目的探讨桥脑中央髓鞘溶解症(central pontine myelinolysis,CPM)的MRI表现。方法对桥脑中央髓鞘溶解症MRI诊断3例进行回顾性分析。结果 MRI显示3例均有阳性表现,呈对称性,形态不规则,其中桥脑病灶3例,病灶显示为长T1和长T2信号。病灶在T2WI上最敏感。结论 MRI对桥脑中央髓鞘溶解症病灶显示敏感,FLAIR序列对病灶显示尤为清晰,结合病史可明确诊断。

Objective To discuss the MRI findings of diabetic muscle infarction (DMI).Materials and Methods The MR findings of 3 patients with diabetic muscle infarction were reviewed retrospectively. Of the 3 patients, duration of diabetic mellitus 7.3 years. All patients were men, the mean age was 63.7years, all patients had unilateral involvement.Results Diffuse enlargement of involved muscle with hypointensity on T_1WI, hyperintensity on T_2WI was depicted by MRI, partial loss of normal fatty, subfascial fluid and subcutaneous of edema were also shown on MR. MR T_2 weighted imaging was sensitive in depicting lesions.Conclusion Diabetic muscle infarction is suggested in patients of diabetic with sudden onset of severe pain in the thigh or calf muscles, MR findings are diffuse edema and swelling of multiple thigh and calf muscles.

皮层下动脉硬化性脑病( BD),又称 Binswanger氏病,是脑深部穿透支小动脉硬化和变性所致的弥漫性脑白质病变,可有脑室周围白质和基底节区单个或多个腔隙性梗死,临床上以高血压、卒中、慢性进行性痴呆为三大临床表现的一种综合征.自 CT、 MRI问世以来,该病的临床报道逐年增多,并对本病有了进一步的认识.现收集整理 2003年 5月～ 2004年 5月共收治的 65例 BD患者的 CT、 MRI资料及临床表现报道如下.

2002-05～2004-11我们应用MRI诊断空蝶鞍综合征32例,就其MRI征象总结分析如下.

目前数字化影像设备如 CT、MRI、DSA、SPECT、数字胃肠及数字乳腺等影像设备,已形成数字化影像的发展趋势,使影像科室的数字化建设得到了飞速发展,我院于 2004年 10月新引进并安装 KODAK DiretView CR500系统(计算机 X线摄影 Computed Ridiography- CR),实现了我院影像科内影像的传输、存储、及调阅;并为影像科及全院的图像存储与传输系统(PACS)建设奠定了基础.

Objective:To study the CT findings of spinal osteblastoma.Methods:3 patients with spinal osteoblastoma documented by operation and pathology were performed with CT scanning.Out of these patients,one lesion cancerated into invasive osteoblastoma.Results:The vertebral lamina and pedicle of vertebral arch were the predilection site of spinal osteoblastoma.The CT findings showed cystic-expansible bony destruction,small dot-pathch and macullar calcification with edge light sclerosis,soft tissue mass was found in all patients.Conclusion:CT scanning is better to demonstrate the inner structure of tumor and favourable to the diagnosis and differential diagnosis of this disease.
