摘要：

胆囊癌的影像学检查方法很多，目前临床最常用的是超声检查，CT、磁共振成像（MRI）的应用逐渐普及并显示出在诊断胆囊癌中的重要作用，氟18标记的脱氧葡萄糖正电子发射断层X线摄影（18F-FDG PET-CT）的诊断特异性高，可用于疑难病例的诊断。典型的胆囊癌诊断不难，但早期的胆囊癌诊断仍较困难，彩色多普勒（CDFI）超声和超声造影，CT和MRI动态扫描，MRI的背景抑制磁共振弥散成像（DWIBS）技术以及18F-FDG PET-CT成像有望提高早期胆囊癌的诊断。CT、MRI对胆囊癌邻近结构侵犯及淋巴结转移显示较好，但单凭淋巴结的大小判定淋巴结转移容易漏诊，18F-FDG PET-CT成像及MRI的DWIBS技术有望弥补这些缺陷。

Imageology features and assessment of gallbladder carcinoma        HUANG Sui-qiao. Department of Radiation, Sun Yat-sen Memorial Hospital of Sun Yat-sen University, Guangzhou 510120, China
Abstract    There are many imaging methods in detecting gallbladder carcinoma. Ultrasonography is the most common imaging method now, but the applications of CT and MRI are increased gradually and shown very important in diagnosing gallbladder carcinoma in clinical practice. 18F-FDG PET-CT has very high specificity and can be used in diagnosing difficult cases. It is not difficult for diagnosing typical gallbladder carcinoma, but it is not easy to diagnose early stage of gallbladder carcinoma. The applications of CDFI, contrast-enhanced ultrasound, dynamic CT and MRI scanning, DWIBS technique and 18F-FDG PET-CT will hopefully increase correct diagnosing level for early stage of gallbladder carcinoma. CT and MRI are better in demonstrating invasion of near structures and lymph node involvement due to gallbladder carcinoma. But lymph node involvement can easily get missed diagnosis just based on the size of lymph node. The shortages would be improved by 18F-FDG PET-CT and DWIBS technique.
