Nineteen pelvic MR and 21 CT examinations were performed in 21 patients with uterine cervical carcinoma. The results were compared with clinical (FIGO) staging in all patients, and with the histopathologic results after operation in 8. In the evaluation of local tumor growth CT agreed with clinical staging in 29%, MR imaging with clinical staging in 47% and CT with MR in 53%. The greatest discrepancy between the imaging methods and clinical examination was in the evaluation of parametrial extension. From 8 Stage I tumors with surgical confirmation the local tumor growth was overestimated with CT in 3 cases, with clinical examination in 2 and with MR imaging in 2 cases. CT and MR imaging at 0.02 T did not differ in the evaluation of parametrial tumor growth. Clinical examination overestimated parametrial growth but was relatively accurate in detecting vaginal wall involvement. MR imaging at 0.02 T is a convenient, inexpensive and accurate method for the local staging of early uterine cervical carcinoma.
对21例子宫颈癌患者进行了19次盆腔磁共振成像（MR）检查和21次计算机断层扫描（CT）检查。将结果与所有患者的临床（国际妇产科联盟，FIGO）分期进行比较，并与8例患者术后的组织病理学结果进行比较。在评估局部肿瘤生长方面，CT与临床分期的符合率为29%，MR成像与临床分期的符合率为47%，CT与MR的符合率为53%。成像方法与临床检查之间最大的差异在于对宫旁组织受累情况的评估。在经手术证实的8例I期肿瘤中，CT高估局部肿瘤生长3例，临床检查高估2例，MR成像高估2例。0.02T的CT和MR成像在评估宫旁肿瘤生长方面无差异。临床检查高估了宫旁组织生长，但在检测阴道壁受累方面相对准确。0.02T的MR成像是早期子宫颈癌局部分期的一种方便、廉价且准确的方法。
