Figure 8 illustrates the use of somatostatin which binds to specific receptors on malignant cells when linked
with a spacer ( DOTA) TOC or NOC and be synthesized and combine with Gallium 68 and used a s a sensitive
and quantifiable tracer for scanning with many advantages over the Octreoscan and combined with Ytrium 90
or Lutetium 177 can be used of peptide receptor radiotherapy with a 3-9 mm kill range depending on being a
