Lymph node scanning with 99mTc-sulfur colloid.

摘要: Technetium 99m was originally suggested as a possible medical tracer because of its ideal physical properties (1). Subsequently several technetium-99m-labeled radiopharmaceuticals were developed and are now widely used. One them, 99mTc-sulfur colloid, has been employed for years scanning the liver, spleen, bone marrow (2). Studies in animals have shown that this radiocolloid preparation can also be used lymph node scanning. In our experience with patients we found gelatin-stabilized colloid prepared by H2S method is simple, safe procedure scans good quality obtained. Materials Methods slightly modified from one previously described This produces particles substantially smaller than those produced other commonly methods. The particle size not determined precisely so far, but studies biological behavior ...
