摘　　要：【目的】探讨护理质量对正电子发射断层成像-X线计算机断层成像（PET-CT）检查成像质量的影响。【方法】对57例PET-CT检查患者采用检查前准备、药物注射方法、注药后候诊医嘱等护理因素，统计检查成功率、并分析影响图像质量的护理因素。【结果】57例检查成功率100％，其中图片质量以甲、乙、丙、丁判定分别占44例（77．2％）、9例15．8％、4例（7％）与0例。PET-CT图像质量欠佳中数据采集与图像扫描前肠道水化不足造成肠腔生理性浓聚过高，占9例，其中4例做了延迟显像，延迟后发现消化道18 F-脱氧葡萄糖（18 F-FDG）摄取明显减低；示踪剂渗漏形成异常糖代谢增高区3例；尿液污染1例；患者不合作造成PET 与CT图像配准欠佳1例。【结论】护理质量直接影响PET-CT检查成像质量。检查前严格控制血糖水平、加强患者心理护理、充分水化肠道、注药时避免药物外渗、嘱患者避免小便污染衣裤与皮肤以及对不合作的患者适当应用镇静剂等对改善图像质量尤为重要。[Objective]To explore the effect of nursing quality on the image quality of PET-CT scanning .[Methods] The nursing factors such as the preparation before examination ,drug injection method and doctor＇s advice after injection in 57 patients receiving PET-CT scanning were analyzed .The success rate of PET-CT scanning was calculated .The nursing factor affecting the image quality was analyzed .[Results] The success rate of 57 patients was 100% .There were 44 cases（77 .2% ） with 1st image ,9 cases（15 .8% ） with 2nd image , 4 cases（7% ） with 3rd image and 0 case with 4th image .The influential factors of poor PET-CT image included over high physiogenic aggregation in enteric cavity caused by insufficient hydration in intestinal tract of 9 cases in which 18F-FDG uptake in digestive tract of 4 cases was obviously decreased after receiving the delayed scanning ,and 3 cases had abnormal increased glucose metabolism due to tracer leakage ,and 1 case had urine contamination ,and 1 case had poor concordance between PET and CT image .[Conclusion] Nursing quality can directly affect the quality of PET-CT scanning .Controlling blood sugar level ,strengthening mental nursing for patients ,taking sufficient intestinal hydration ,avoiding drug injection leakage ,advising patients to refrain from contamination of clothes and skin by urine and properly using the sedative for dysphoria patients are very important to improve the quality of PET-CT image .
