Zusammenfassung:Highlights • Signal intensity is often used to evaluate hepatic enhancement with Gd-EOB-DTPA in the hepatobiliary phase. • Comparison of uncorrected signal intensity with T1 value revealed signal intensity instability. • Measurement of uncorrected liver SI or SNR often yields erroneous results on late-phase gadoxetate MRI due to shimming and other optimization techniques. • Signal intensity corrected by scale and rescale slope from DICOM data gave comparable results.
