目的:对CT与MRI在前列腺癌疾病诊断应用中的效果进行对比分析与研究。方法:选取30例前列腺癌患者,其临床病症表现为尿痛、尿频、尿不尽、尿急等,均行MRI常规性扫描、CT增强性的双期动态扫描、CT增强与平行扫描。利用统计学理论知识对两组患者的图像数据与诊断结果进行对比观察与分析。结果:A期前列腺癌2例,B期前列腺癌7例,C期前列腺癌10例,D期前列腺癌11例。9例A期或B期前列腺癌患者,经CT增强或平行扫描后直接确诊者4例,而MRI平行扫描后直接确诊者7例。21例C期或D期前列腺癌患者,MRI平扫后直接确诊者20例,而CT增强或平行扫描后直接确诊者18例。结论:MRI对A期或B期的前列腺癌患者的诊断准确率高于CT,而MRI与CT对C期或D期的前列腺癌患者的诊断准确率之间无明显差异。
Objective: To compare and analyze the effect of CT and MRI in the diagnosis of prostate cancer. Methods: Thirty patients with prostate cancer were selected. The clinical manifestations included dysuria, frequent urination, urinary incontinence, urinary urgency, etc. All patients underwent conventional MRI, CT enhanced double - phase dynamic scanning, CT enhancement and parallel scan. The use of statistical theory of knowledge of the two groups of patients with image data and diagnostic results were observed and compared. Results: There were 2 cases of stage A prostate cancer, 7 cases of stage B prostate cancer, 10 cases of stage C prostate cancer and 11 cases of stage D prostate cancer. Nine patients with stage A or B prostate cancer were directly diagnosed by CT enhancement or parallel scan in 4 cases, while 7 cases were directly diagnosed by MRI parallel scan. Twenty-one patients with stage C or D prostate cancer were diagnosed directly by MRI in 20 cases, while 18 cases were diagnosed directly by CT enhancement or parallel scan. Conclusion: The diagnostic accuracy rate of MRI for stage A or B prostate cancer patients is higher than that of CT, while there is no significant difference between MRI and CT for the diagnosis of prostate cancer stage C or D patients.
