目的:探讨经直肠超声造影(CEUS)和磁共振成像(MRI)诊断前列腺癌(PCa)有关问题,评价二者的诊断价值。方法:选取有完整相关临床资料的患者48例,对患者行前列腺超声造影及MRI检查,并与病理检查结果进行比较。结果:48例患者经病理检查证实为PCa 30例。经直肠CEUS诊断符合率为77.08%,敏感性为80.00%,与MRI的符合率(79.16%)、敏感性(76.67%)比较,差异无统计学意义(P>0.05),但其特异性(72.22%)低于MRI的特异性(83.33%),差异有统计学意义(P<0.05)。二者联合诊断的符合率为89.58%,敏感性为90.00%,特异性为88.89%,与单独一种诊断比较,差异均有统计学意义(P<0.05)。结论:经直肠CEUS及MRI对PCa的诊断各有优势,经直肠CEUS联合MRI可提高PCa的检出率。
Objective: To investigate the diagnostic value of transrectal ultrasound (CEUS) and magnetic resonance imaging (MRI) in the diagnosis of prostate cancer (PCa) and to evaluate their diagnostic value. Methods: Forty-eight patients with complete and relevant clinical data were selected. Ultrasonography and MRI were performed on the patients and compared with the pathological findings. Results: 48 patients confirmed by pathological examination for PCa 30 cases. The coincidence rate of rectal CEUS diagnosis was 77.08%, and the sensitivity was 80.00%. The coincidence rate with MRI (79.16%) and sensitivity (76.67%) showed no significant difference (P> 0.05) 72.22%) was lower than MRI specificity (83.33%), the difference was statistically significant (P <0.05). The coincidence rate of the two methods was 89.58%, the sensitivity was 90.00% and the specificity was 88.89%. There was significant difference between the two methods (P <0.05). Conclusion: The diagnosis of PCa by rectal CEUS and MRI has its own advantages. Rectal CEUS combined with MRI can improve the detection rate of PCa.
