Comparative Study
The value of fast and ultrafast T2-weighted MR imaging sequences in hepatic enhancement with ferumoxides: comparison with conventional spin-echo sequence.
The efficacy of superparamagnetic iron oxide (SPIO) was evaluated with fast T2-weighted imaging sequences such as turbo spin-echo (TSE), half-Fourier single shot turbo spin echo (HASTE), and echo-planar imaging (EPI) in comparison with the conventional spin-echo (SE) sequence on a 1.5 Tesla MR unit. ⋯ Although TSE sequences and HASTE sequences are less susceptible to magnetic field inhomogeneities than SE and EPI sequences, the decrease in liver signal on HASTE and TSE sequences was comparable to that on EPI and SE sequences, respectively. These sequences are useful clinically for ferumoxides imaging, because they are less sensitive to motion artifacts.
