<p>A process for making a lyophilized composition useful for skeletal imaging whereby an aqueous solution containing an ascorbate, gentisate, or reductate stabilizer is contacted with tin metal or an alloy containing tin and, thereafter, lyophilized.</p><p>Preferably, such compositions also comprise a tissue-specific carrier and a stannous compound. It is particularly preferred to incorporate stannous oxide as a coating on the tin metal.</p> |
