Presentation of cervix carcinoma is often with small volume disease offering potential for fertility-sparing trachelectomy. Accurate preoperative depiction of tumor margins is crucial. The use of an endovaginal receiver coil has previously shown improvement in the detection of small tumors. At 3T EPI-DWI suffers disabling artefact and distortion with endovaginal coils. An alternative is Zoom-EPI (reduces distortion and improves resolution by reducing FOV). Purpose of study: Determine the sensitivity/specificity of T2-W + Zoom-DW imaging using an endovaginal coil at 3T for detecting cervical cancer, compare tumor:stromal contrast (T2-W vs. DWI) and document impact of the technique on surgical management.
