Abstract 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 scan-ning ,and 3 cases had abnormal increased glucose metabolism due to tracer leakage ,and 1 case had urine con-tamination ,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 .
