Purpose To determine the linearity, bias, and precision of hepatic proton density fat fraction (PDFF)
measurements by using magnetic resonance (MR) imaging across different field …

… Acquired images are submitted electronically to Resonance Health’s data processing center
for image processing and pixel-by-pixel biexponential R2 fitting to generate R2 maps of the …

The use of sedation and general anesthesia has facilitated the significant growth of MRI use
among children over the last years. While sedation and general anesthesia are considered …

Management of pediatric chronic liver disease is limited by lack of validated noninvasive
biomarkers of histologic severity. We demonstrate that magnetic resonance elastography is …

… s, multiple free-hand ROI s, one large freehand ROI on a single section or all sections, to
ROI s … quite difficult to obtain large ROI s with circular ROI s, as the measureable regions are …

… For the current study, one reviewer drew all ROI s to minimize measurement dispersion
owing to this specific issue. Literature does exist, however, demonstrating excellent intra- and …

Rationale: Recent advancements that have been made in magnetic resonance imaging (MRI)
improve our ability to assess pulmonary structure and function in patients with cystic …

… for a TR = 2–4 s. Given some contribution of T1 weighting to parameter variability, we have
suggested a standardized repetition time TR = 4 s. Breathing mode did not reach consensus; …
