T2-w imaging (coronal and axial TrueFISP, coronal HASTE)
of 12 healthy volunteers was evaluated qualitatively and
quantitatively at 7 Tesla and 1.5 Tesla. MR images of
the small bowel at 7T can be generated with an image
quality that is sufficient for routine diagnostics.
Despite an increasing number of artifacts at 7T, tissue
contrast and image quality were equivalent as compared
with those achieved with 1.5T.
