MRI Stage Errors and incidence with a comparison of MRI stage to surgico-pathologic stage

T0(57 patients)

 Understaged (26:46%)T1b1: Tumor confined to the cervix or microscopic lesion greater than T1a1/a2, in greatest dimension (26)

T1b (139 patients)

 Understaged (18:13%)T2a1: Cervical carcinoma invades beyond uterus but not to pelvic wall or to lower third of vagina, ≤4 cm in greatest dimension (1)
T2a2: Cervical carcinoma invades beyond uterus but not to pelvic wall or to lower third of vagina > 4.0 cm in greatest dimension (1)
T2b: Tumor with parametrial invasion (16)

 Overstaged (3:2%)T0b1: After a positive biopsy for infiltrating carcinoma, no tumor was found in the cervix in the surgical specimen (3)

T2a (10 patients)

 Understaged (2:20%)T2b: Tumor with parametrial invasion (2)

 Overstaged (7:70%)T1b1: Tumor limited to cervix or microscopic lesion greater than T1a1/a2, ≤ 4.0 cm in greatest dimension (6)
T1b2: Tumor limited to cervix or microscopic lesion greater than T1a1/a2, > 4.0 cm in great dimension (1)

T2b (54 patients)

 Overstaged (25:46%)T1b1: Tumor limited to cervix, ≤ 4.0 cm or less in greatest dimension (11)
T1b2: Tumor limited to cervix, > 4.0 cm in great dimension (11)
T2a1: Cervical carcinoma invades beyond uterus but not to pelvic wall or to lower third of vagina, ≤4 cm in greatest dimension (3)
