超声、CT、MRI和血清CA125对卵巢癌诊断的对比分析

目的：分析卵巢癌的超声（US）、X线计算机体层摄影术（CT）和磁共振成像（MRI）及血清CA125水平的表现,评价这几种诊断方法在卵巢癌诊断中的价值。方法：36例卵巢癌患者术前同时行US、CT、MRI和血清CA125检查,结合手术结果、病理诊断与临床分期相对照分析。结果：US诊断准确率为72.2%,CT为86.1%,MRI为91.7%,CA125为69.5%。US可重复性高,对卵巢癌的早期检出率较高,但确诊率较低;CT和MRI对卵巢癌的确诊率较高,仍有漏误诊;血清CA125的确诊率也较低,可起到辅助诊断的作用。结论：US、CT、MRI和血清CA125具有各自的优势,合理的综合运用,可提高卵巢癌的早期诊断率,降低死亡率。

Study on the Advantages of Various Diagnostic Means (Ultrasound Sonography, CT, MRI and Serum CA125 Level Determination) for Ovarian Cancer

Objective To study the sensivitiy and accuracy of various diagnostic means （ultrasound sonography,CT,MRI,serum CA125 measurement） in patients with ovarian cancer.Methods The clinical results of these diagnostic means were retrospectively assessed in 36 patients with pathologically proven ovarian cancer.Results A definitive diagnosis was attainable in a higher percentage with CT （86.1% ） and MRI （91.7% ） ,while the result with sonography （72.2% ） ,or CA125 measurement （69.5% ） was lower.Conclusion Selectively combined examination with these four means would yield best diagnostic results in patients with ovarian cancer.
