Abstract
The purpose of the present prospective study was, to determine the efficacy of MRI in predicting extracervical tumour invasion on the basis of the presence of a very thin (< 3 mm) univolved cervical stromal ring. Forty-seven consecutive patients with uterine cervical carcinoma (FIGO stages Ib–IIa) were examined with axial and sagittal T2-weighted MRI sequences. Pathological proof after hysterectomy was obtained in all women. On he basis of the MRI visualisation of a thinned stroma (<3 mm), the sensitiivity in predicting extracervical involvement was 94.1% and the specificity 73.3% (accuracy 80.85%). On the basis A the detection of complete stromal disruption the MRI sensitivity ill predicting extracervical involvement was 76.5% and specificity 93.3% (accuracy 87.23%). The results of our study indicate that in the interpretation of MRI findings, the visualisation of an uninvolved cervical stromal ring at least 3 min thick can predict the presence of extracervical tumour with very high sensitivity.
