摘　　要：目的研究^(18)F-FDG PETCT显像对膀胱癌的诊断价值。方法选取我院核医学科2013年3月-2015年2月收治的34例可疑膀胱癌患者,术前分别采用增强CT和^(18)F-FDG PETCT显像进行诊断,通过参考手术病理结果回顾性分析^(18)F-FDG PETCT显像诊断的效果。结果该34例经手术病理观察均确诊为移行细胞癌,增强CT、^(18)F-FDG PETCT显像诊断准确度分别为91.18%、94.12%,差异无统计学意义(P<0.05);术中共有11例膀胱肿瘤出现盆腔淋巴结或邻近组织转移、浸润,^(18)F-FDG PETCT显像诊断准确度为72.73%,明显高于增强CT(27.27%),具有统计学意义(P<0.05)。结论 ^(18)F-FDG PETCT显像和增强CT均是临床诊断膀胱癌的有效方法,但^(18)F-FDG PETCT显像在观察膀胱肿瘤病灶的转移和对邻近组织的浸润效果较好,对指导临床诊断和了解肿瘤病变具有重要参考价值。Objective To study the value of18F-FDG PETCT imaging in the diagnosis of bladder cancer.Methods 34 cases of patients with suspected bladder cancer who were admitted in the department of nuclear medicine of our hospital between March 2013 and February 2015 were included in the study. Before operation, the patients were diagnosed by enhanced CT and18F-FDG PETCT imaging respectively. The effect of18F-FDG PETCT imaging diagnosis was retrospectively analyzed with reference to the pathological results.Results All the 34 cases were diagnosed as transitional cell carcinoma by operation and pathology. The diagnostic accuracy rates of enhanced CT and18F-FDG PETCT imaging were 91.18% and 94.12%, respectively （P〈0.05）. There were 11 cases of bladder tumors with presence of pelvic lymph nodes or adjacent tissue metastasis and infiltration. The accuracy of18F-FDG PETCT imaging diagnosis （72.73%） was significantly higher than that of the enhanced CT （27.27%） （P〈0.05）.Conclusions Both of18F-FDG PETCT imaging and enhanced CT are effective methods for the clinical diagnosis of bladder cancer, but18F-FDG PET-CT imaging is better at observing bladder tumor metastasis and adjacent tissue infiltration. It is of important reference value in guiding the clinical diagnosis and understanding of the neoplastic lesions.
