磁共振成像(MRI)具有较高的软组织分辨率,特别是其多方位扫描功能使眶内肿瘤显示极清,恰当的扫描方位、扫描序列等技术条件的选择可更好地显示病变。本文通过对30例眶内肿瘤检查效果的分析,以探讨MRI对眶内肿瘤适当的检查方法。 1.临床资料:经手术证实的眶内眼球后肿瘤30例,其中术前行MRI捡查者21例,手术复发后第一次行MRI检查者9例。术前检查病例中起源于视神经7例(视神经胶质瘤3例,视神经脑膜瘤4例);起
Magnetic resonance imaging (MRI) has a higher resolution of soft tissue, especially its multi-directional scanning function makes the orbital tumor extremely clear, the appropriate scan orientation, scan sequence and other technical conditions to better select the display of lesions. This article through the analysis of 30 cases of orbital tumor examination to explore the appropriate method of MRI orbital tumors. 1. Clinical data: 30 cases of intraorbital retrobulbar tumors confirmed by surgery, of which 21 cases were examined by MRI before surgery, and 9 cases were performed the first MRI after recurrence. Preoperative examination cases originated in the optic nerve in 7 cases (3 cases of optic neuroglioma, optic nerve meningioma in 4 cases);
