“…Viswanathan et al 13 reported that ct and mri are similar with respect to oar contouring and dvh analysis, but that mri is superior in terms of contouring the various gec-estro tumour definitions 6 . Other studies have shown that dvh analysis of 2D plans reveals suboptimal coverage of the ct-based cervix and a negative correlation between coverage and cervix size 16 . More Canadian centres have implemented some mri planning into their processes-albeit only for 1 insertion in most centres because of limited access to mri.…”

“…This allows for the determination of problematic volumetric doses to OAR and instances where dose shapes should be altered to reduce the risk of complications (Davidson et al, 2008). Another authors investigated two-dimensional (2D) radiograph-based plans using 3D dosevolume histogram (DVH) parameters following guidelines from Gynecologic GEC-ESTRO Working Group (Gao et al, 2010). Clinical target volume (CTV), bladder volume, rectum volume, sigmoid colon, and small bowel were delineated on CT images.…”

“…O planejamento 3D já é amplamente utilizado para tratamentos de teleterapia, inclusive para o tratamento do câncer do colo uterino e vem sendo utilizado para braquiterapia, principalmente fora do Brasil (Gao, et al, 2010;Assenholt, 2008).…”

“…Segundo Gao (Gao, et al, 2010), a dose num volume de 2 cc do órgão tem uma maior significância quando se faz uma análise volumétrica, já que apresenta uma dependência menor da grade de cálculo utilizada no sistema de planejamento, tem menor influência de possíveis erros de contornos, tem uma boa correlação com a dose máxima do órgão e é clinicamente mais relevante que uma dose pontual. Neste trabalho, para a bexiga, D 2cc foi maior que a dose no ponto de bexiga.…”
