1、卵巢囊腺癌的MRI和CT诊断价值【摘要】目的 探讨MRI和CT对卵巢浆液性囊腺癌和黏液性囊腺癌的应用价值与选择。方法 回顾性分析22例MRI诊断卵巢囊腺癌经手术和病理证实的资料,结合CT对照分析。结果 MRI诊断14/22例为浆液性囊腺癌,8/22例为黏液性囊腺癌。病理13/14例为浆液性囊腺癌,1/14例为浆、黏液性囊腺瘤;5/8例为黏液性囊腺癌,3/8例为黏液性囊腺瘤。CT诊断10/20例为浆液性囊腺癌,10/20例为黏液性囊腺癌。病理9/10例为浆液性囊腺癌,1/10例为卵巢透明细胞癌;9/10例为黏液性囊腺癌,1/10例为浆液性囊腺癌伴出血
2、。MRI及CT均可显示卵巢囊腺癌为囊实性病变,即敏感性差异不大,在特异性方面前者在平扫时显示更为优越,但在增强后的特异性则后者又超过前者,原因是MRI在增强扫描时采用T1WI,此时黏液改变亦为高信号与显示的对比剂相混杂导致增强失真的效果,而CT增强扫描则可明确显示局部的不规则囊壁以及壁结节的形成。因此CT所显示的特异性更强,亦即对诊断的正确性更高。结论 浆液性囊腺癌MRI与CT应用价值相近,黏液性囊腺癌CT定性优于MRI。【关键词】卵巢囊腺癌磁共振成像体层摄影术X线计算机Thediagnosticvalueofovariancystadenocar
