Abstract
However, more clinical evidence is needed to determine which
method or combination of methods achieves the best accuracy for
assessment of fibrosis, fat, and iron deposition. In phase and
opposed phase MR imaging allows reliable detection of focal
steatosis hepatis owing to the chemical shift cancellation artifact.
Areas of steatosis demonstrate signal loss on opposed phase images.
In addition, T2* effects allow reliable detection of iron storage
diseases related susceptibility artifacts. Areas of iron storage
demonstrate pronounced signal loss on the image with the longer
echo time. MR spectroscopy has potential tool utility for assessment
of metabolic function, particularly with respect to liver fat
quantification. It also may provide useful information about other
aspects of diffuse liver disease (eg, inflammation and fibrosis).
However, in vivo application of MR spectroscopy in the abdomen
and pelvis is limited by spectral resolution, SNR, and motion. In
summary, MR spectroscopy of the liver is a novel evolving
technology with the potential to improve tissue characterization
when used in conjunction with other conventional MR sequences.
