Uvod: Pri preiskavah s pozitronsko emisijsko tomografijo v kombinaciji z računalniško tomografijo (PET/CT preiskavah) se uporablja ionizirajoče sevanje višjih energij kot pri klasičnih nuklearno medicinskih preiskavah. Posledično bi zdravstveni delavci, ki sodelujejo pri PET/CT preiskavah, lahko prejeli večje doze sevanja kot pri klasičnih nuklearno medicinskih preiskavah. Namen: Namen magistrske naloge je bil ugotoviti, ali so se po uvedbi PET/CT preiskav na Kliniki za nuklearno medicino (KNM) v Univerzitetnem kliničnem centru v Ljubljani prejete osebne doze sevanja pri zdravstvenih delavcih, ki so sodelovali pri izvedbi PET/CT preiskav, spremenile. Material in metode: Delavci – v raziskavo smo vključili 27 delavcev (7 zdravnikov, 10 diplomiranih inženirjev radiologije, 5 farmacevtov in 5 diplomiranih medicinskih sester) z diagnostičnega oddelka KNM. V letih 2008 in 2009 so omenjeni delavci sodelovali pri klasičnih nuklearno medicinskih preiskavah, v letih 2010–2012 pa so poleg tega sodelovali tudi pri PET/CT preiskavah. Metode dela – za zgoraj navedene skupine delavcev smo poiskali in analizirali podatke dozimetričnih meritev za obdobje 2008–2012, ki jih je opravil Zavod za varstvo pri delu (ZVD). Poleg tega smo zdravnikom, diplomiranim inženirjem radiologije in farmacevtom, ki so sodelovali pri PET/CT preiskavah, določili dnevne doze sevanja. To smo naredili s pomočjo elektronskih dozimetrov, ki smo jih predhodno umerili. Rezultati: Zaradi sodelovanja pri PET/CT preiskavah se je letno prejeta doza sevanja statistično značilno povečala pri zdravnikih – leta 2009 so prejeli povprečno 0,18 mSv, leta 2010 pa 0,39 mSv (p= 0,005) in pri diplomiranih inženirjih radiologije – leta 2009 so prejeli 0,82 mSv, leta 2010 pa 1,04 mSv (p= 0,034). Zaradi sodelovanja pri PET/CT preiskavah se letno prejete doze sevanja pri farmacevtih in diplomiranih medicinskih sestrah niso statistično značilno spremenile. Povprečna dnevna doza sevanja, ki jo je prejel zdravnik zaradi sodelovanja pri PET/CT preiskavah, je znašala 3,1±2,4 μSv. Dva radiološka inženirja, ki sta sodelovala pri PET/CT preiskavah sta dnevno prejela skupno 5,1±3,4 μSv, farmacevt pa <1 μSv. Povprečna doza sevanja, ki jo je prejel zdravnik pri eni PET/CT preiskavi, je znašala 0,34 μSv. Doza sevanja, ki jo je prejel diplomiran inženir radiologije, pa 0,28 μSv. Zaključek: Zaradi uvedbe PET/CT preiskav so se letno prejete doze sevanja pri delavcih na KNM zmerno povečale. Statistično značilno povečanje je bilo prisotno pri zdravnikih in diplomiranih inženirjih radiologije. Pri farmacevtih in diplomiranih medicinskih sestrah se letno prejete doze sevanja zaradi uvedbe PET/CT preiskav niso pomembneje spremenile. Povprečne doze sevanja, ki so jih pri eni PET/CT preiskavi prejeli delavci na KNM, so manjše od navedb v literaturi. Po našem mnenju je to predvsem posledica dobre organizacije dela in doslednega upoštevanja načel varstva pred ionizirajočimi sevanji.

Sekundarni naslov: Radiation doses of employees of Nuclear Medicine Department before and after introduction of PET/CT
Sekundarni povzetek: Introduction: In positron emission tomography / computed tomography (PET/CT) examinations ionising radiation of higher energies is used compared to classical nuclear medicine examinations. Consequentially, health care workers, who work with PET/CT, could receive higher radiation doses than health care workers who work in classical nuclear medicine. Purpose: The purpose of the master's thesis was to explore if introduction of PET/CT examination procedures to the Department for Nuclear Medicine (KNM) at the University Medical Centre in Ljubljana has affected in elevated personal radiation doses of health care workers who are executing PET/CT examinations. Materials and methods: The research included 27 workers from the diagnostic centre of KNM: 7 physicians, 10 radiologic technologists, 5 radiopharmacists, and 5 qualified nurses. In the years 2008 and 2009 these workers were performing classical nuclear medicine examinations, whereas in the years from 2010 to 2012 they also worked with PET/CT examinations. Research methods – we analysed the radiation dose measurements for the period 2008–2012, which had been measured with personal thermoluminiscent dosimeters and read by the Institute Occupational Safety. Additionally, we measured daily personal radiation doses for physicians, radiologic technologists, and radiopharmacists who cooperated in PET/CT examinations. We used calibrated electronic dosimeters. Results: As a consequence of cooperation in PET/CT examination procedures, the annual radiation dose has significantly increased for physicians (mean dose 0.18 mSv in year 2009 and 0.39 mSv in 2010; p = 0.005) and for the radiologic technologists (mean dose 0.82 mSv in 2009 and in 1.04 mSv in 2010; p = 0.034). The radiation doses for radiopharmacists and qualified nurses have not significantly changed. Mean daily radiation dose, received by a physician performing PET/CT examination procedures, was 3.1±2.4 μSv. Two radiologic technologists who cooperated in PET/CT examinations as a team, received combined daily dose of 5.1±3.4 μSv and the radiopharmacist received <1 μSv. A mean radiation dose, received as a consequence of collaboration in a single PET/CT examination, was 0.34 μSv for a physician and 0.28 μSv for radiologic technologist. Conclusion: Following the introduction of PET/CT examinations, the annual radiation doses have increased for health care workers at KNM. Statistically significant increase was measured for physicians and radiologic technologists. For radiopharmacists and qualified nurses the increase was not statistically significant. Mean radiation doses, received by workers in one single PET/CT examination, were lower than measurements reported in the literature. This observation might be a consequence of good organization of work and consistent abiding with the ionising radiation protection rules.
