摘要
目的研究CT和MRI对前列腺癌的临床诊断价值,为提高临床诊断率提供理论依据。方法选择对比研究的方式对2013年12月-2014年12月70例前列腺癌患者展开研究,所有患者均行CT检查(对照组)和MRI检查(研究组),并以病理组织诊断结果为标准对两种检查方式进行优劣的比较。结果以病理活检为标准,在前列腺癌A期和B期患者的诊断中,两组患者在诊断相符率、误诊率及漏诊率的比较上χ2=40.17、17.69、12.99,P<0.05,具有明显统计学差异;在前列腺癌C期和D期患者的诊断中,两组患者无明显差异。结论MRI对前列腺癌的诊断准确率高,可作为对患者进行分期评估的临床辅助检查方式进行推广;CT对前列腺癌患者的A期和B期诊断率低,仅在C期和D期的诊断中具有较高的准确率,因此不建议在早期前列腺癌的诊断中使用。
Objective This paper is to investigate clinical value of CT and MRI in diagnosis of prostate cancer, and to provide theoretical basis for improving clinical diagnostic rate. Methods The method of comparative study was applied to conduct investigation on 70 patients with prostate cancer from December, 2013 to December, 2014, all patients underwet CT examination（control group） and MRI（research group）, and advantages and disadvantages of two types of inspection method were compared on the basis of histopathologic diagnosis. Results The comparisons in consistent diagnosis rate, misdiagnosis rate and the rate of missed diagnosis of patients in two groups in the diagnosis of prostate cancer of patients at Stage A and Stage B on the basis of pathological biopsy satisfied χ2=40.17, 17.69 and 12.99（P〈0.05） respectively, the differences were significantly statistical, and there was no difference between the two groups of patients in the diagnosis of patients with prostate cancer at stage C and D. Conclusions MRI delivers high accuracy in the diagnosis of prostate cancer, and it can be used and promoted in auxiliary examination of clinical evaluation on patients in stages way, CT casts diagnostic rate of patients with prostate cancer at Stage A and Stage B, and high accuracy is only founded in the diagnosis at Stage C and Stage D, therefore it is not recommended to be used in the diagnosis of early prostate cancer.
