In the present article, interactions associated with magnetic resonance (MR) procedures and MR test procedures for implants/devices are examined.#Since 2012, many interactions of items with MR procedures have been physically described and translated into standardized ASTM and ISO testing procedures. Desp...
From the crystal symmetry, the anisotropy is considered to be uniaxial, then the spin Hamiltonian is described simply as (6)H=gμBHZSZ+DSZ2. The energy diagram as a function of applied magnetic field is shown in Fig. 10. The observed absorption is identified as the transition indicated ...
These may include infiltrative cardiomyopathies, such as amyloidosis, or diffuse myocardial fibrosis from any of multiple causes, resulting in reduced specificity for acute inflammation (a similar limitation described for the EGE technique). There is evidence that T2 mapping may be more specific for...
The technique is described in detail, and results for five different approximations of the He target state are presented in a table. Good convergence is obtained, but it is found that even the best calculated value of the resonance is about 130 meV higher than the experimentally measured value...
However, note that our metasurface design differs from what is usually called “metamaterial lens”. The smart metasurface’s functionality might be best described in terms of a local resonant structure (composed of an array of wire-shaped unit cells) exited by the Rx field, which inductively ...
The univariate forest plot of diagnostic performance (in ln OR) showed considerable overlap in CIs between studies with different ORs, indicating that heterogeneity might be caused by sample variance (see Fig.3)23. As described in the study description above, inter-study differences were present in...

Zink's Common Compensatory Pattern (CCP) is a pattern of somatic dysfunction that can be observed in the spinal transitional zones. The CCP can be described as left/right/left/right rotation in the regions of C0/C1/C2, C7/T1, T12/L1, and... J Sánchez,J Brohard,R Thai - 《Aao Jou...
The paper is organized as follows. In “Gaussian approximation in cumulant expansion” we recall the Gaussian approximation in cumulant expansion, where the assumptions of Gaussianity and stationarity of increments of the stochastic processes are clearly formulated. Moreover, by applying the PFG sequence...
Diffusion is typically restricted in tissue, with the level of restriction depending on the microstructure and diffusional properties of the endothelium. The level of restriction can be described as the ADC. The physiological details of restricted diffusion and how they affect such measurements are desc...
