摘  要:目的  研究分析对肝脏孤立性结节鉴别诊断中使用MRI和CT的价值。方法  2019年1月~2020年9月,选取枣庄市肿瘤医院的122例疑似肝脏孤立性结节患者。运用随机数表法随机分为研究组和对照组,研究组61例用MRI,对照组61例用CT,以手术病理结果作为金标准。分析肝脏孤立性结节的检出率和阳性率,以及灵敏度和特异性。结果  122例经过手术病理均确诊为97例为肝脏孤立性结节,研究组50例,对照组47例。研究组肝脏孤立性结节的检出准确率高于对照组,差异有统计学意义(P<0.05),研究组灵敏度和特异性高于对照组(P<0.05)。结论  对肝脏孤立性结节鉴别诊断中使用MRI,准确率高,并且灵敏度和特异性高,因此具有临床诊断的价值。

Abstract: Objective  To study the value of MRI and CT in the differential diagnosis of solitary hepatic nodules. Methods From January 2019 to September 2020, 122 patients with suspected solitary liver nodules in our hospital were selected. Methods  RandomLy divided into study group and control group by random number table. 61 cases in study group were treated with MRI, 61 cases in control group were treated with CT. The detection rate, positive rate, sensitivity and specificity of solitary hepatic nodules were analyzed. Results  All 122 cases were confirmed as liver solitary nodules by operation and pathology, 50 cases in the study group and 47 cases in the control group. The detection accuracy of solitary liver nodules in the study group was higher than that in the control group, the difference was statistically significant(P<0.05), and the sensitivity and specificity of the study group were higher than those of the control group. Conclusion  MRI has high accuracy, sensitivity and specificity in the differential diagnosis of solitary hepatic nodules, so it has clinical value.

肝硬化是臨床上常见的慢性进行性肝病,它是一种或多种原因的长期反复作用,导致弥漫性肝损伤[1]。在我国,大多数是肝炎后肝硬化,少数是酒精性肝硬化和血吸虫性肝硬化[2]。病理组织学上可见广泛的肝细胞坏死、残余肝细胞结节性再生、结缔组织增生及纤维间隔形成,导致肝结节结构破坏,形成假小叶[3]。肝脏逐渐变形、变硬并发展成肝硬化。肝脏孤立性结节是肝硬化的主要特征,早期发现肝脏孤立性结节进行及时有效的治疗,是提高生存率的主要方法,CT是临床常用的诊断方法,随着医学的发展,CT也在加速发展,多排螺旋CT在CT的基础上进行发展,目前临床有16排、32排和64排,MRI也是临床常用的诊断方法。本研究分析对肝脏孤立性结节鉴别诊断中使用MRI和CT的价值。
