Its application has grown worldwide. Around 50% of all cancer patients should receive radiation. Brazil faces a shortage of radiotherapy treatment because of a lack of enough treatment units, equipment availability, well-trained staff, and fair reimbursement. The Radiotherapy Information System (RIS) implementation to manage information about patient scheduling is vital to improve the efficiency of care and reduce the waiting time to start cancer treatment. The information system deployed can be indicated as a disruptive innovation in the Brazilian public health system, considering the radical improvement in the cancer treatment process at the Brazilian National Cancer Institute.

Materials and methods: We studied 8 patients with NMO and 17 without any neurologic disorder. Also, 32 MS patients were selected. Fractional anisotropy (FA), axial diffusivity (AD), radial diffusivity (RD) and mean diffusivity (MD) were calculated within regions of interest at C2 and C7 levels in the four columns of the spinal cord. Results: At C2, the FA value was decreased in NMO patients compared to MS and controls in the anterior column. Also in this column, RD value showed increase in NMO compared to MS and to controls. The FA value of the posterior column was decreased in NMO in comparison to controls. At C7, AD value was higher in NMO than in MS in the right column. At the same column, MD values were increased in NMO compared to MS and to controls. Conclusions: There is extensive NASC damage in NMO patients, including peripheral areas of the cervical spinal cord, affecting the white matter, mainly caused by demyelination. This suggests a new spinal cord lesion pattern in NMO in comparison to MS Description: p. 2697–2701.: il. color. e p&b. 2012-01-01T00:00:00Z https://ninho.inca.gov.br/jspui/handle/123456789/13602 Title: O Uso da Ressonância Magnética Nuclear na Avaliação do Derrame Pleural Authors: Pessôa, Fernanda Miraldi Clemente; Afonso, Felipe Batista; Melo, Alessandro Severo Alves de Abstract: O objetivo desta revisão é apresentar os principais aspectos do derrame pleural através de técnicas con vencionais e avançadas de ressonância nuclear magnética. Esta modalidade é considerada padrão-ouro para a avaliação da interface pleural e dos derrames pleurais complexos. A indicação deste método na caracterização do derrame pleural é superior em relação à tomografia computadorizada, especialmente em razão da alta resolução na avaliação da pleura. Este estudo revisa as características morfoestruturais e funcionais do derrame pleural livre, loculado, hemorrágico e neoplásico.

Results At C2, FA value was decreased in MS patients. Besides, RD value was higher in MS than in controls. At C7, MD values were increased in MS. Conclusion The NASC in the right column of the cervical spinal cord showed abnormal FA, RD and MD values, which is possibly related to demyelination, since the FA abnormality was related to the RD and not to the AD. diffusion tensor imaging; multiple sclerosis; cervical spinal cord.
