直径≤30mm肝癌的声像图征象及其临床价值

摘要

目的:探讨肝癌占位直径≤30mm的超声声像图征像,探讨其在诊断肝癌中的应用价值.方法:临床纳入占位直径≤30mm的肝癌患者40例,同时纳入占位直径≤30mm的肝脏良性病变患者30例作为对照组,所有患者均进行超声检查,同时行CT检查,观察超声与CT在临床诊断以及鉴别诊断直径≤30mm的肝癌的准确性与两者之间的相关性.结果:超声、CT诊断肝癌占位直径≤30mm者的临床准确率分别为80.00％、82.50％,差异无显著性(P＞0.05),两者之间存在较好的相关性(k=0.67).另外,超声与CT比较,检查费用相对低廉,符合药物经济学的要求.结论:超声与CT检查均是目前临床上诊断与鉴别直径≤30mm肝脏占位病变的主要手段,均能够清晰地显示不同肝局灶性病灶的血供特征.由于超声检查简便、无放射性,因此可以作为直径≤30mm肝脏占位病变临床诊断以及鉴别诊断的首选.%Objective:To explore the ultrasonography signs (space-occupying diameter ≤30mm) and its clinical application value in liver cancer patients.Methods:40 liver cancer patients (space-occupying diameter≤30mm) were selected.In addition,30 patients with begnign hepatic lesion (space-occupying diameter≤30mm) were selected as control group.The ultrasonography and CT examination was conducted.Based on two methods,the accuracy and correlation in the differential diagnosis of liver cancer (spaceoccupying diameter≤ 30mm) was analyzed.Results:During the diagnosis of liver cancer (space-occupying diameter≤30mm),the accuracy based on ultrasonography and CT examination was 80.00％ and 82.50％ (P＞0.05);the ultrasonography and CT examination had a fair correlation (k=0.67).Compared with CT examination,the inspection charge based on the ultrasonography was more economic.Conclusion:The ultrasonography and CT examination are the major methods in the differential diagnosis of hepatic lesion (space-occupying diameter≤ 30mm) of which the blood supply feature of the different hepatic lesions is clearly displayed.Since the ultrasonography is easy to operate and has no radioactivity,it can be regarded as the first choice in the differential diagnosis of hepatic lesion (space-occupying diameter≤ 30mm).
