Preparation of a 99mTc-Sn-MAA kit for use in nuclear medicine.

A method of preparation of an MAA kit which has a high labeling efficiency with /sup 99m/Tc, a consistent particle size, and stability with time is descibed. This kit can be prepared in varying amounts and should allow most nuclear medicine departments to take advantage of the desirable physical characteristics of /sup 99m/Tc. (auth)
