Thirty-seven patients with carcinoma of the cervix were prospectively staged by examination under anaesthesia (EUA), transvaginal and transrectal ultrasound, computed tomography (CT) and magnetic resonance imaging (MRI). Pathological correlation was available for 20 patients. In the pathologically staged patients, EUA agreed with the staging in 17, understaging three patients. Endosonography agreed with the staging in 19, CT in 16 and MRI in 18 patients. For the remaining 17 patients, endosonography agreed with the EUA findings in 13, CT in 12 and MRI in 12. This study has shown that endosonography and MRI are more accurate than CT in the local staging of carcinoma of the cervix. Computed tomography was least accurate in staging early tumours and differentiating between Stage Ib and IIb disease. Lymph node involvement was detected with equal frequency by both CT and MRI. Magnetic resonance imaging was useful in identifying vaginal and bladder wall involvement and in one patient showed features due to an unsuspected early pregnancy.
对37例宫颈癌患者通过麻醉下检查（EUA）、经阴道和经直肠超声、计算机断层扫描（CT）以及磁共振成像（MRI）进行前瞻性分期。20例患者有病理对照。在经病理分期的患者中，EUA与分期相符的有17例，3例分期过低。腔内超声与分期相符的有19例，CT为16例，MRI为18例。对于其余17例患者，腔内超声与EUA检查结果相符的有13例，CT为12例，MRI为12例。本研究表明，在宫颈癌的局部分期中，腔内超声和MRI比CT更准确。CT在早期肿瘤分期以及区分Ib期和IIb期疾病方面准确性最低。CT和MRI检测淋巴结受累的频率相同。磁共振成像有助于识别阴道和膀胱壁受累情况，在1例患者中显示出意外早期妊娠的特征。
