Scintillation camera imaging with I-123. 1979

L S Graham, and F W Zielinski

Iodine-123 produced from three different nuclear targets (Te-122, Te-124, and I-127) was evaluated for spatial resolution and sensitivity with an Anger scintillation camera. Te-122 targets generated a substantial amount of I-130, which necessitated use of a medium-energy collimator. Te-124 targets produced solutions with significant amounts of I-124. Shortly after the end of bombardment, a 4,000-hole (4KH) collimator was satisfactory; at 30 hours, a medium-energy collimator was required. High-purity I-123 from an I-127 target gave excellent spatial resolution when the 4KH collimator was used, but low-energy "foil" collimators were not adequate.

D011877 Radionuclide Imaging The production of an image obtained by cameras that detect the radioactive emissions of an injected radionuclide as it has distributed differentially throughout tissues in the body. The image obtained from a moving detector is called a scan, while the image obtained from a stationary camera device is called a scintiphotograph.
