A comparison of single-photon emission computed tomography and planar imaging for quantitative skeletal scintigraphy of the mandibular condyle

Comparison of different analytical methods used for analyzing SPECT scans of patients with unilateral condylar hyperactivity

“…In recent literature, several bone scanning methods, varying from simple planar bone scanning to more sophisticated methods such as SPECT, have been described for evaluating asymmetrical mandibles 2,6,[9][10][11] . In the case of UCH, rather than planar bone scintigraphy, SPECT scanning appears to be a significantly better diagnostic tool 2,9,13 .…”

The use of SPECT to evaluate growth cessation of the mandible in unilateral condylar hyperplasia

“…SPECT is superior to planar scan because it can isolate the two condyles fairly accurately. Earlier studies on SPECT concentrated mainly on comparison with measurements from planar bone scans, and the clivus at the base of skull was used in SPECT instead of the lumbar vertebra as the reference point 2,14 .…”

“…Planar scintigraphy with 99 m Tc-MDP (technetium methylene diphosphonate) has been used to assess growth activity of the condyle 4,6,10,13,17 , but lacked anatomical precision. MDP-SPECT (single photon emission computer tomography) has the capability of 3D reconstruction and subsequent thin sectioning; however, there are at present no discriminating features of MDP-SPECT for assessing condylar growth except for the report of HODDER et al which relied on surgical outcome as the gold standard 3,8,14 .…”

Avaliação da relevância das imagens simultâneas de fusão: SPECT com 99m Tc-MDP e Tomografia Computadorizada aplicada no diagnóstico das Disfunções Temporomandibulares.

“…Nestes casos, o objetivo é somente avaliar se o metabolismo encontra-se em estágio de equilíbrio ou ainda em atividade alterada, com exceção dos casos de suspeita de metástases ósseas (CISNEROS; KABAN, 1984;POGREL et al, 1985;TREVES;MCNEILL, 1973 (COLLIER et al, 1983;HELLMAN;FOGELMAN;MAISEY;CLARKE, 1994;HODDER et al, 2000;KATZBERG et al, 1984;KIRCOS et al, 1988;KRASNOW et al, 1987;POGREL et al, 1995). Embora os estudos de Krasnow et al (1987) Os estudos de Collier et al (1983), Hodder et al (2000, Katzberg et al (1984), Kircos et al (1988), Krasnow et al (1987), Pogrel et al (1995), apontaram maior sensibilidade, especifidade e acurácia do SPECT, na contribuição diagnóstica de DTM, em relação à cintilografia óssea planar e outros exames, tais como radiografia panorâmica, transcraniana, cefalométrica e póstero-anterior, além da tomografia cefalométrica lateral corrigida. Segundo Collier et al (1983) dor esporádica em ATM e ardência lingual, porém era uma paciente com língua geográfica, poliqueixosa que já fora submetida a 5 cirurgias oncológicas, uma delas tireoidectomia total e tinha dificuldade para deglutir.…”

“…Com alto índice de acurácia, 96,7% do SPECT/CT, demonstramos que é um exame superior ao SPECT e demais exames estudados por Collier et al (1983), Hodder et al (2000), Katzberg et al (1984), Kircos et al (1988), Krasnow et al (1987), Pogrel et al (1995.…”
