摘　　要：目的:探讨早期宫颈癌3.0 T高场强磁共振成像(MRI)术前评估的临床应用价值。方法:回顾性分析我院20例经手术证实的早期宫颈癌(临床分期为Ⅰb和Ⅱa期)的3.0 T高场强MRI影像资料,并将其与术后病理结果对照,分析3.0 T高场强MRI对早期宫颈癌术前评估的准确率。结果:早期宫颈癌表现为宫颈部实性肿物T1WI低信号14例(14/18)、T_2WI高信号10例(10/18),15例(15/18)肿瘤病灶比正常宫颈肌层强化时间早(4±2.1)s,13例(13/18)肿瘤病灶时间-信号曲线(TIC)呈快速上升-缓慢下降型,术前评估分期准确率约为88.3%。结论:3.0 T高场强MRI对早期宫颈癌的诊断具有明显的临床应用价值,为选择最佳治疗方案提供参考。Objective： To investigate the diagnostic value of 3.0 T MRI in preoperatively evaluation with early-stage cervical carcinoma. Methods： 20 patients with pathologically-confirmed early-stage cervical carcinoma were enrolled in this study. Both preoperative evaluation of 3.0 T MRI and clinical pathologic were performed in all the patients. The rates of diagnostic by 3.0 T MRI were statistically analyzed. Results： The preoperative MRI staging accuracy was 88.3%. The imaging of the tumor showed solid tumor with high intensity signal on T2 WI（10/18） and low intensity signal On T1 WI（14/18）. In all patients, the tumers of 15 cases were earlier（4 ± 2.1） s than myometrium. The time signal intensity curves of 13 cases were rapidly rised-slowly down. Conclusion： 3.0 T MRI has key value for early cervical cancer preoperation. It can help us to completely understand the situation of early stage cervical cancer and select the suitable treatment plan.
