中文摘要:

目的探讨足踝部慢性疼痛患者的SPECT/CT融合图像特征。方法回顾性分析161例足踝部慢性疼痛患者足踝⁹⁹Tc^m-MDP SPECT/CT断层骨显像融合图像特征，包括骨显像剂⁹⁹Tc^m-MDP摄取类型、病灶部位以及CT表现。结果 161例中，⁹⁹Tc^m-MDP摄取增高者158例（158/161，98.14%），3例（3/161，1.86%）无⁹⁹Tc^m-MDP摄取增高；155例（155/161，96.27%）CT出现阳性改变，6例（6/161，3.73%）CT表现阴性，其中4例存在⁹⁹Tc^m-MDP摄取增高病灶。3例⁹⁹Tc^m-MDP摄取阴性患者中，1例CT表现阳性。⁹⁹Tc^m-MDP摄取增高病灶多位于距上关节（81/161，50.31%）和距下关节（56/161，34.78%）；CT阳性病灶表现多为关节面骨质硬化（107/161，66.46%）和骨质密度增高（76/161，47.20%）。结论 SPECT/CT同机融合图像可有效评估足踝部慢性疼痛患者病变特点，对指导临床精准治疗具有一定价值。

英文摘要:

Objective To investigate the characteristics of hybrid SPECT/CT images in patients with chronic foot and ankle pain. Methods Totally 161 patients with chronic foot and ankle pain were enrolled, and the imaging features of ⁹⁹Tc^m-MDP hybrid SPECT/CT scans were analyzed, including ⁹⁹Tc^m-MDP uptake type, lesion location and CT findings. Results Among 161 patients, 158 patients (158/161, 98.14%) were found with elevated ⁹⁹Tc^m-MDP uptake, while 3 (3/161, 1.86%) had no ⁹⁹Tc^m-MDP uptake. Totally 155 patients (155/161, 96.27%) had positive CT findings, whereas 6 (6/161, 3.73%) had no obvious abnormal CT changes. Among 6 patients without CT abnormalities, 4 had elevated ⁹⁹Tc^m-MDP uptake, while among 3 patients without ⁹⁹Tc^m-MDP uptake, 1 had positive CT findings. The elevated ⁹⁹Tc^m-MDP uptake lesions mostly located in the superior joint (81/161, 50.31%) and subtalar joints (56/161, 34.78%). CT positive lesions mostly presented as articular sclerosis (107/161, 66.46%) and increased bone density (76/161, 47.20%). Conclusion Hybrid SPECT/CT images can be used to effectively evaluate the lesion characteristics of patients with chronic pain in the ankle and foot, therefore having potential value of guiding clinical precision treatment.
