1.前言做为肝胆道核医学的诊断方法,从前使用过各种放射性碘标记的染料药品。但是,对于~(131)碘的物理性质、辐照剂量问题都不能忽视,从而使投予量受到限制,使胆道不能充分显影是其不足之处。做为它的代用放射性药品;~(99m)锝标记化合物的研究陆续有成果报告。这次,作者把研制的~(99m)锝-N-[N’-(2,6-di-methylphelnyl)carbamoylmethyl]iminodiace-ticacid(以下简称~(99m)锝-HIDA),做为新的肝胆
1. Introduction As a diagnostic method for liver and gallbladder nuclear medicine, a variety of radioactive iodine-labeled dye drugs have been used before. However, for the 131I iodine physical properties, the radiation dose can not be ignored, so that the dosage is limited, so that the bile duct can not be fully developed its deficiencies. As its alternative radiopharmaceuticals; ~ (99m) technetium labeled compounds have been reported in succession. This time, the author made a new hepatobiliary (~ (99m) technetium-HIDA ~ 99m technetium-N- [N ’- (2,6- di-methylphelnyl) carbamoylmethyl] iminodiacetic acid
