Resumo
O recurso à Tomografia Computorizada (TC) como meio complementar de diagnóstico tem vindo a aumentar no panorama internacional, de forma mais acentuada nos últimos anos. Apesar da reduzida preponderância dos exames de TC face aos outros exames de radiodiagnóstico, a TC caracteriza-se por contribuir grandemente para a dose efetiva. Estima-se que em Portugal a TC contribuí para 74 % da dose efetiva coletiva total. Esta revisão reúne dados sobre a evolução temporal do número de exames de TC em Portugal, enquadrada no contexto internacional, com base em fontes de literatura nacional e internacional. À semelhança da realidade internacional, concluiu-se que, em Portugal, o número de exames aumentou aproximadamente 10 % anualmente, entre 1995 e 2011.
The use of Computed Tomography (CT) as a complementary diagnostic technique has increased internationally, most markedly in recent years. Despite the low frequency of CT scans compared to other radiology examinations, CT is characterized as contributing significantly to the effective (radiation) dose. In Portugal, it is estimated that CT contributed 74 % of the total collective effective dose. This review gathers data on the temporal evolution of the number of CT scans in Portugal, framed in an international context, based on national and international literature sources. It was concluded that, in Portugal, as internationally, the number of CT scans increased by approximately 10 % annually, between 1995 and 2011.
