[en] A ⁸²Sr/⁸²Rb generator was prepared by loading ⁸²Sr to preconditioned tin dioxide column. The generator was eluted by normal saline with flow rate up to 8 ml/min, and the eluted radioactivity was monitored by dose calibrator. Radioactivity began to come out at 5 ml and reached to peak around 9 ml. The total eluted radioactivity increased linearly with flow rate, and the maximum obtained radioactivity was 35mCi at 8 ml/min. The ⁸²Rb preparation was proven to be free from both strontium radioactivity and pyrogen. The ⁸²Rb was injected to normal female volunteer and positron emission tomographic image of heart was obtained successfully.
