Particle sizes of colloids to be used in sentinel lymph node radiolocalization

Objectives To investigate particle size distribution and possible effects of colloid concentration and time after its preparation on the particle sizes of albumin nanocolloid (Nanocoll), rhenium sulfide nanocolloid (Nanocis) and tin colloid (Hepatate). Methods All three kits were prepared according to the manufacturers' instructions using the following volumes of decayed 99mTc generator eluate: 1.5 ml, 3.5 ml and 5.0 ml (albumin nanocolloid);...
