| 目的 评价18F-FDG PET/CT诊断肾脏病合并肿瘤的应用价值。方法 回顾性分析146例肾脏病患者的18F-FDG PET/CT表现，检测病灶最大标准摄取值（SUVmax）；以病理学结果作为诊断金标准，计算18F-FDG PET/CT对肾脏病合并肿瘤的诊断效能。结果 146例肾脏病患者中，29例并发恶性肿瘤，其中肿瘤继发肾损害19例、肾损害伴发肿瘤10例。PET/CT发现72例存在18F-FDG高摄取灶，病灶SUVmax为5.25±3.94；诊断肿瘤34例，最终确诊29例、误诊5例，诊断灵敏度100%（29/29），特异度88.37%（38/43）。肿瘤继发肾损害病灶SUVmax为5.95±3.02，肾损害伴发肿瘤病灶SUVmax为6.58±5.29，差异无统计学意义（P>0.05）。结论 18F-FDG PET/CT可用于筛查肾脏病患者是否合并肿瘤，但对于肿瘤与肾损害关系的诊断价值有限。 |

| Objective To explore the value of 18F-FDG PET/CT in diagnosing renal disease combined with tumor. Methods 18F-FDG PET/CT data of 146 patients with renal disease were retrospectively analyzed. The maximum standardized uptake value (SUVmax) was measured. The results of pathology were taken as the final diagnostic criteria to evaluate the efficacy of 18F-FDG PET/CT in diagnosing tumor in patients with renal disease. Results Totally 29 cases were found combined with tumor, including 19 cases with renal damage secondary to tumors and 10 cases as nephropathy coincident with tumors. PET/CT found 72 cases of 18F-FDG uptake increased (SUVmax=5.25±3.94). 18F-FDG PET/CT diagnosed tumors in 34 cases, including 29 cases were then confirmed and 5 misdiagnosed, the diagnostic sensitivity and specificity of PET/CT was 100% (29/29) and 88.37% (38/43), respectively. SUVmax of lesions of secondary nephropathy by tumor was 5.95±3.02, SUVmax of lesions of nephropathy coincident with tumor was 6.58±5.29, there was no significant difference (P>0.05). Conclusion 18F-FDG PET/CT may be used to screen tumors in patients with renal disease, but it has limited value to explore the relationship between renal disease and tumor. |
