Abstract
Purpose: Any use of ionizing radiation must be justified, and the benefit must be greater than the harm it causes. Imaging must be performed with the lowest possible dose received by the patient while maintaining optimal radiographic image quality. Imaging of the lumbar spine is a relatively high dose imaging procedure. This systematic review aims to explore optimization options to reduce patient exposure while maintaining radiographic quality during plain lumbar spine imaging. Methods: A systematic review of the literature from the databases Pub Med Central, EBSCOhost including CINAHL, Cochrane Library, Web of Science, Science Direct, DiKUL and Springer Link. The documents were fully accessible and in English language. Results: 26 experimental studies were included in the analysis. There are many optimization methods: changing the tube potential, comparisons of different projections, use of shielding, primary beam collimation, increasing the source-to-image receptor distance, compression of the imaged area, using the air gap technique, evaluation of the need for additional projections, and rotating the patient depending on the tube side. On average, the dose is reduced by 44%. Studies that also evaluated the quality of radiographs found all radiographs to be diagnostically acceptable. Conclusion: The results confirm a reasonable use of methods to optimize radiation exposure and to maintain an optimal image quality of radiographs. A systematic review for each specific area in general radiography would be useful sometime in the future.

Title:Optimizacija posegov v radiološki tehnologiji – slikanje ledvene hrbtenice v splošni radiologiji
Abstract:
Namen: Vsaka raba virov sevanja mora biti upravičena, korist, ki jo dosežemo z uporabo ionizirajočih virov pa mora biti večja od škode, ki jo povzroči. Postopke slikanja moramo izvajati tako, da pacient pri slikanju prejme najnižjo dozo, ki je še razumno dosegljiva ob optimalni kakovosti rentgenograma. Slikanje ledvene hrbtenice spada med preiskave z relativno visoko dozo ionizirajočega sevanja. Namen sistematičnega pregleda je raziskati možnosti optimizacije v smislu zniževanja doze na paciente in hkratni ohranitvi kakovosti rentgenogramov na področju slikanja ledvene hrbtenice v splošni radiologiji. Metode: Narejen je bil sistematični pregled literature s pregledom podatkovnih baz Pub Med Central, EBSCOhost preko CINAHL, Cochrane Library, Web of Science, Science Direct, DiKUL in Springer Link. Dokumenti so bili iskani v polnem besedilu in v angleškem jeziku. Rezultati: V analizo je bilo vključenih 26 eksperimentalnih raziskav. Kot možnosti za optimizacijo so bile uporabljene različne metode spreminjanja napetosti, primerjava različnih projekcij, uporaba svinčenih zaščit, zaslanjanje primarnega polja, povečanje razdalje od izvora do slikovnega sprejemnika, kompresija slikanega področja, ocenjevanje potrebe po dodatni projekciji slikanja ter obračanje pacienta glede na postavitev rentgenske cevi. Povprečna doza ionizirajočega sevanja se zmanjša za 44 %. Raziskave, v katerih so poleg doze ocenjevali še kakovost rengenogramov, med ocenami niso opazili statistično značilnih razlik oz. rentgenogrami so bili diagnostično sprejemljivi. Zaključek: Rezultati potrjujejo smiselno uporabo metod za optimizacijo tako na področju zniževanja doze kot tudi ohranjanja optimalne kakovosti rentgenogramov. V prihodnje bi bilo smiselno narediti sistematični pregled za vsako posamezno področje v splošni radiologiji.
