The phrase "attenuation inversion" is correct and usable in written English.
It can be used in contexts related to signal processing, telecommunications, or acoustics, where it describes a phenomenon involving the reversal of attenuation effects.
Example: "The study focused on the effects of attenuation inversion on signal clarity in urban environments."
Alternatives: "signal inversion" or "reversed attenuation".
Fluid attenuation inversion recovery.
The method is based on light attenuation inversion after processing a color space contraction using quaternions.
Thromboembolic infarcts usually manifest as a focal area of hyperintensity on T2-weighted and fluid attenuation inversion recovery (FLAIR) sequences in the involved region with diffusion restriction in acute stages (Fig. 1).
High-resolution three-dimensional T2 sequences, such as constructive interference steady state (CISS), fluid attenuation inversion recovery (FLAIR) and three-dimensional T1 sequences, are useful to depict the degree of parenchymal herniation [69].
T2-weighted fluid attenuation inversion recovery (FLAIR) scans of each subject were reviewed by a neuroradiologist (FB) to assess the presence of vascular lesions.
The fluid attenuation inversion recovery (FLAIR) MRI sequence provides cerebrospinal fluid-nulled, T2-weighted MRI images, on which oedema is hyperintense.
The results of four pre-infiltration attenuation inversions shows standard deviations below 0.1 Np/m, and demonstrate the consistency of the XBGPR tomography technique for making time-lapse observations.
Indeed, apparent diffusion coefficient (ADC) measurements, 66– 68 DWI values, 69 and fluid-attenuation inversion recovery images 70 correlate with the probability of response to therapy.
White matter hyperintensity (or leukoaraiosis) on fluid-attenuation inversion recovery MRI in elderly subjects is suspected to be a direct manifestation of microvascular ischaemic injury.
The detailed imaging parameters were as follows: 32-channel cardiac phased-array coil, TR/TE/FA = 3 matrix ms/10°, matrix 252 × 200, FOV 37.5 × 29.8 cm, SENSE factor 1.8, slice thickness = 3 mm, gap = −1.5 mm, linear k-space ordering, spectral attenuation with inversion recovery, acquired 133 sections, scan time 17.9 s, and breath-holding.
The PC fully compensates for the desired channel attenuations (channel inversion), so that P = β R α.
