对接受游离瓣下颌骨重建的病人 ,术后第 2周内 ,连续 2 d作血管和骨的闪烁照相。荧光血管 γ照相的结果与血管的通畅密切相关 ,骨的荧光 γ照相可反映骨的活力。血管 3 -D体层闪烁照相结果难以解释 ,而骨的 3 -D体层闪烁照相可准确反映骨瓣不同部位的活力。提示血管和骨的 3 -D For patients undergoing mandibular reconstruction with a free flap, scintigraphy of the blood vessels and bone was performed for 2 consecutive days in the second week after surgery. Fluorescent blood vessels γ-ray results and vascular patency is closely related to the bone fluorescence γ-ray can reflect the vitality of the bone. Vascular 3-D scintigraphy results are difficult to interpret, and 3-D scintigraphic imaging of bone can accurately reflect the activity of different parts of the bone flap. Prompt vascular and bone 3-D
