【摘要】 目的：评价应用 EPI技术行弥散加权成像在诊断颅内表皮样囊肿中的作用。方法：对 15例经术后病理证实为颅内表皮样囊肿和 1例术后证实为蛛网膜囊肿的病人行常规 MRI和弥散加权成像。结果：所有表皮样囊肿在弥散加权成像上均表现为高信号，蛛网膜囊肿在弥散加权成像上成低信号。结论： EPI弥散加权成像对诊断表皮样囊肿有价值。更多还原

【Abstract】 Objective:To evaluate the role of diffusion- weighted(DW)echoplanar MRI in diagnosing epidermoid cyst.Methods:We examined 15 patients with epidermoid cysts and one patient with arachnoid cyst,which were proved by the pathological evidence postoperatively,using conventional MRI and diffusion- weighted echoplanar MRI.Results:All epidermoid cysts presented hyperintense signal,and the arachnoid cyst presented signal like CSF on diffusion- weighted imaging.Conclusion:DW echoplanar MRI is valuable in diagnosing intracranial epidermoid cyst.更多还原
