摘要
目的:对比分析电子计算机断层扫描(CT)、动态对比增强磁共振成像(DCE-MRI)及超声在卵巢癌诊断及临床分期中的价值。方法:选取在医院诊治的98例卵巢肿瘤患者,均行CT、DCE-MRI及超声检查,以术后病理检查为诊断标准,比较3种检查方法对卵巢癌及其临床分析的诊断价值。结果:CT和DCE-MRI诊断卵巢癌的准确率分别为87.76%和94.90%,明显高于超声诊断(70.41%),其差异有统计学意义(x^2=8.913,x^2=35.335;P<0.05);CT和DCE-MRI诊断卵巢癌的灵敏度分别为90.57%和98.11%,明显高于超声诊断(75.47%),其差异有统计学意义(x^2=4.283,x^2=11.851;P<0.05);CT和DCE-MRI诊断卵巢癌的特异度分别为84.44%和91.11%,明显高于超声诊断(64.44%),其差异有统计学意义(x^2=4.731,x^2=9.257;P<0.05);CT和DCE-MRI诊断卵巢癌的阳性预测值分别为87.27%和92.86%,明显高于超声诊断(71.43%),其差异有统计学意义(x^2=4.240,x^2=8.765;P<0.05);CT和DCE-MRI诊断卵巢癌的阴性预测值分别为88.37%和97.62%,明显高于超声诊断(69.05%),其差异有统计学意义(x^2=4.753,x^2=12.343;P<0.05)。CT、DCE-MRI诊断卵巢癌临床分期与术后病理检查结果比较差异无统计学意义;超声诊断卵巢癌临床分期Ⅱ期、Ⅲ期与术后病理检查结果比较差异有统计学意义(x^2=4.240,x^2=4.330;P<0.05)。结论:CT、DCE-MRI及超声在卵巢癌及其临床分期中均具有诊断价值,其中CT、DCE-MRI对卵巢癌及其临床分期的诊断性更高,两者联合诊断可提高卵巢癌及其临床分期的诊断准确性。
Objective:To compare and analyze the value of computed tomography(CT),dynamic contrast enhancedmagnetic resonance imaging(DCE-MRI)and ultrasound in the diagnosis and clinical staging of ovarian cancer.Methods:98 patients with ovarian tumor who received diagnosis and treatment in hospital were selected,and all of them underwent CT,DCE-MRI and ultrasound examinations.The postoperative pathological examination was used as diagnostic standard,and the diagnostic value of three examination methods and their clinical analysis on ovarian cancer were compared.Results:The accuracy rates of CT and DCE-MRI in diagnosing ovarian cancer were 87.76%and 94.90%,which were significantly higher than that of ultrasound(70.41%)(x^2=8.913,x^2=35.335,P<0.05),respectively.The sensitivities of CT and DCE-MRI in diagnosing ovarian cancer were 90.57%and 98.11%,which were significantly higher than 75.47%of ultrasound(x^2=4.283,x^2=11.851,P<0.05),respectively.The specificities of CT and DCE-MRI in diagnosing ovarian cancer were 84.44%and 91.11%,which were significantly higher than 64.44%of ultrasound(x^2=4.731,x^2=9.257,P<0.05),respectively.The positive predictive values of CT and DCE-MRI in diagnosing ovarian cancer were 87.27%and 92.86%,which were significantly higher than 71.43%of ultrasound(x^2=4.240,x^2=8.765,P<0.05),respectively.The negative predictive values of CT and DCE-MRI in diagnosing ovarian cancer were 88.37%and 97.62%,respectively,and they were significantly higher than 69.05%of ultrasound(x^2=4.753,x^2=12.343,P<0.05),respectively.There were no significant differences in diagnosing the clinical staging of ovarian cancer and the examination results of postoperative pathology between CT and DEC-MRI,respectively.The differences of stageⅡandⅢof clinical staging of diagnosing ovarian cancer between ultrasound and postoperative pathological examination were significant(x^2=4.240,x^2=4.330,P<0.05),respectively.Conclusion:CT,DCE-MRI and ultrasound have diagnostic value in ovarian cancer and its clinical staging.CT and DCE-MRI have more diagnostic value for ovarian cancer and its clinical staging,and the combined diagnosis of the two methods can improve the diagnostic accuracy of ovarian cancer and its clinical staging.
