This study introduced a novel approach to differentiate
hypointense nodules on gadoxetic acid-enhanced
hepatobiliary phase images by use of a non-balanced
spin-echo SSFP (T2FFE) sequence. T2FFE typically
provides T2-weighted contrast, but theoretically has
high sensitivity to T1 shortening effects due to
gadoxetic acid. This approach might particularly be
useful for distinguishing metastases and hemangiomas.
