脊椎转移瘤MRI特点分析

目的：对低场强磁共振成像患者脊椎转移瘤的特点进行分析。方法：对本院2010年2月-2011年2月40例患有脊椎转移瘤的患者进行回顾性分析，观察其MRI的改变。结果：在40例脊椎转移瘤患者中，单发者15例，多发者25例，其中T1WI主要是低信号，T2WI主要是高低混合的杂信号，压脂序列其所有的病例则都表现为一种高信号。结论：低场磁强共振成像是一种诊断脊椎转移瘤的有效方法，T2压脂序列能够很好地评估其生长方式、已经转移部位等累计范围。

Characteristics Analysis of Spinal Metastatic Tumor MRI

Objective： To analyze characteristics about spinal metastatic tumor of low field magnetic resonance imaging patients. Method： To recall and analyze patients with spinal metastatic tumor in the hospital from February 2010 to February 2011, and observe the change of MRI. Result： Among 40 spinal metastatic tumor patients, there were 15 single patients and 25 multiple patients. The main T1WI was the low signal, and the main T2WI was high and low mixed noise signal. All the patients＇ pressure fat sequence performed a high signal. Conclusion： Low field magnetic resonance imaging is a effective method to the diagnosis of spinal metastasis, and pressure fat sequence T2 can evaluation cumulative range about growth way and transfer parts.
