Studies on 66,67Ga- and 199Tl-poly(N-vinylpyrrolidone) complexes.

Gallium and thallium radionuclides have both diagnostic and therapeutic applications in the field of nuclear medicine. Poly(N-vinylpyrrolidone) (PVP) is routinely used as a drug base because of its excellent biocompatibility. In this paper, complex formation abilities between no-carrier-added (66,)(67)Ga/(199)Tl radionuclides and PVP have been studied. It has been found that aqueous 5% PVP solution can almost quantitatively back extract (66,)(67)Ga/(199)Tl radionuclides from an organic phase, which proves the complexing ability of PVP with (66,)(67)Ga/(199)Tl. Tl(3+) is more efficient to form Tl-PVP complexes than Tl(+). However, Tl(3+)-PVP complexes are less stable than Ga(3+)-PVP complexes.

[The role of gallium scintigraphy in the diagnosis of sarcoidosis and in monitoring treatment effectiveness].

Sarcoidosis is an inflammatory disorder of unclear origin that can affect many organs. The hallmark of sarcoidosis is formation non-caseating epithelioid cell granulomas. The aetiology and the pathogenesis of the disease are not well understood, therefore in the absence of specific histopathology distinguishing marks the diagnosis is established by exclusion. In this case, the authors present a unique case of Boeck sarcoidosis with pulmonary manifestation and pleural involvement. They would like to draw attention to the importance of gallium scintigraphy in the diagnostic workup of the disease. During the diagnostic process, the exact diagnosis could be established with the help of gallium scintigraphy. Gallium scan also played an important role in identifying extrapulmonary manifestations. Serial control examinations--as being the only sensitive non invasive diagnostic test method- provided valuable help in estimating the activity of the inflammatory process and monitoring therapeutic efficacy.

[Effects of transmission counts on image quality during simultaneous emission/transmission scan].

We compared the pre-injection transmission scan with the simultaneous emission/transmission scan (SET) using a body phantom in positron emission tomography (PET) to study the factors affecting emission (EMIS) images with different transmission (TRAN) data. The results showed that total count, region, scan method, and EMIS component influenced the bias and noise statistics. This influence was further passed on to the EMIS data and affected the reconstructed image. However, the result of fixing EMIS scan time at 10 minutes was that the noise statistics of EMIS had a greater effect on image quality than TRAN. The optimal scan counts of SET in this study were 20 Mcounts, with a scan time of about 10 minutes (85.5 MBq, (68)Ge-(68)Ga radioactivity). In clinical use, optimal collection count differs, as radiation TRAN quantity depends on the size of the subject, even with fixed radioactivity of (68)Ge-(68)Ga.
