Užití konformních technik radioterapie a IMRT (intensity modulated radiotherapy) dovoluje šetření okolních zdravých tkání a eskalaci dávky v cílovém objemu. Tyto techniky ve srovnání s konvenčními umožňují větší přesnost v plánování a aplikaci dávky záření. Pro plánování radioterapie je důležité užít takové diagnostické metody, které sníží riziko relapsu nebo komplikací. Základní metodou stále zůstává CT vyšetření, které dovoluje výpočet dávkové distribuce. Zcela nové dimenze přináší PET (pozitronová emisní tomografie), která doplňuje morfologické zobrazení (CT nebo NMR) o zobrazení funkční.

Keywords: Konformní ozařování; IMRT; Klinické použití

Using conformal techniques and IMRT in radiotherapy allows sparing healthy tissues and escalation of the dose in target volume. In comparison with conventional techniques it requires more accuracy in the planning and application of the radiation dose. It is important to use all relevant diagnostic methods to decrease the risk of relapse or complications. CT examination still remains the basic method which allows to calculate the dose distribution. PET brings new dimensions which supplements the morphological image (CT or MRI) with a functional view.

Keywords: Conformal techniques of radiotherapy; IMRT; Clinical applications
