Extending MRI to the Quantification of Turbulence - DiVA

The ability to characterize intralesional fat is further expanded by the ability of magnetic resonance imaging to detect small quantities (intravoxel) of fat. type-2 chemical-shift artifact as intravoxel fat, and we refer to areas of fat signal that are un- perturbed on opposed-phase images as gross fat, recognizing that both are intracellular. Subjective detection of intravoxel fat on opposed-phase and in-phase GRE images did not correlate with the diagnosis of minimal fat AML . Although none of the minimal fat AMLs demonstrated cystic degeneration or necrosis, up to 36% (33 of 88) and 39% (34 of 88) of clear cell RCCs demonstrated cystic degeneration or necrosis ( P < .001) ( Fig 4 ). intravoxel lipid and can be used to make definitive benign diagno- ses, characterize the tissue composition of solid organs, and serve as an adjunct imaging feature aiding in the diagnosis of a variety Liver intravoxel incoherent motion diffusion-weighted imaging for the assessment of hepatic steatosis and fibrosis in children World J Gastroenterol . 2018 Jul 21;24(27):3013-3020.

others) - "Diffusion-weighted MRI: influence of intravoxel fat signal and breast density on breast tumor conspicuity and apparent diffusion coefficient measurements." Spearman's correlation coefficient was used to evaluate the correlation between each fatty acid (e.g., total lipid (TL), total saturated fatty acid (TSFA), total unsaturated fatty acid (TUSFA), total unsaturated bond (TUSB), and polyunsaturated bond (PUSB)) and intravoxel incoherent motion (IVIM) mapping images (e.g., Dtrue, Dfast, and Pfraction). ADC values for tumor and normal tissue were significantly lower when fat suppression was not used (Pb.0001 for both), while no differences were observed for the water phantom (P=.17). - "Diffusion-weighted MRI: influence of intravoxel fat signal and breast density on breast tumor conspicuity and apparent diffusion coefficient measurements." Bisect kidney through renal hilus and surrounding perinephric fat. Identify and measure adrenal, if present.

2014-11-01 · The fat-suppressed diffusion decay from an ROI in the vertebral bone marrow (L1) and from an ROI in the noise are shown. As indicated by the curvature of the decay on the semi-log plot, the diffusion signal in bone marrow displays a bi-exponential behavior with a fast-decaying component for b -values between 0 and 100 s/mm 2 and a slow-decaying component for b -values between 100 and 600 s/mm 2 . Fat accumulates as droplets in the hepatocyte swelling, distortion of microcirculatory anatomy and compression of sinus. This study aims to investigate the correlation between the T2*-corrected fat fraction (FF) value acquired via gradient echo with a low flip angle and parenchymal pseudorandom blood perfusion (P fraction), microcirculation (D fast), and slow component of diffusion (D slow 2015-10-13 · Purpose To prospectively evaluate the changes in fatty acid concentration after administrating a 60% high-fat diet to a non-alcoholic fatty liver disease rat model and to perform a correlation analysis between fatty acid with molecular diffusion (D true ), perfusion-related diffusion (D fast ), and perfusion fraction (P fraction ). Material and Methods This prospective study was approved by 2019-06-18 · Chemical shift imaging techniques such as Dixon or IDEAL MRI allow for intravoxel quantification of fat, and may be more sensitive to changes in the muscle fat content [43, 44].

Identify and measure tumor (3 dimensions) and distance to the following margins: external (Gerota’s fascia or fat), renal vasculature, ureter. The presence of macroscopic fat makes them easy to recognize on CT or MRI. Attenuation on nonenhanced CT will be well below 0 HU. At MR imaging the fatty portions will be hyperintense on non fat-saturated T1-weighted images and show signal dropout on fat-saturated T1 or T2-weighted images. Calcifications are seen in approximately 24% of cases.

In this study, we assessed the influence of intravoxel fat signal on breast diffusion measures by comparing ADC values obtained using a diffusion-weighted single shot fast spin-echo sequence with and without fat suppression.
