新型磁共振造影剂介孔二氧化硅钆掺合纳米颗粒的研制

Zhongshan Daxue xuebao. Yixue kexue ban, 2011
【目的】 研制一种新型顺磁性高的含钆纳米材料介孔二氧化硅钆掺合纳米颗粒(Gd-MCM-41)，评估其应用于影像学诊断的可行性。【方法】 将Gd掺合到MCM-41的介孔孔道中，制备含钆纳米材料Gd-MCM-41，透射电镜观察该纳米材料特征；X-射线能谱仪测量复合材料内的钆含量；0.5T核磁共振分析仪测定该材料的弛豫率R1、R2；1.5T磁共振成像系统观察其在Balb/c裸鼠体内和鼻咽癌CNE-2裸鼠移植瘤的分布特点。【结果】 制备的含钆纳米颗粒呈圆球形，直径约80~150 nm。X ...

大及巨大泌乳素腺瘤经蝶术后早期疗效评估———内分泌及磁共振成像检查对照分析

Zhongshan Daxue xuebao. Yixue kexue ban, 2004
【目的】探讨、分析内分泌及磁共振成像(MRI)检查对大及巨大泌乳素腺瘤经蝶术后早期疗效评估的意义。【方法】追踪、随访37例经蝶手术的最大直径≥2cm泌乳素腺瘤患者,动态监测术后内分泌及磁共振成像变化并分析比较。【结果】术后早期MRI可明确诊断瘤影消失者16例,术后3月MRI可明确诊断瘤影消失者25例,术后6月MRI可明确诊断瘤影消失者30例。术后1～2周泌乳素恢复正常者30例,泌乳素持续异常者7例。【结论】术后泌乳素是早期判定大及巨大泌乳素垂体腺瘤经蝶手术疗效的敏感指标 ...
