In cervical cancer, high resolution T 2 images 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 high resolution T 2 -weighted MRI of the human cervix uteri and parametria, not only showing a high level of details, but also alterations in T 2 contrasts that enables distinguishing the cervix from the parametria.
