摘要 目的:研究增强CT和超声造影技术在肝脏小占位病变诊断中的临床应用价值。方法:选取2020年1月—2021年3月我院收治的疑似肝脏小占位病变的患者66例作为研究对象,分别对其实施增强CT和超声造影检查,并以患者的穿刺、手术病理诊断结果作为诊断金标准,比较不同方法诊断肝脏小占位病变的准确度以及其对良恶性病变判断的准确度。同时记录不同方法诊断过程中患者的不良反应发生率。结果:经穿刺或者手术病理诊断,确定66例可疑肝脏小占位病变的患者中,共有原发性肝癌45例、转移性肝癌12例、血管瘤患者3例、肝硬化增生结节4例、局灶性结节增生2例,其中良性病变患者9例,占比13.64%;恶性病变患者57例,占比86.36%。以穿刺、手术病理诊断结果为依据,经增强CT和超声造影诊断肝脏小占位病变的准确率分别为86.36%(57/66)、87.88%(58/66),其诊断良性病变的准确率均为66.67%(6/9),其诊断恶性病变的准确率分别为89.47%(51/57)、91.23%(52/57),二者比较均不存在统计学差异(P>0.05)。但是具体到不同类型肝脏小占位病变的诊断中,则可见超声造影在血管瘤上的误诊率显著高于增强CT,在局灶性结节增生上的误诊率则低于增强CT,差异存在统计学意义(P<0.05)。增强CT和超声造影检查后不良反应发生率分别为6.06%和0.00%,增强CT显著高于超声造影,差异有统计学意义(P<0.05)。结论:增强CT和超声造影技术都可以为肝脏小占位病变的诊断提供可靠依据,但在良恶性病变的诊断中,二者各有优缺点,相对而言,超声造影诊断更加便捷、经济、安全,适合大范围推广应用。
