Pelvic MRI

A dedicated pelvic MRI protocol is recommended for optimal assessment.[1] MRI is considered superior to CT for local staging. Contrast enhanced MRI imaging improves accuracy in detecting myometrial invasion.

  • T1: hypo- to isointense to normal endometrium
  • T1 C+(Gd): carcinomatous tissue will enhance less than normal endometrium
  • T2: hyperintense or heterogeneous relative to normal endometrium

MR Imaging findings according to FIGO stage

  • stage 1a: tumour confined to the uterine endometrium
  • normal or widened endometrium
  • normal low T2 signal junctional zone
  • complete subendometrial enhancement on T1 contrast imaging
  • stage 1b: invasion of less than half of the myometrium
  • disruption or irregularity of the low T2 signal junctional zone
  • disruption of subendometrial early enhancement
  • stage 1c: invasion of outer half of myometrium
  • disruption or irregularity of the low T2 signal junctional zone
  • disruption of subendometrial early enhancement
  • preservation of band of outer myometrium
  • stage 2: tumour extends to cervix
  • stage 2a
  • widening of internal os and endocervical canal by high/isointense T2W signal tumour mass.
  • intact low T2W signal of normal cervical stroma
  • stage 2b
  • widening of internal os and endocervical canal by high/isointense T2W signal tumour mass
  • disruption of low T2 signal cervical stroma
  • stage 3: tumour extension beyond the uterus
  • stage 3a
  • irregularity to the uterine contour
  • disruption of low T2 signal uterine serosa
  • stage 3b
  • thickening of vaginal wall
  • high T2 signal tumour infiltrating low signal vaginal wall
  • stage 3c
  • pelvic/para aortic lymph node involvement
  • short axis >/= 8 mm in pelvic nodes
  • stage 4: bladder/rectal or distant metastasis
  • stage 4a
  • disruption of low T2 signal bladder or rectal wall
  • intraluminal bladder mass
