When Ferenc Deak was elected in 1843 as a parliamentary representative in the county of Zala after a campaign of extraordinary size and intensity, involving accommodation, free travel, and bribes offered to the voters, Deak, then one of the leaders of the liberal reformer opposition, refused to take his seat with reference to the fact that his election had been achieved by illegal means of campaign and had cost some thirty thousand forints to his supporters. The present study is based upon the extant financial accounts of the campaigning expenses, confidential private correspondence and reports of the secret police and of the contemporary press. After outlining canvassing as done by the conservatives who opposed noble taxpaying, the study describes in detail through an analysis of all known sources the two-month election campaign of the liberals who supported the taxation of the nobility, and the costs it involved. According to our sources, whereas the conservative campaign was funded chiefly by the Catholic clergy, and before all by the bishop of Veszprem, the liberals were financed by the local Jewish merchants who advanced the loans needed for a successful campaign.

Positron emission tomography (PET) is a medical imaging method belonging to the realm of nuclear medicine. It has been a clinical research tool since the sixties but during the late nineties it became widely utilized in clinical practice too. PET technique requires special radioactive isotopes, which may be generated only in particle accelerators (cyclotrons) and their transport is limited owing to the short physical half-life. PET/CT was born from the combination of PET and CT (computer tomography). The first combined PET/CT scanner began to operate in 1998 and the method has been used in clinical practice since 2001. It is a hybrid (multi-modality) medical imaging equipment which can provide anatomical, morphologic (CT) and functional, metabolic information (PET) simultaneously. PET/CT imaging has gained clinical acceptance mainly in oncology - owing to the attributes of the most frequently used PET tracer, fluoro-deoxy glucose (FDG) - and in a lesser extent in neuropsychiatry and cardiology. The authors in this paper review the basics and key indications of the method, the wider used radiofarmacons, including potential neurological and psychiatric applications, and the possible causes of false positivity and false negativity.
