T1 corrected multipeak T2*-IDEAL gradient-echo imaging for the quantification of intermuscular adipose tissue
Introduction: Intermuscular adipose tissue (IMAT) has been recently associated with different metabolic abnormalities including obesity and insulin resistance [1]. The distribution and the total amount of IMAT have been traditionally assessed using T1-weighted imaging [1]. However, quantification of IMAT based on T1-weighted imaging is limited by partial volume effects and requires effective se...
متن کاملHigh SNR Acquisitions Improve the Repeatability of Liver Fat Quantification Using Confounder-corrected Chemical Shift-encoded MR Imaging
PURPOSE To determine whether high signal-to-noise ratio (SNR) acquisitions improve the repeatability of liver proton density fat fraction (PDFF) measurements using confounder-corrected chemical shift-encoded magnetic resonance (MR) imaging (CSE-MRI). MATERIALS AND METHODS Eleven fat-water phantoms were scanned with 8 different protocols with varying SNR. After repositioning the phantoms, the ...
متن کاملPredicting Hepatic Steatosis in Living Liver Donors via Noninvasive Methods
Hepatic steatosis assessment is of paramount importance for living liver donor selection because significant hepatic steatosis can affect the postoperative outcome of recipients and the safety of the donor. The validity of various noninvasive imaging methods to assess hepatic steatosis remains controversial. The purpose of our study is to investigate the association between noninvasive imaging ...
متن کاملQuantification of Single-Kidney Function and Volume in Living Kidney Donors Using Dynamic Contrast-Enhanced MRI.
OBJECTIVE The objective of our study was to investigate whether dynamic contrast-enhanced MRI (DCE-MRI) can detect differences and potential adaption in single-kidney parenchymal volume, blood flow, glomerular filtration rate (GFR), and filtration fraction in the remaining kidney of healthy donors compared with nondonors. Further, we evaluated the agreement in donor GFRs measured using DCE-MRI ...
متن کاملHeterogeneous living donor hepatic fat distribution on MRI chemical shift imaging
PURPOSE We evaluated the heterogeneity of steatosis in living donor livers to determine its regional differences. METHODS Between June 2011 and February 2012, 81 liver donors were selected. Fat fraction was estimated using magnetic resonance triple-echo chemical shifting gradient imaging in 13 different regions: segment 1 (S1), S2, S3, and each peripheral and deep region of S4, S5, S6, S7, an...
