Functional liver imaging score (FLIS): A prognostic biomarker for acute-on-chronic liver failure and liver-related mortality

Sarah Poetter‐Lang, Lorenz Balcar, Ahmed Ba‐Ssalamah, Nina Bastati et autres

BACKGROUND & AIMS: The functional liver imaging score (FLIS; range 0-6, with higher scores indicating better liver function), derived from gadoxetic acid-enhanced MRI, is a prognostic imaging biomarker in advanced chronic liver disease (ACLD). Our aim was to investigate whether semi-quantitative FLIS …

Disease severity prognostication in primary sclerosing cholangitis: a validation of the Anali scores and comparison with the potential functional stricture

Sarah Poetter‐Lang, Ahmed Ba‐Ssalamah, Alina Messner, Nina Bastati et autres

Abstract Objectives Our aim was twofold. First, to validate Anali scores with and without gadolinium (ANALIGd and ANALINoGd) in primary sclerosing cholangitis (PSC) patients. Second, to compare the ANALIs prognostic ability with the recently-proposed potential functional stricture (PFS). Materials and methods This …

Are dilution, slow injection and care bolus technique the causal solution to mitigating arterial-phase artifacts on gadoxetic acid–enhanced MRI? A large-cohort study

Sarah Poetter‐Lang, Raphael Ambros, Alina Messner, Antonia Kristic et autres

OBJECTIVE: Arterial-phase artifacts are gadoxetic acid (GA)-enhanced MRI's major drawback, ranging from 5 to 39%. We evaluate the effect of dilution and slow injection of GA using automated fluoroscopic triggering on liver MRI arterial-phase (AP) acquisition timing, artifact frequency, and lesion visibility. …

Metabolic tumor volume and sites of organ involvement predict outcome in NSCLC immune-checkpoint inhibitor therapy

Daria Kifjak, Maximilian J. Hochmair, Daniel Sobotka, Alexander Haug et autres

Purpose The purpose of this study was to assess the ability of pretreatment PET parameters and peripheral blood biomarkers to predict progression-free survival (PFS) and overall survival (OS) in NSCLC patients treated with ICIT. Methods We prospectively included 87 patients in this …

Diagnosis of functional strictures in patients with primary sclerosing cholangitis using hepatobiliary contrast-enhanced MRI: a proof-of-concept study

Sarah Poetter‐Lang, Alina Messner, Nina Bastati, Kristina I. Ringe et autres

OBJECTIVES: PSC strictures are routinely diagnosed on T2-MRCP as dominant- (DS) or high-grade stricture (HGS). However, high inter-observer variability limits their utility. We introduce the "potential functional stricture" (PFS) on T1-weighted hepatobiliary-phase images of gadoxetic acid-enhanced MR cholangiography (T1-MRC) to assess inter-reader …

Influence of dilution on arterial-phase artifacts and signal intensity on gadoxetic acid–enhanced liver MRI

Sarah Poetter‐Lang, Gregor Dovjak, Alina Messner, Raphael Ambros et autres

Abstract Objectives To investigate the effect of saline-diluted gadoxetic acid, done for arterial-phase (AP) artifact reduction, on signal intensity (SI), and hence focal lesion conspicuity on MR imaging. Methods We retrospectively examined 112 patients who each had at least two serial gadoxetic …

Gadoxetic acid-enhanced MRI-derived functional liver imaging score (FLIS) and spleen diameter predict outcomes in ACLD

Nina Bastati, Lucian Beer, Ahmed Ba‐Ssalamah, Sarah Poetter‐Lang et autres

BACKGROUND & AIMS: Functional liver imaging score (FLIS) - derived from gadoxetic acid-enhanced MRI - correlates with liver function and independently predicts liver-related mortality in patients with chronic liver disease (CLD), while splenic craniocaudal diameter (SCCD) is a marker of portal hypertension. …
