Incidence of staging errors.
| 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) |
