Enterografia por tomografia computadorizada: uma avaliação de diferentes contrastes orais neutros

Abstract: OBJETIVO: O objetivo deste estudo foi avaliar o desempenho de contrastes orais neutros, comparando a capacidade de distensão intestinal, a distinção da parede intestinal, a aceitação e os efeitos colaterais. MATERIAIS E MÉTODOS: Estudo prospectivo, randomizado e duplo-cego em 30 pacientes submetidos a tomografia computadorizada de abdome e pelve com administração de contraste oral neutro, divididos em três grupos: leite, água e polietilenoglicol. Os exames foram analisados quanto ao grau de distensão intestina… Show more

“…With the utilization of any protocol (three or four phases), one observes a mean dose reduction per scan equivalent to the effective dose of 12.5 mSv, because of the suppression of the acquisition phase without intravenous contrast agent injection. The management of the radiation dose by means of a judicious utilization of the different acquisition phases in protocols of abdominal CT has been the object of several recently published studies (34,35) . The number of patients evaluated in HCC investigation (19 patients) could have been higher, but it was enough to verify, by means of statistical tests, that there was no impact in suppressing the non-contrastenhanced phase, as other studies have already suggested 8) .…”

“…Além disso, a RNM permitiu melhor embasamento da escolha terapêutica em mais de 50% dos casos (MORAES, 2016, p. 40).  Apesar da ampla aplicabilidade e de ótimos resultados da entero-TC, este método tem como principal desvantagem autilização da radiação ionizante, o que limita muitas vezes a indicação a crianças e até mesmo para adultos devido a necessidade de repetição do exame ao longo da vida (AZEVEDO et al, 2014;BURLIN et al, 2017;COSTA-SILVA;MARTINS;PASSOS, 2010;D'IPPOLITO et al, 2012;GOMES, 2016;MARMO, 2017;MATOS et al, 2012;PARENTE, 2012;RENOSTO, 2017;RODRIGO, 2013;TORRÃO et al, 2012).…”

“…In the present issue of Radiologia Brasileira, D'Ippolito et al (8) evaluate the performance of different neutral oral contrast media, comparing capability of bowel distention, intestinal wall definition, patient's acceptance and side effects. The authors describe the In such a study, the PEG concentration was lower than that utilized in previous studies, with the objective of reducing undesirable side effects, while maintaining the capability of intestinal lumen distention.…”

“…Thus, the radiation dose to which such patients are submitted should be taken into consideration, while trying to reduce such radiation dose as much as possible (9) . This latter aspect was approached by the study developed by D'Ippolito et al (8) , where only the enterography phase was performed, as the pre-contrast, arterial and delayed phases would not significantly add new diagnostic data, while quadrupling the radiation dose to which the patients would be exposed. Another option for such population is MRI enterography, whose diagnostic accuracy is similar to that of CT enterography, with the advantage of not relying on ionizing radiation, thus not causing any harm to the patient when repeated multiple times (6) .…”
