The MR imaging and CT findings of corpus callosal injury were analyzed in 32 of 224 patients with acute head injuries. MR imaging was more sensitive than CT in the detection of callosal injuries. All 9 hemorrhagic lesions were visualized on both MR imaging and CT. Fifteen of 23 nonhemorrhagic lesions were not visualized on CT, although all nonhemorrhagic lesions were visualized on MR imaging. Twenty-four lesions of the corpus callosum were located in the splenium, but no lesion was located in the rostrum. Diffuse axonal shear injuries were visualized in 25 patients with callosal injury as associated traumatic lesions. Twenty-three patients with callosal injury had low initial Glasgow Coma Scale scores (less than 9), but 9 patients had high scores. Associated diffuse axonal shear injuries, especially in the brain stem could be a possible explanation for this difference. MR imaging is useful to detect traumatic lesions of the corpus callosum.
在224例急性颅脑损伤患者中，对其中32例胼胝体损伤患者的磁共振成像（MR）和计算机断层扫描（CT）结果进行了分析。在胼胝体损伤的检测中，MR成像比CT更敏感。所有9处出血性病变在MR成像和CT上均能显示。23处非出血性病变中有15处在CT上未显示，尽管所有非出血性病变在MR成像上均能显示。24处胼胝体病变位于压部，但在嘴部未发现病变。在25例伴有胼胝体损伤的患者中，可见弥漫性轴索剪切伤作为相关创伤性病变。23例胼胝体损伤患者初始格拉斯哥昏迷量表评分较低（低于9分），但9例患者评分较高。相关的弥漫性轴索剪切伤，尤其是脑干处的损伤，可能是造成这种差异的一个原因。MR成像有助于检测胼胝体的创伤性病变。
