[摘要] 目的 分析磁共振波谱成像诊断前列腺癌的价值。方法 方便选取该院2016年4月—2017年10月该院收治的的72例行磁共振波谱成像患者作为研究对象,经证实分为前列腺癌组和前列腺增生组,每组36例。对比两组患者的CC/C值,并分析磁共振波谱成像结果中前列腺癌的敏感度和特异度。结果 病理学诊断结果显示阳性38例,而磁共振波谱显示阳性36例,诊断敏感度为94.74%,特异度为89.47%。前列腺癌组患者CC/C值为(2.02±0.46),远高于前列腺增生患者CC/C值(0.75±0.13),对比差异有统计学意义(P<0.05)。结论 通过磁共振波谱成像方式诊断前列腺癌,能够保证其具有较高敏感度,特异度结果也比较理想,因此具有显著的临床价值。

[Abstract] Objective To analyze the value of MRS in diagnosis of prostatic carcinoma. Methods 72 cases of patients with MRS diagnosed in our hospital from April 2016 to October 2017 were convenient selected as the research objects and divided into two groups after confirmation, with 36 cases in each, and the CC/C value of the two groups was compared between the two groups, and the sensitivity and specificity of the MRS results were analyzed. Results The pathological diagnosis results showed that there were 38 positive cases, and the MRS showed that there were 36 positive cases, and the diagnosis sensitivity and specificity were respectively 94.74% and 89.47%, and the CC/C value in the prostatic carcinoma group was much higher than that in the hyperplasia of prostate gland group, [(2.02±0.46) vs (0.75±0.13)], and the difference between groups was statistically significant(P<0.05). Conclusion The MRS in diagnosis of prostatic carcinoma can ensure the higher sensitivity and the specificity results are ideal, therefore, it is of obvious clinical value.

前列腺癌是常見的中老年恶性肿瘤,传统上对于前列腺癌的诊断,临床主要采用通过直肠指诊或检查血清前列腺特异性抗原等方式开展,如果需要对疾病作进一步确诊,则主要通过直肠内超声检查的方式发现直肠指诊无法触及到的癌结节方式进行,也可以通过引导穿刺的方式进行活体检查[1]。但超声检查前列腺,其低回声信号不具有较明显的特异性,因此逐渐被磁共振波谱检查法替代[2]。目前在临床上,已经开始广泛通过磁共振波谱成像技术观察患者活体组织的代谢情况,并且此方法为无创诊断。该次研究方便选取该院2015年4月—2017年10月收治的72例行前列腺磁共振波谱成像患者进行回顾性分析,现报道如下。
