Zusammenfassung
Purpose: Small particles of iron oxide (SPIO) are successful used as a contrast agent in liver MRI for lesion detection and characterization. The contrast effect is a result of the shortened T2 relaxation time due to the increased susceptibility of the iron particles. Susceptibility increases proportional with the magnetic field strength. Aim of the study was to analyse if the higher field strength at 3T compared to 1.5T translate into a higher contrast. Methods: An intra-individual comparative study on 22 consecutive patients (mean age 57 (34–73) m/f: 13/9) was performed on a 1.5T and a 3T Intera System (Philip…
