In cervical cancer, high resolution
are desired for determining loco-regional tumour spread.
This requires an increased SNR, which may be provided at
higher field strengths. Using external antennas combined
with an internal antenna, we demonstrate that the SNR at
7T can be increased with an additional factor 3.2.
Additionally, TSE visualization of the entire female
pelvis is achieved. The boosted SNR is used to obtain
MRI of the human cervix uteri and parametria, not only
showing a high level of details, but also alterations in
that enables distinguishing the cervix from the
