摘要
目的研究对宫颈癌宫旁浸润的CT灌注判别函数,用于提高宫颈癌宫旁浸润CT灌注诊断的准确性。方法选取我科100例术后经病理确诊为宫颈癌的患者,根据病理结果分为宫旁浸润组和非宫旁浸润组。所有患者术前均行64层螺旋CT灌注扫描,分别利用CT形态学和CT灌注判别参数对于宫旁浸润进行诊断,对比其灵敏度和特异度。结果宫旁浸润组的BV、BF和PBV均显著高于非宫旁浸润组,TTP、TTS、Permeability均显著低于非宫旁浸润组,P<0.01。结论宫颈癌宫旁浸润的CT灌注判别函数术前诊断可提高对于宫旁浸润诊断的灵敏度和特异度。
Objective To study on cervical parametrial invasion of CT perfusion discriminant function in improving accuracy of CT perfusion for the diagnosis of cervical parametrial invasion. Methods From nay families and 100 cases patients with postoperative pathological diagnosis of cervical cancer, according to the result of pathology by infiltrating into palace group and non palace by infiltration.All patients with preoperative spiral CT perfusion scanning line 64 layer, respectively, using morphological and CT perfusion CT discriminant parameter for invasive diagnosis palace, contrast sensitivity and specific degrees.Results The palace by infiltrating group BV, BF and PBV invasive group were significantly higher than that of the palace, TTP, TTS, Pemaeability invasive group were significantly lower than the palace, P 〈 0.01）. Conclusion CT perfusion parametrial invasion of cervical cancer diagnosis discriminant function before surgery can improve the sensitivity for the diagnosis ofparametrial invasion and specificity.
