We report a case of heat stroke in which detection of brain injury was improved by high b-value diffusion-weighted imaging (DWI). High b-value DWI revealed moderate to marked hyperintensity at/around bilateral dentate nuclei and part of thalami. Apparent diffusion coefficient maps revealed apparent diffusion coefficient decrease of the dentate lesions. Routine DWI showed only mild hyperintensity of part of dentate lesions. High b-value DWI could be valuable for improved detection of heat stroke-induced brain injury.
我们报告了一例热射病病例，其中通过高b值扩散加权成像（DWI）改善了脑损伤的检测。高b值DWI显示双侧齿状核及部分丘脑处/周围呈中度至明显高信号。表观扩散系数图显示齿状核病变的表观扩散系数降低。常规DWI仅显示部分齿状核病变呈轻度高信号。高b值DWI对于改善热射病所致脑损伤的检测可能具有重要价值。
