The use of MRI for cervical brachytherapy treatment
planning is growing in popularity but geometric
distortions from titanium applicators cause errors and
uncertainty for treatment planning. Phantom experiments
were performed to investigate sequence parameter
variants from a standard 2D T2w turbo spin echo
sequence. Quantitative measurements at the tip of the
applicator showed that changes to readout bandwidth,
even at the expense of increasing voxel size, can reduce
artifacts while maintaining SNR and a reasonable imaging
time.
