【摘要】：原发性胆囊癌是胆管系统最常见的恶性肿瘤。近年来其发病率呈逐步上升趋势,因发病隐匿,多数患者一经发现已属中晚期,从而失去早期手术治疗机会,且恶性程度高、预后极差,因此能否早期明确诊断胆囊癌对患者的预后具有极其关键的意义。目前诊断胆囊疾病常用的影像学方法有超声、计算机断层扫描(CT)、磁共振成像(MRI)和正电子发射断层成像术/计算机断层扫描(PET/CT),随着这些技术不断发展和应用,对胆囊良恶性病变的诊断水平和准确率也得到相应提高。
[Abstract]:Primary gallbladder carcinoma is the most common malignant tumor in the bile duct system. In recent years, the incidence of gallbladder carcinoma is increasing gradually. Because of the occult disease, most of the patients have been found to be in the middle and late stage, thus losing the opportunity of early surgical treatment. And the degree of malignancy is high, the prognosis is very poor, so it is very important to diagnose gallbladder carcinoma in early stage. At present, the commonly used imaging methods for diagnosis of gallbladder diseases are ultrasound. Computed tomography (CT), magnetic resonance imaging (MRI) and positron emission tomography (PET) / computed tomography (CT) have continued to develop and apply with these technologies. The diagnostic level and accuracy of benign and malignant gallbladder lesions were also improved.

【正文快照】： 在胆管系统的恶性肿瘤中,最常见的是原发性胆囊癌[1],其恶性程度高、预后极差,进展期时胆囊癌患者的中位生存期只有3~6个月,5年生存率低于5%[2]。影像学上胆囊癌常分为厚壁型、腔内型和肿块型[3]。部分胆囊良恶性病变鉴别诊断仍存在一定困难,如厚壁型胆囊癌需与慢性胆囊炎、黄
