摘要
目的总结胆囊癌超声造影特征,探讨胆囊癌超声造影指南对临床的指导意义。方法以2012年制定的胆囊癌超声造影指南为标准,回顾性分析我院70例胆囊癌患者超声造影声像特征并与之进行比较分析;比较不同大小病灶的准确诊断情况。结果 70例胆囊癌患者中,结节型26例,肿块型39例,厚壁型3例,混合型2例;增强模式:由高增强到低增强65例,等增强到低增强3例,低增强到低增强2例;病灶增强开始时间(14.5±2.7)s,达峰时间(22.8±4.0)s,减弱时间(33.4±4.5)s;病变内部血管构筑形态:均匀点状型6例,中央血管型2例,分支血管型10例,不规则血管型52例;病灶最大径<2.0 cm、2.0～3.0 cm、>3.0 cm者分别为7例、14例、49例,超声造影分别准确诊断2例、11例、49例。结论胆囊超声造影强化特征具有一定的共性;指南规范符合临床实践,但在分型、强化时间量化、病灶血管构筑方面,仍有待进一步细化。
Objective To investigate the imaging features of contrast-enhanced ultrasound(CEUS)in the diagnosis of gallbladder carcinoma,and to explore the clinical practicability of the guidelines for CEUS of gallbladder carcinoma.Methods The CEUS characteristics of 70 patients with pathologically diagnosed gallbladder carcinoma were analyzed retrospectively based on CEUS guideline of gallbladder carcinoma.The diagnostic accuracy of different diameter lesions by CEUS were compared.Results The types of gallbladder carcinomas were depicted as nodule type(26/70),mass type(39/70),think wall type(3/70)and mixed type(2/70).In the enhancement pattern,65 lesions showed enhancement from high to low,3 lesions showed equal to low enhancement,while 2 lesions showed low to low enhancement.The initial enhancement time of the lesions was(14.5±2.7)s.The peak enhancement time was(22.8±4.0)s.The weaken enhancement time was(33.4±4.5)s.The vascular structures in gallbladder carcinoma showed that 6 lesions with“homogeneous dotted”type,2 lesions with“central vessel”type,10 lesions with“branch vessel”type and 52 lesions with“irregular vessel”type.There were 7 cases,14 cases,49 cases of maximum with<2.0 cm,2.0~3.0 cm,>3.0 cm,CEUS accurately diagnosed 2 cases,11 cases and 49 cases,respectively.Conclusion The enhancement features of CEUS in gallbladder carcinomas has a certain commonalities,and the guidelines is consistent with clinical practice.However,in terms of typing,quantification time quantification,and vessel vascular construction,the guidelines need to be further refined.
