191mIr is a useful tracer for radionuclide angiocardiography and may be of particular value in the evaluation of heart disease in children. It has a short half-life, a suitable photon energy, and may be obtained as a generator product by decay of its long-lived parent 191Os. A 191Os-191mIr generator capable of providing at least 18 mCi of 191mIr in 1.5 ml of eluant is described. 191mIr is separated from 191Os by absorbing 191OsCl6(-2) on an ion exchange resin and eluting with a solution of 8.7% NaCl at a pH of 2.2. The generator employs an additional resin column which is replaced to minimize 191Os breakthrough.
191m铱是放射性核素心血管造影术中一种有用的示踪剂，在评估儿童心脏病方面可能具有特殊价值。它半衰期短，光子能量合适，可通过其长寿命母体191锇衰变作为发生器产物获得。描述了一种191锇 - 191m铱发生器，它能够在1.5毫升洗脱液中提供至少18毫居里的191m铱。通过在离子交换树脂上吸附191锇氯络阴离子（191OsCl6(-2)）并用pH值为2.2的8.7%氯化钠溶液洗脱，将191m铱与191锇分离。该发生器采用一个额外的树脂柱，更换此树脂柱可使191锇的穿透最小化。
