Conclusion
This study demonstrates a significant positive effect on pelvic MRI image quality of the intravenous administration of antispasmodic drug,
suggesting that its use is still the best technique to reduce motion artifacts and improve image quality,
with an obvious preference as the sequence of choice for the radiologists.
Despite the fact that the T2-TSE-BLADE sequence shows fewer artifacts,
caused by the elimination of the ghosting artifacts (fig.
5),
the uterine layer differentiation and global quality was approximately equal to a standard T2-TSE.
In summary,
BLADE technique cannot replace the overall superior quality of a T2-TSE sequence after the intravenous administration of an antispasmodic drug,
but can be possibly used as an alternative to patients with some contra-indications to the use of these drugs.
This study could possibly be improved with the inclusion of a larger number of cases in order to give increase its statistical power.
The inter-observer agreement is moderated,
and good on uterine anatomy differentiation and preferred sequence.
Other techniques can eventually be used in future projects,
such as the pelvic band compression,
other phase-encoding directions and a spatial saturation pulse (useful to eliminate the ghosting artifact).
