artigo de reVisão reView article INTRODUÇÃOO infravermelho é uma radiação do espectro eletromagnético com comprimentos de onda entre 0,75 μm a 100 μm, em meio ao limite da percepção visual do vermelho e as microondas. Dependendo de sua intensidade, elas podem ser percebidas como calor pelas terminações nervosas livres, corpúsculos de Krause e de Ruffini da pele.A imagem infravermelha (IR) é uma técnica que capta radiação na faixa do infravermelho longo (7,5-13 μm) emitido pelo corpo humano, proporcionando uma imagem da distribuição térmica da superfície cutânea. A temperatura da pele, sob condições ambientais cuidadosamente controladas, é influenciada principalmente pela atividade microcirculatória desta e pela produção de calor conduzida para a superfície gerada em tecidos mais profundos.Conhecida desde a década de 1970, na reumatologia, pelo nome de termografia (1)(2)(3)(4)(5) , tem recebido nova atenção nos últimos cinco anos, sendo recentemente renomeada de imagem infravermelha (IR) devido aos novos detectores RESUMOA imagem infravermelha (IR) é um método diagnóstico inócuo e sem radiação iônica, capaz de quantificar objetivamente por imagem as reações inflamatórias locais do sistema músculo-esquelético. Para o diagnóstico diferencial, a imagem IR deve ser analisada em conjunto com o exame clínico e outros exames complementares. A imagem IR quantitativa é útil particularmente quando aplicada na monitoração do curso da atividade inflamatória e da terapia antiinflamatória local e sistêmica. Palavras-chave: reumatologia, imagem infravermelha, raios infravermelhos. ABSTRACTInfrared thermography is unique objective imaging procedure for the quantitative assessment of local inflammatory reactions in parts of the locomotor system. For differential diagnosis the thermographic results should be evaluated in conjuction with clinical examination and other technical procedures. As a means of monitoring the course of the local inflammatory activity, however, quantitative infrared thermography is a useful tool in itself, particularly during the application of local and systemic anti-inflammatory therapy.Keywords: rheumatology, infrared imaging, infrared rays.infravermelhos ultra-sensíveis. É um método inócuo, não-invasivo, não-ionizante, sem contraste, capaz de mensurar a temperatura cutânea a distância com altíssima precisão em forma de imagens de alta resolução. Essa técnica, além de digitalizar as imagens, quantifica a informação em tempo real, distinguindo diferenças de temperatura menores do que 0,07ºC em menos de 0,03 segundo (6)(7)(8)(9)(10)(11)(12)(13)(14)(15)(16)(17)(18)(19)(20)(21) . Recentemente, distintos métodos de imageamento infravermelho foram descritos além do estático: dinâmico com ou sem subtração de imagem, multiespectral e hiperespectral, mapeamento de textura térmica, multimodal, fusão de sensores, fusão com imagens de ressonância magnética (MRIF) e imageamento infravermelho tridimensional com e sem MRIF (21) .A melhor compreensão dessa tecnologia está permitindo avaliar por outra perspectiva a efet...

“…6 7 The poor correlation of this parameter with the other measures is probably secondary to the changes in ambient temperature, the timing in measurements in individual patients, and the need to measure intra-articular S66 RHEUMATOID AKTHRmS temperatures, in order to obtain meaningful results. 2 It is conceivable that the heat distribution index 2 might be a more appropriate measurement. The necessary equipment required to determine this parameter, accurately, however was not available.…”

Twenty patients with longstanding polyarticular rheu~ matoid arthritis (including knee involvement) were se~ lected for this study. The severity of the knee synovitis was assessed before and during treatment (with intraarticular corticosteroid injections) using clinical scores, sonography, and thermography. In all patients, the in· flammation regressed during treatment. During followup, the quantity of synovial fluid, as measured sonographically 10 days after the start of therapy, correlated Q uantification of pain and inflammation in rheumatoid arthritis is a difficult clinical problem; 1 as a result, any evaluation based on patient symptoms is fraught with error. A standardized and reproducible method of grading both the severity of disease and the response to treatment is sorely needed.1.2In the last 20 years, various methods have been proposed to assess the severity of articular involvement, including radioisotope scanningM and thermography.5-7 More recently, the use of sonography and magnetic resonance has been suggested. a-u The aim of the present study is to compare the utility of the sonographic parameters, synovial thickness and 7:561, 1988) intra-articular fluid, with the clinical and thermographic rating systems, 2.5;7 both before and during treatment of rheumatoid arthritis of the knee. MATERIALS AND METHODSSixteen women and four men aged 40 to 73 (mean 59 years) were included in this study. All patients had classical rheumatoid arthritis and were classified according to the grading system of the American Rheumatism As· sociation. u All patients had persistent and disabling knee symptoms despite control of the articular symptoms elsewhere by conventional drug therapy.The mean duration of the rheumatoid arthritis in our group was 10 years (range 2 to 26 years). The duration of the acute exacerbation of knee arthritis ranged between 8 and 52 weeks (mean 21 weeks).According to the rating system of the American Rheumatism Association, eight patients were in stage 1 and 12 were in stage 2. uThe patients were assessed on day 0 (before treatment) and at 10 days and three months after treatment

Thermography of frozen shoulder and rotator cuff tendinitis

et al. 1992

The role of thermography in the diagnosis of soft tissue lesions of the shoulder was evaluated by screening 28 patients with unilateral frozen shoulder and 86 patients with unilateral rotator cuff lesions. Index shoulders were then compared with the normal side. Differences in skin temperature distribution were found in 82% of subjects with frozen shoulder, nearly three-quarters of whom had reduced skin temperature. There was no consistent pattern of shoulder skin temperature found in rotator cuff tendinitis patients (49% normal, 28% reduced, 23% increased). Thermography can be helpful in the diagnosis of frozen shoulder but further studies are required to determine whether it is useful in other soft tissue shoulder lesions.
