儿科核医学泌尿系检查除能提供肾脏及集尿系解剖结构信息外,还能获得重要生理功能参数,其中对肾功能测定尤有价值。这主要归因于有符合肾功能测定要求的放射性药物及放射性核素(核素)示踪、成像技术。核素方法检测儿童肾功能主要有肾小球滤过率(GFR)、有效肾血浆流量(ERPF)和肾图测定。现就这些检查原理、方法及临床应用作一简述。 Pediatric nuclear medicine urinary examination in addition to provide anatomical information on the kidney and urinary system, but also access to important physiological function parameters, of which renal function is particularly valuable. This is mainly due to the radiopharmaceutical and radionuclide (nuclide) tracer and imaging techniques that meet the renal function test requirements. The radionuclide method for detection of renal function in children mainly includes glomerular filtration rate (GFR), effective renal plasma flow (ERPF) and renal mapping. Now on these principles, methods and clinical application of a brief review.
