The radioiodine 123I, on the other hand, is very useful in nuclear medicine because it has good radiation characteristics for scintigraphy, such as decay by electron capture, a half-life of 13 h, and y emmision of 159 keV. However, the much shorter half-life, together with the more complex radionuclide production, makes this radionuclide less available and more expensive compared to 131I.

In the medical field, Tl (radioactive half-life 73 h) is used for diagnostic purposes in the heart and circulatory system, as well as for nuclear imaging of bone tumors (thallium scintigraphy) (Sumiya et al. 2001).

Nuclear medicine procedures play a substantial role in patient selection, therapy planning, treatment monitoring and follow-up. F-FDG PET/CT, SPECT with macroaggregated albumin and post-therapeutic bremsstrahlung scintigraphy are the most important techniques used for this purpose.

Both thallium 203 and 20S (70.5%) have a nuclear spin and nuclear magnetic resonance signals are detectable for these isotopes. Radioactive ° T1 is used extensively as an imaging agent in myocardial scintigraphy. 

Pulmonary scanning of gallium 67 citrate is widely used in nuclear medicine departments for the detection of cancers and the active inflammation associated with interstitial lung disease and may also reflect macrophage activity. Tsuchiya et al. (41) demonstrated that the uptake measured by gamma-scintigraphy correlates with the expression of transferrin receptors (TFRs)... 

An X-ray fluorescence scanner is at least as expensive as an analogous piece of equipment for the classical scintigraphy complete with all the necessary accessories. The latter is therefore suitable for use in all field in which in vivo nuclear medicine diagnostics are valuable. An X-ray fluorescence scanner developed and built for thyroid investigations may be used to obtain morpho-functional images only of the thyroid besides, these images show a not better resolution than that of radionuclides images.
