摘要 目的探究CT、MRI不同扫描方法对垂体微腺瘤的应用价值。方法回顾性收集经我院临床诊断的垂体微腺瘤61例,女57例,男3例,平均年龄32.66±7.88岁。61例均经MRI平扫及增强检查(常规增强15例、动态增强46例),其中35例行CT检查(平扫26例、增强15例)。分析垂体微腺瘤直接征象与间接征象,采用McNemar检验对比分析不同扫描方法的价值。结果MRI平扫垂体微腺瘤显示率62.30%(38/61),常规增强显示率40.00%(6/15),动态增强显示率93.48%(43/46);CT平扫显示率15.38%(4/26),CT增强显示率33.33%(5/15)。26例均行CT平扫、MRI平扫、MRI动态增强检查,CT平扫与MRI平扫、CT平扫与MRI动态增强之间诊断结果的差异均有统计学意义(P=0.016,P=0.000);15例均行CT增强、MRI动态增强,两者之间诊断结果的差异有统计学意义(P=0.004);15例均行MRI平扫、MRI常规增强,两者之间诊断结果的差异无统计学意义(P=0.5);46例均行MRI平扫、MRI动态增强,两者之间诊断结果的差异有统计学意义(P=0.000)。结论MRI平扫结合动态增强有利于垂体微腺瘤的显示,该方法可作为常规检查技术应用于临床。 Objective To study the value of different scanning methods of CT and MRI for pituitary microadenomas.Methods A retrospective collection of 61 patients with clinically diagnosed pituitary microadenomas,57 females and 3 males,with a mean age of(32.66±7.88)years were collected from our hospital.All 61 cases underwent MR plain and enhanced scans(15 conventional enhancement,46 dynamic enhancement),of which 35 cases underwent CT scans(26 plain,15 enhanced).Direct and indirect signs of pituitary microadenomas were analysed and a comparative analysis of the value of different scanning methods using the McNemar test was performed.Results The display rate of pituitary microadenoma was 62.30%(38/61)for MRI plain scan,40.00%(6/15)for conventional enhancement and 93.48%(43/46)for dynamic enhancement;the display rate of pituitary microadenoma was 15.38%(4/26)for CT plain scan and 33.33%(5/15)for CT enhancement.CT plain scan,MRI plain scan,and MRI dynamic enhancement were performed in 26 cases,and the differences in diagnostic results between CT plain scan and MRI plain scan,and between CT plain scan and MRI dynamic enhancement were statistically significant(P=0.016,P=0.000).CT enhancement and MRI dynamic enhancement were performed in all 15 cases,and the difference between the two diagnostic results was statistically significant(P=0.004).MRI plain and MRI conventional enhancement were performed in 15 cases,and the difference between the two diagnostic results was not statistically significant(P=0.5).MRI plain and MRI dynamic enhancement were performed in all 46 cases,and the difference between the two diagnoses was statistically significant(P=0.000).Conclusion Magnetic resonance plain scanning combined with dynamic enhancement helps to show pituitary microadenomas,and this method can be used as a routine clinical screening technique.
