SIMPLIFIED LOW IODINE DIET FOR I 131 RADIOIODINE DIAGNOSTIC IMAGING

放射性碘用于诊断甲状腺癌的远处和局部转移以及治疗甲状腺毒症和甲状腺癌。由于美国饮食中碘含量高，除非患者严格接受低碘饮食，否则放射性碘的疗效会降低。 这种由新鲜准备的饭菜和自制面包和意大利面组成的饮食几乎不可能遵循美国人在餐馆吃饭和使用方便食品的饮食习惯。 在对目前可用食物的碘含量进行审查后，本研究的目的是开发和测试一种方便可口的门诊饮食，以将正常志愿者和接受常规放射性碘诊断扫描或治疗甲状腺毒症和甲状腺癌的患者的碘摄入量和排泄量降至50 mcg/24小时以下。

Radioactive iodine is used for the diagnosis of distant and local metastases of thyroid cancer and therapy of thyrotoxicosis and thyroid cancer. Because of the high iodine content of the American diet, the efficacy of radioiodine is diminished unless that patient is placed on a strict low iodine diet. This diet which consists of freshly prepared meals and homemade breads and pastas is nearly impossible to follow with the American dietary habits of eating in restaurants and using convenience foods. After review of the iodine content of currently available foods, the objective of this study is to develop and test a convenient and palatable out-patient diet to decrease iodine intake and excretion to less than 50mcg/24hrs in normal volunteers and patients undergoing routine radioactive iodine diagnostic scanning or therapy for thyrotoxicosis and thyroid cancer.
