| 中文摘要: |
| 目的 探讨SE、STIR 和FLASH 三种扫描序列在乳腺疾病MRI 诊断中的作用。方法 应用SE、STIR
和FLASH 三种方法对27 例患乳腺肿块的患者进行MRI 检查,普通平扫后,静注Gd2DTPA 增强扫描。从病灶显示
信噪比、病灶的鉴别诊断方面对三种扫描方法 进行评价。结果 三种扫描序列对乳腺组织及病灶均有良好的信噪
比显示;SE、STIR 扫描速度较慢,不能满足快速扫描的需要; FLASH 扫描速度快,强化扫描时既能满足快速扫描的
需要,又能较好地区分脂肪和腺体。结论 FLASH 是较佳的扫描序列。 |

| Objective To explore the MRI diagnosis of the breast lesions in SE、STIR and FLASH sequences. Methods
27 cases with breast neoplasm underwent the MRI with Gd2DTPA enhancement in SE、STIR and FLASH sequences.
The SNR and the diagnosis of breast lesions were observed and evaluated. Results MRI show that there were the satisfied
SNR for the breast lesions respectively in SE、STIR and FLASH sequences. In three sequences , FLASH sequence was advantageous to the diagnosis of the breast lesions as its speed of tomography was fast . Conclusion FLASH was a recommended sequence. |
