A comparative study of computerized tomography, magnetic resonance imaging, and clinical staging for the detection of early cervix cancer.

Sixteen patients with cervical cancer underwent radical surgery following standard clinical staging, MRI, and CT. The sensitivity of the CT scan was 14%, the specificity 100%. MRI had a sensitivity of 28% and a specificity of 64%. The clinical stage was correct in 10 of 16 patients (62%). CT and MRI are not individually or collectively better than clinical staging in predicting extent of disease, and currently should not be included in the FIGO staging for cervix cancer.
