Abstract
Objective：To improve the MRI diagnostic accuracy of intracranial cavernous angiomas.
Method：The MRI data，to have been confirmed by surgical operation and pathological test，of 10 cases with intracranial cavernous angiomas were retrospectively reviewed.
Result：100％ local diagnosis and 80％ qualitative diagnosis were found in 10 cases.
Conclusion：It is significant in the diagnosis of intracranial cavernous angiomas using low－field MR.
Key words：MRI；Intracranial cavernous angiomas；Review
颅内海绵状血管瘤是常见的一种血管畸形，临床上以头痛及癫痫为主要症状，本文通过对1996年－2002年我院收集经病理证实的10例海绵状血管瘤的MRl分析，旨在进一步提高对该病的认识。
材料和方法
男6例，女4例，年龄9岁－67岁，平均46.5岁。临床症状主要表现为癫痫发作5例，以头痛为主4例，视力改变1例。10例MRI平扫后做增强扫描，10例中有3例曾做CT平扫。MRI检查：使用德国西门子Magnetom－Open0.2T常导磁共振仪，轴位：TiWI：TR／TE 为400／15ms，T2WI：TR／TE为3500／106ms。质子密度加权TR／TE：3500／26ms，矩阵256x 256。增强造影为钆喷替酸葡甲胺 0.2mmol／kg。 |
