| 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 以胆囊癌超声造影指南为标准，回顾性分析我院胆囊癌患者超声造影声像特征并与之比对。结果 胆囊癌分型：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，无增强0例；病灶增强开始时间14.5±2.7（s），增强达峰时间22.8 S±4.0（s），增强减弱时间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。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。在分型、强化时间量化、病灶血管构筑方面,指南有待进一步细化。 |

| Abstract: |
| objective To investigate the clinic imaging features of the contrast-enhanced ultrasound(CEUS)in the diagnosis of gallbladder carcinoma , so as to discuss about the clinic practicability of contrast-enhanced ultrasound guideline of gallbladder carcinoma in 2012. Methods Based on Contrast-enhanced ultrasound guideline of gallbladder carcinoma in 2012, the characteristics of CEUS were reviewed in 70 patients with gallbladder carcinoma proven pathologically. Results The types of gallbladder carcinomas were depicted as mass type(26/70),nodule type(39/70), think wall type(3/70)and Mixed type(2/70). In the enhancement pattern, two lesions showed hypo-enhancement (2/70) ,while most of patients with other lesions showed iso-enhancement(3/70) or hyper-enhancement(65/70)during initial period and hypo-enhancement during late period. The time to initial enhancement of the livers was (18.2±2.7)s. The time to initial enhancement of the lesions was (14.5±2.7)s. The time to peak enhancement was (22.8±4.0)s. The time to hypo-enhancement was (33.4±4.5)s. The vascular structures in gallbladder carcinoma were shown “homogeneous dotted” type(6/70), “central vessel” type(2/70), “branched vessel” type(10/70) and “irregular vessel ”type(52/70). Conclusions The enhancement pattern of CEUS in gallbladder carcinomas has its characteristics, and our practice is consistent with the guideline. But in many respects, such as type of classification, quantitative of the enhancement time and vascular structures, the guideline needs further elaboration. |
