BACKGROUND
The aim of this study was to investigate the value of a smartphone-compatible thermal imaging camera in the mapping of the peroneal artery perforators.
METHODS
Twelve consecutive patients scheduled for fibular flap reconstruction were enrolled. The lower limbs were first studied using smartphone-based dynamic infrared thermography (DIRT). During the rewarming, the hotspots were marked, small rubber markers were taped to the registered sites, and then the patients were sent for a CT scan. The diagnostic performance of smartphone-based DIRT was evaluated by comparing the DIRT findings with CT angiography and intraoperative findings.
RESULTS
DIRT detected 42 of the 57 dominant perforators in 24 limbs and resulted in a sensitivity of 73.7% and a positive predictive value of 65.6%.
CONCLUSIONS
The sensitivity and positive predictive value of the smartphone-based DIRT are low. Currently, it should be used as an adjunctive tool together with the established imaging techniques.
背景
本研究旨在探讨智能手机兼容的热成像相机在腓动脉穿支定位中的应用价值。
方法
连续纳入 12 例行腓骨皮瓣重建的患者。首先使用基于智能手机的动态红外热成像（DIRT）对下肢进行研究。在复温过程中，标记热点，在登记部位贴上小橡胶标记，然后将患者送去进行 CT 扫描。通过将 DIRT 结果与 CT 血管造影和术中结果进行比较，评估基于智能手机的 DIRT 的诊断性能。
结果
DIRT 在 24 条肢体中检测到 57 个主要穿支中的 42 个，其灵敏度为 73.7%，阳性预测值为 65.6%。
结论
基于智能手机的 DIRT 的灵敏度和阳性预测值较低。目前，它应作为与现有成像技术相结合的辅助工具使用。
