计算SPECT/CT显像的诊断效能。 结果SPECT/CT显像提示螺钉松动23例,椎间融合器无菌性炎性反应6例,撞击综合征9例,15例阴性。SPECT/CT对腰椎融合术后疼痛原因诊断的灵敏度为71.7%(38/53);对内固定器造成并发症诊断的灵敏度及阳性预测值均为100%(38/38)。 结论SPECT/CT显像在解剖影像学检查未能明确腰椎融合术后...
CTPurposeDespite recent advances in lumbar spine stabilization surgery (LSSS), a high number of patients continue to complain of persistent/recurrent lumbar pain after LSSS. Conventional imaging (plain radiography, CT and MRI) is commonly performed to assess potential lumbar pain generators, but ...
Methods Lumbar vertebrae ACC estimates were performed in 50 female patients (mean age 69.88 ± 13.73 years) who had been administered 562.84 ± 102.33 MBq of 99mTc-DPD and had undergone SPECT acquisition 4 h after the injection. The SPECT/CT system was calibrated against a well counter. Images...
[79] reported uptake of Tc-99 m-bisphosponate in the lumbar spine in 50 patients. The quantification of diagnostic tracers is of great interest if one’s aim is to evaluate the course of a disease. Another potential application in this field is the quantification of therapeutic radionuclides...
