<h3>BACKGROUND AND PURPOSE:</h3> Synthetic MR imaging enables the creation of various contrast-weighted images including double inversion recovery and phase-sensitive from a single quantification scan. Here, we assessed whether synthetic is suitable for detecting MS plaques. <h3>MATERIALS METHODS:</h3> Quantitative conventional data on 12 patients with were retrospectively analyzed. T2-weighted, FLAIR, recovery, produced after T1 T2 values proton density. Double optimized each patient by...
<h3>BACKGROUND AND PURPOSE:</h3> T1 and T2 values proton density can now be quantified on the basis of a single MR acquisition. The myelin edema in voxel also estimated from these values. purpose this study was to evaluate multiparametric quantitative imaging model that assesses for characterizing plaques, periplaque white matter, normal-appearing matter patients with MS. <h3>MATERIALS METHODS:</h3> We examined 3T data 21 partial volume, excess parenchymal water inverse transverse relaxation...
Background Liver MR fingerprinting (MRF) enables simultaneous quantification of T1, T2, T2*, and proton density fat fraction (PDFF) maps in single breath-hold acquisitions. Histopathologic correlation studies are desired for its clinical use. Purpose To compare liver MRF-derived metrics with separate reference quantitative MRI participants diffuse disease, evaluate scan-rescan repeatability MRF, validate measurements histologic grading biopsies. Materials Methods This prospective study...
Purpose To evaluate the feasibility of liver MR fingerprinting (MRF) for quantitative characterization and diagnosis focal lesions. Materials Methods This single-site, prospective study included 89 participants (mean age, 62 years ± 15 [SD]; 45 women, 44 men) with various lesions who underwent MRI between October 2021 August 2022. The routine clinical MRI, non-contrast-enhanced MRF, reference a 1.5-T scanner. bias repeatability MRF measurements were assessed using linear regression,...
Objective and contrast-free methods for differentiating benign focal liver lesions from malignant (e.g., hepatocellular carcinomas metastases) are desired. Herein, we evaluated the diagnostic capability of magnetic resonance fingerprinting (MRF) in patients with lesions. Liver MRF provided repeatable T1, T2, T2*, fat-fraction values various The T1 T2 relaxation times showed high agreement separate conventional quantitative mapping measurements. Measurements a combination good differentiation...
Magnetic resonance fingerprinting (MRF) has been proposed for simultaneous T1, T2, T2*, and fat-fraction mapping of the liver, which is suitable diagnosis monitoring liver diseases. We evaluated repeatability MRF measurements correlated it with reference standard imaging in patients diffuse disease. Furthermore, we validated MRF-derived against histological grading biopsies. Liver provided repeatable multi-parametric maps high agreement separate conventional quantitative as well This...
Synthetic MRI using two types of scan data, namely MP2RAGE and Multi TE, calculates T1 value T2 by relaxation time analysis a Bayesian estimation method. Making use the NIST phantom quantitative as true value, we examined influence setting conditions on MP2RAGE, which is an index that multi indicator value.
