The aim of this work was to preliminarily evaluate the sensitivity, specificity, positive predictive value, negative predictive value, and overall accuracy of (68)Ga-citrate PET/CT in a population of patients with suspected bone infections.
We enrolled 31 patients with suspected osteomyelitis or diskitis who underwent a total of forty (68)Ga-citrate PET/CT scans. The results were compared with different combinations of diagnostic procedures (MRI, radiography, CT, or white blood cell scintigraphy), biopsy (when diagnostic), and follow-up data (at least 1 y) to determine the performance of (68)Ga-citrate PET/CT.
We found a sensitivity of 100%, a specificity of 76%, a positive predictive value of 85%, a negative predictive value of 100%, and an overall accuracy of 90%.
Although preliminary, these data confirm a possible role for (68)Ga-citrate in the diagnosis of bone infections, especially in consideration of its favorable characteristics.
目的 本研究旨在初步评估(68)Ga-枸橼酸盐 PET/CT 在疑似骨感染患者中的灵敏度、特异性、阳性预测值、阴性预测值和总准确率。
方法 我们纳入了 31 例疑似骨髓炎或椎间盘炎患者,共进行了 40 次(68)Ga-枸橼酸盐 PET/CT 扫描。将结果与不同的诊断程序(MRI、X 线摄影、CT 或白细胞闪烁扫描)、活检(当诊断为阳性时)以及随访数据(至少 1 年)进行比较,以确定(68)Ga-枸橼酸盐 PET/CT 的性能。
结果 我们发现(68)Ga-枸橼酸盐 PET/CT 的灵敏度为 100%、特异性为 76%、阳性预测值为 85%、阴性预测值为 100%和总准确率为 90%。
结论 尽管这是初步数据,但这些数据证实了(68)Ga-枸橼酸盐在诊断骨感染方面可能具有一定作用,尤其是考虑到其良好的特征。
