SIMPLIFIED LOW IODINE DIET FOR I 131 RADIOIODINE DIAGNOSTIC IMAGING

放射性碘用于甲状腺癌远处和局部转移的诊断以及甲状腺毒症和甲状腺癌的治疗。由于美国饮食中碘含量高，放射性碘的疗效减弱，除非病人被置于严格的低碘饮食中。这种饮食包括新鲜准备的饭菜和自制的面包和意大利面，几乎不可能与美国人在餐馆吃饭和使用方便食品的饮食习惯相符合。在回顾了目前可用食物的碘含量后，本研究的目的是开发和测试一种方便和美味的门诊饮食，以将正常志愿者和接受常规放射性碘诊断扫描或甲状腺毒症和甲状腺癌治疗的患者的碘摄入量和排泄量减少到低于50微克/24小时。

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.
