影象技术的进步使人们对核医学在泌尿学科中的价值产生了怀疑,然而新的放射性同位素、γ照相机的出现和动态研究又明确保留了核医学的地位,尤其在某些肾、肾上腺、膀胱和阴囊疾患的评价中。肾脏:与X 线照相术相比,核医学有许多优点,如放射量低,不受肠腔气体、骨胳、各种造口和收集装置的影响,可重复提供可靠、定量的功能资料,很少出现过敏反应。肾脏的放射性核素可分为(1)肾小球滤过并迅速排出
Advances in imaging technology cast doubts on the value of nuclear medicine in urology. However, the advent and dynamic studies of new radioisotopes and gamma cameras have clearly retained the status of nuclear medicine, especially in the kidney, adrenal, Bladder and scrotal disorders are evaluated. Kidneys: Compared with radiography, nuclear medicine has many advantages, such as low radiation dose, free from intestinal gas, bone, various stoma and collection devices, and can repeatedly provide reliable and quantitative functional data, Allergic reactions rarely occur. Kidney radionuclides can be divided into (1) glomerular filtration and rapid discharge
