these sequences can be useful in the differentiation between benign and malignant lesions. However, as most of these lesions can also be identified on T1-weighted images, there is no evidence as yet of added va...
As a correlate of the disturbance of the cartilage structure and composition, Mosheret al. showed that running induced an initially significant decrease in the superficial chondral T2 values in the FTJ37. Subburajet al.42also described a significant decrease in T1rho- and T2-relaxation times afte...
Structural MRI T1 and T2: The MP2RAGE78 sequence was acquired for assessment of brain structure with a voxel resolution of 1 mm (isotropic). Resulting T1-weighted images and quantitative T1 maps can be used for analyses of gray and white matter (e.g., cortical thickness, voxel-based ...
(longitudinal) and T2 (transversal) relaxation times of surrounding water protons to indirectly produce a signal-enhancing effect [25]. The efficiency of an agent to shorten relaxation times is called relaxivity, which is dependent on the ligand surrounding the Gd3+ion (see later) and influenced ...
Routine T2-weighted, fat-suppressed T1-weighted, and opposed-phase T1-weighted images were acquired before contrast administration. Gadoxetic acid (Primovist or Eovist, Bayer AG, Germany) was administered intravenously with a power injector at a rate of 1 mL/s (0.025 mmol/kg BW). Post-contrast...
First, not only T1 but also T2 will be affected by field strength and will generally be much shorter at 3.0 than 1.5 T [34], with a concomitant reduction in T2*. This will result in a slight reduction of SNR due to the long readouts usually employed in ASL (based on EPI or a ...
T1 and T2 The MP2RAGE78sequence was acquired for assessment of brain structure with a voxel resolution of 1 mm (isotropic). Resulting T1-weighted images and quantitative T1 maps can be used for analyses of gray and white matter (e.g., cortical thickness, voxel-based morphometry), as wel...
ears were observed across most intensities in tinnitus(+) and tinnitus(−) rats compared to controls. No significant differences, however, were found in plug-protected ears. For all graphs, error bars represent the standard error of the mean. * indicates specific significance (p < 0.05)...
(sagittal T1-, T2-weighted, short-tau inversion recovery (STIR), and axial T2*-weighted sequences) using a convolutional neural network (CNN)-based reconstruction which reduces the matrix size, oversampling rate, and number of excitations by applying a noise reduction algorithm. Scan quality was...
