Effects of iodinated contrast agent, xylocaine and gadolinium concentration on the signal emitted in magnetic resonance arthrography: a samples study

Abstract: ObjectiveTo investigate the effects of dilution of paramagnetic contrast agent with iodinated contrast and xylocaine on the signal intensity during magnetic resonance arthrography, and to improve the paramagnetic contrast agent concentration utilized in this imaging modality.Materials and MethodsSamples specially prepared for the study with three different concentrations of paramagnetic contrast agent diluted in saline, iodinated contrast agent and xylocaine were imaged with fast spin echo T1-weighted sequence… Show more

“…Recent studies conducted in Brazil have emphasized the role of MRI in evaluating the musculoskeletal system, especially the shoulder ( 16 - 19 ) . The labrum is a fibrocartilaginous structure that occupies the transition zone between the underlying articular cartilage and the fibrous tissue of the joint capsule.…”

“…Porém, o seu gasto é duas a quatro vezes maior do que o contraste iônico, o que volve seu uso indiscriminado bastante oneroso. Por isso, uma alternativa relativamente segura é o uso do MC iodado não iônico exclusivamente para ocorrências que simulem maior risco para o acréscimo de reações adversas, ou seja, para pacientes que apresentem qualidades clínicas ou fatores de risco que acrescentem a expectativa destes acontecimentos (SILVA et al, 2015).…”

“…Na área de diagnósticos por imagem, é preciso de uma equipe multidisciplinar, atingindo agilidades como orientação e preparo do paciente para o procedimento; conferência e custeio do material necessário para a efetivação e ocorrência do exame; armazenamento, preparo e administração de contrastes; bem como saimento do paciente antes, durante e após a efetivação do exame, entre outras (SILVA et al 2015).…”

“…However, as in any subjective experience, there is a relevant emotional component, which makes it extremely difficult to measure pain by quantitative methods ( 6 - 8 ) . In addition, there are inherent technical variations, ranging from the type of needle used-usually the type used in lumbar puncture ( 1 , 9 , 10 ) -to the dilution of the contrast agent ( 11 ) and the approach to accessing the glenohumeral joint ( 9 , 12 , 13 ) .…”
