Biography

Pal Mikecz has received his University Doctoral Degree in 1988

based on the work of Production Methods of Medically Im-

portant Radioisotopes which was conducted in Joint Nuclear

Research Institute in Dubna. Since then, he had participated in

establishment and running a few PET radiochemistry laborato-

ries in Hungary, Scotland, Poland and Germany. He has recently

retired from the University of Debrecen. He is Senior Advisor for

the Radiochemistry Laboratory of the newest Hungarian PET

centre at the Kaposi Mór Teaching Hospital in Kaposvár. He had

participated in several IAEA mission as an Expert in the field of

PET Radiochemistry. He has published more than 50 papers in

reputed journals with 500+ citations and has been serving as

Reviewer of many articles.

ositron emission tomography (PET) could significantly improve the radiation

therapy planning by increasing the targeting accuracy and therapeutic efficacy

of the delivered radiation. Since this method gives information of the biochemistry

of tissues, it should be a necessary supplement to the anatomical imaging

methods such as CTor MRI. Themain advantage is its ability in imagemetabolism,

apoptosis, proliferation, cellular transporters, cell receptors, oxygen availability,

gene expression and cell kinetics, non-invasively in living subjects at multiple time

points. Besides the 2-[fluorine-18] fluoro-2-deoxy-D-glucose (FDG), the most often

applied radiopharmaceutical, there are several other well established but much

less used tracers. The use of other tracers is often hindered by price and the lack

of availability of these tracers. The second most frequently used tracer family

is the fluorine-18 or carbon-11 labelled amino acids like [11C] methionine, [

18

F]

Fluoro (methyl or ethyl) tyrosine or even [

18

F] FDOPA (fluorodopa). The carbon-11

and fluorine-18 labelled choline analogues could be useful in prostate tumour

metastases or in some cases in gliomas. Since hypoxic tumour cells are relatively

resistant to radiation and would be more likely to be controlled if a higher radiation

dose could be accurately targeted at regions of imaged hypoxia with [

18

F] FMISO

(fluoromisonidazole) or [

18

F] FAZA (Fluoroazomycin arabinoside ). The ideal

radionuclide for PET imaging is fluorine-18 due to its ideal nuclear properties.

Application of other nuclides is always call for compromise in image quality. The

acceptance of the radiopharmaceuticals by the end users, i.e., clinicians and the

patients is important, however, the approval by the national regulatory agency and

above all reimbursement for theparticular clinical indicationare critical factors that

determine the success of a scientifically useful molecular imaging agent. Recently

in Hungary there are four tracers that are available for human applications. Their

use for radiation therapy planning so far was not commenced.
