ESGO ESTRO ESP cervical cancer imaging MRI CT staging guideline

MRI pelvis is the best scan for suspected cervical carcinoma when assessing the primary tumor and local staging.
  • MRI pelvis with diffusion-weighted sequences best shows tumor size, stromal invasion, parametrial involvement, vaginal/uterine extension, and relation to bladder or rectum. This guides surgery versus chemoradiotherapy. ESGO cervical-cancer guideline recommends pelvic MRI for initial assessment of pelvic tumor extent.
  • CT chest, abdomen, and pelvis is less accurate for the cervical tumor itself, but useful to assess enlarged lymph nodes, lungs, liver, hydronephrosis, and distant spread.
  • For locally advanced cancer or suspicious nodes, FDG PET-CT is generally preferred over CT alone for nodal and distant metastatic staging, especially before curative chemoradiation. Imaging guideline review
  • Imaging does not confirm the diagnosis. Diagnosis requires pelvic examination plus colposcopy-directed cervical biopsy.
Practical answer: Order MRI pelvis for local staging, then add PET-CT or contrast CT chest/abdomen/pelvis if advanced disease or nodal/distant spread is suspected. In pregnancy, MRI without gadolinium is preferred.
