【摘要】：目的:探讨常规MRI联合扩散加权成像(DWI)和动态增强(DCE)MRI在宫颈癌诊断及分期中的价值。方法:35例经手术病理或活检证实的宫颈癌患者按临床治疗方式分为手术组(20例)和非手术组(15例),以病理及临床分期为参照,评估常规MRI联合DWI、DCE-MRI(多模态MRI)对宫颈癌的分期诊断准确性。结果:手术组中常规MRI和多模态MRI对宫颈癌分期诊断符合率分别为80%(16/20)和95%(19/20)。术后病理证实盆腔淋巴结转移4例,MRI检出3例。非手术组中多模态MRI分期与临床分期符合率为67%(10/15)。结论:常规MRI联合DWI和DCE-MRI可提高对宫颈癌分期的准确性,有助于宫颈癌治疗方案的制定。
[Abstract]:Objective: to investigate the combination of conventional MRI with diffusion weighted imaging (DWI) and dynamic contrast enhancement (DCE). The value of MRI in the diagnosis and staging of cervical cancer. Methods 35 cases of cervical cancer confirmed by pathology or biopsy were divided into surgical group (n = 20) and non-operative group (n = 15). Routine MRI combined with DWI was evaluated by pathological and clinical staging. Results: the accuracy of staging diagnosis of cervical cancer by DCE-MRI (multimodal MRI). Results: the coincidence rate of conventional MRI and multimodal MRI in staging diagnosis of cervical cancer was 80% (P < 0.05). 16 / 20) and 95 / 20. Pelvic lymph node metastasis was confirmed by pathology in 4 cases. 3 cases were detected by MRI. The coincidence rate of multimodal MRI staging with clinical staging was 67 / 10 / 15 in non-operative group. Conclusion: routine MRI combined with DWI and DCE-MRI can improve the accuracy of cervical cancer staging. It is helpful to the development of cervical cancer treatment plan.
